    In essence, the holds that _________.

    our solar system formed from the collapse of an interstellar cloud of gas and dust

    According to modern science, what was the approximate chemical composition of the solar nebula?

    98% hydrogen and helium, 2% everything else

    98% hydrogen and helium, 2% everything else

    They were produced by stars that lived and died before our solar system was born.

    According to our theory of solar system formation, what three major changes occurred in the solar nebula as it shrank in size?

    It got hotter, its rate of rotation increased, and it flattened into a disk.

    Which of the following types of material can condense into what we call at low temperatures?

    hydrogen compounds

    According to our present theory of solar system formation, which of the following lists the major ingredients of the solar nebula in order from the most abundant to the least abundant?

    hydrogen and helium gas; hydrogen compounds; rock; metal.

    What do we mean by the when we discuss the formation of planets in the solar nebula?

    It is a circle at a particular distance from the Sun, beyond which the temperature was low enough for ices to condense.

    What do we mean by in the context of planet formation?

    The growth of planetesimals from smaller solid particles that collided and stuck together

    According to our present theory of solar system formation, why were solid planetesimals able to grow larger in the outer solar system than in the inner solar system?

    Because only metal and rock could condense in the inner solar system, while ice also condensed in the outer solar system.

    According to our basic scenario of solar system formation, why do the jovian planets have numerous large moons?

    As the growing jovian planets captured gas from the solar nebula, the gas formed swirling disks around them, and moons formed from condensation accretion within these disks.

    According to our theory of solar system formation, what are asteroids and comets?

    Leftover planetesimals that never accreted into planets

    According to our theory of solar system formation, where did the comets of the form?

    in the region of the jovian planets

    What do we mean by the period of in the context of the history of our solar system?

    The first few hundred million years after the planets formed, which is when most impact craters were formed.

    What is the for the origin of the Moon?

    The Moon formed from material blasted out of the Earth's mantle and crust by the impact of a Mars-size object.

    The Moon formed from material blasted out of the Earth's mantle and crust by the impact of a Mars-size object.

    You'll have 0.25 kilogram of the radioactive substance remaining.

    You'll have 0.25 kilogram of the radioactive substance remaining.

    4.5 billion years Condesation

    The general process in which solid (or liquid) particles in a gas

    Accretion

    The process by which small "seeds" grew into planets

    Pieces of planets Planetesimals Meteorites

    rocks that have fallen to earth from space

    4 features for the solar system formation

    Pattern of Motion (Heating- the temperature increases, Spinning - rotates faster and shrinks, Flattening - the solar nebula flattened into a disk)

    2 types of planets (terrestrial and jovian)

    Asteroids and Comets (Asteroids and Comets are left overs from the era of planet formation. Asteroids are rocky leftovers in the inner solar system and comets are icy leftovers in the outer solar system.)

    Explaining the exception to the rules (Most of the exceptions probably arose from collisions or close encounters with leftover planetesimals. Or Moon is most likely the result of a giant impact between a Mars-size planetesimal and the young Earth.)

    Frostline

    the distance at which it was cold enough for ices to condense which lay between the present day orbits of Mars and Jupiter.

    Terrestrial vs. Jovian Planets

    Terrestrial - inner planets that are made of rocky a metal

    Jovian - outer planets made of ice and some rocky and metal.

    Nebular Theory

    stated for many years that the planets were made by debris from near collision between the Sun and another Star.

    In 1755, German philosopher Immanuel Kant proposed that our solar system formed from the gravitional collapse of an interstellar cloud of gas. 40 years later Pierre-Simon Laplace put forth the same idea independently. Because an interstellar cloud is usually called a NEBULA (cloud) their idea came to be the nebula theory

    A. They were produced by stars that lived and died before our solar system was born.

    B. They were produced by gravity in the solar nebula as it collapsed.

    C. They were made by chemical reactions in interstellar gas.

    D. They have been present in the universe since its birth.

    They were produced by stars that lived and died before our solar system was born.

    -That is why we say that we and our planet are made from "star stuff."

    According to our theory of solar system formation, what three major changes occurred in the solar nebula as it shrank in size?

    A. Its gas clumped up to form the terrestrial planets, nuclear fusion produced heavy elements to make the jovian planets, and central temperatures rose to more than a trillion Kelvin.

    6) According to our theory of solar system formation, why do all the planets orbit the Sun in the same direction and in nearly the same plane? Through active plate tectonics c. Through large convective currents of hot magma that rise beneath its crust d. According to the Solar Nebula theory, planets: a. should be a common result of star formation. In essence, the nebular theory holds that: Our solar system formed from the collapse of an interstellar cloud of gas and dust It is a discarded idea that imagined planets forming as a result of a near-collision between our Sun and another star. -hydrogen, step two (2) -A disturbance. Ðsmall, rocky terrestrial planets Ðlarge, hydrogen-rich Jovian planets 3.Asteroids & comets exist in certain regions of the Solar System 4.There are exceptions to these patterns. A theory is a hypothesis that has withstood many scientific tests. The solar system's birth story is an unfolding tale. Ø Condensation, according to the solar nebula theory, the observed pattern of planet densities originated when solid grains first formed. Describes the nebular hypothesis for the formation of the sun and planets of our solar system and the scientific evidence for the hypothesis. It is the most widely accepted model, also known as the "solar nebular hypothesis." The nebular theory describes the formation of the sun, planets, moons and asteroids around 4.5 billion years ago from a nebula cloud comprising dust and gas, according to . • The nebular theory states that solar system formed from a large interstellar gas cloud. A. the inner planets were the first to condense from the solar nebula . Not only that, but our Sun is but one . After the solar nebula collapsed to form our Sun, a disk of material formed around the new star. According to the Solar Nebula theory, planets A) will revolve opposite the star's rotation. How does Venus release its interior heat? Here is a brief outline of the current theory of the events in the early history of the solar system: A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. . In fact it was these observations which lead to the proposal of the theory in the first place. solar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. According to the nebular hypothesis, the inner planets are dense and rocky because _____. they are all irregular in shape without exception. S olar nebula, gaseous cloud from which, in the so-called nebular hypothesis of the origin of the solar system, the Sun and planets formed by condensation. It's believed that during the early formation of our solar system, a young Earth and an object about the size of Mars collided, sending debris into space and reforming within Earth's gravity and. According to this theory, the Sun and all the planets of our Solar System began as a giant cloud of molecular gas and dust. ; 4 Why did the solar nebula flatten into a disk Why did the solar nebula flatten into a disk? Contents. Pre-solar nebula synonyms, Pre-solar nebula pronunciation, Pre-solar nebula translation, English dictionary definition of Pre-solar nebula. Solar system origin: Nebular hypothesis. Essentially, through accretion, these collisions led to larger and larger masses clumping together. The nebular theory it explains the formation of our solar system and by extension of the other planetary systems. Ø Condensation Sequence is the sequence in which different materials condense from the gas as you move away from the sun toward lower temperature. . THE SOLAR NEBULA THEORY • Supposes that planets form in the rotating disks of gas and dust around young stars. step four (2) -Inner planets began to form from metallic. But as we have learned, the inner planets and outer planets have radically. In the early 20th century, the nebular hypothesis was rejected and the planetesimal hypothesis, that the planets were formed from material drawn out of the sun, became popular.This theory, too, proved unsatisfactory. What are the theory of origin of the earth? D) should be extremely rare. And the motions of most solar system objects orbit and rotate in an organized fashion. This indicates how strong in your memory this concept is. Its details were made known for the first time in 1796 thanks to Pierre de Laplace (1749-1827). Learning Objectives. B) should be a common result of star formation. The temperature across this protoplanetary disk was not uniform. c. should be randomly oriented to their stars equator. A solar system is a group of heavenly bodies consisting of a star and the planets and other objects orbiting around it. All the planets orbit the Sun in the same direction. According to this hypothesis, planets were formed from material drawn from the Sun. What are the 6 stages of nebular theory? According to the nebular hypothesis, gravity caused gas and dust to turn into larger and more compact clouds. 14) According to the nebular theory as the nebula collapses, _____ in the collapsing, rotating cloud cause local regions to begin to _____. Q: According to the nebular hypothesis, how did the solar system form? E) should be extremely rare. Explanation;-Nebular theory describes the forces and processes at play as a nebular spins, accretes, and forms into a star and its planets.-The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over . Practice. Planets would form in the terrestrial region within 107 years but, according to Safronov's theory, it would take 1.5 × 10 8 years to produce a Jupiter core and 10 10 years or more to produce Neptune — more than twice the age of the solar system. The word "nebula" is Latin for "cloud," and according to the explanation, stars are born from clouds of interstellar gas and. As the growing jovian planets captured gas from the solar nebula, the gas formed swirling disks around them, and moons formed from condensation accretion within these disks. It offered explanations for a variety of properties of the Solar System, including the nearly circular and coplanar orbits of the planets, and their motion in the same direction as the Sun's rotation. 8 What are the chemical and physical properties of the solar system that any theory of its origin must explain? They describe the planet-making process from its initial beginnings from an interstellar dust and gas cloud to the achievement of the stable planetary arrangement that we have today. ¥Most inhabit the asteroid belt between Mars & Jupiter. b. should orbit perpendicular to their star's equator. gas becomes hot and dense and forms a star. Current Theory on the Formation of the Solar System - Part I John Clevenger. According to current theory, the formation of the planets of our solar system occurred as a result of collisions between increasingly large bodies of matter within a flattened cloud of matter circling the early Sun, known as a protoplanetary disk. 12 What . In fact it was these observations which lead to the proposal of the theory in the first place. Because of the conservation of angular momentum, the nebula spun faster as it collapsed. By calistagoetz. The solar nebular theory explains the formation and evolution of the solar system. e. should be extremely rare. Our system consists of the sun and the planetary bodies orbiting it such as the eight (formerly nine) planets, three dwarf planets, about 160 known planetary satellites (), and countless asteroids.The solar system also consists of many various icy bodies, and vast amounts of . Our Solar System Formation of a solar system according to the Big Bang Theory Nebula 62)The dust and gas clump together in huge interstellar clouds called nebulas (or nebulae), Solar Nebula A nebula that has collapsed inward from its own gravity Under great pressure the gas ignites and begin to burn A star is born Solar Nebula is a nebula with a star Planets Form Because of their greater . Observations of the solar system itself support the theory too. answer choices constants, expand The solar nebula was the rotating, flattened disk of gas and dust from which the solar system originated ~4.6 Ga ago (Figure 1).Cosmochemical studies of meteorites, comets, and other primitive bodies have illuminated the chemical conditions in the solar nebula, allowing people to gain important insight into the processes that occurred during the formation of the planets. Accretion is the keyword in current planet formation theory. According to this model, the internal zonation of the planets developed during, not after, accretionary accumulation. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then broken apart. All the orbits of the planets are prograde (i.e. What is the solar nebula theory? Nebulae are clouds of gas and dust in space. % Progress . step three (2) -The solar nebula assumed a flat, disk shape. 1. Any model of Solar System formation must explain the following facts: 1. Nebula theory is the hypothesis concerning the origin of the solar system according to which a rotating nebula cooled and contracted, throwing off rings of matter that contracted into planets and . . In 1755 the German philosopher Immanuel Kant suggested that a nebula in slow rotation . • According to this theory, Earth and other planets of the solar system formed billions of years ago as the sun condensed from a cloud of interstellar gas and dust. MEMORY METER. According to the nebular theory, all planets around a star should be tilted the same way relative to the ecliptic. Theory: Summary Origin of the Asteroids ¥The Solar wind cleared the leftover gas, but not the leftover planetesimals. a. heating b. flattening c. accretion d. condensation e. gravitational collapse 2. According to traditional views, our solar system was born when some other nearby star exploded, and the shockwave from that supernova caused the dust and gases within a nebula to compress and… Describe the processes that took place according to the solar nebula theory and specifically how it came to be that we have a star and planets rotating around that star and the orbital motion of the planets is all in the same plane and the same direction. Jovian planets started out with solid material as well, and were far enough from the sun for a layer of ice to form, after which they became massive enough to capture slower-moving gases. 1 CE. by Jonathan Sarfati. By calistagoetz. Ø Ice Line is a boundary beyond which water vapor could freeze to form ice particles. Accretion is thought to have begun with the solar nebula at a time when the gases were still very hot (> 1000 C). . B) Any planets that once orbited in the opposite direction or a different plane were ejected from the solar system. • Galactic recycling built the elements from which planets formed. The solar nebula is a cloud of interstellar gas and dust that condensed to form the entire solar system, including the sun and planets. Some astronomers suggest that a shockwave from a nearby supernova may have triggered the collapse of the nebula. "The only possible source is solar nebula gas." According to Patel, the scientists' leading theory surrounds early interactions between water-logged asteroids, which crashed into each other . 2.There are two types of planets. Solar nebula theory synonyms, Solar nebula theory pronunciation, Solar nebula theory translation, English dictionary definition of Solar nebula theory. Our solar system was created from a dust and gas cloud called the solar nebula. Terms in this set (5) step one (4) -The solar nebula consisted of. D)The solar nebula differentiated into metals inside of the frost line and ices beyond. 1 CE. •Kant and Laplace proposed the nebular hypothesisover two centuries ago. What's more, according to a leading theory now being explored in detail, that early era was capped by a truly cataclysmic event. •A large amount of evidence now supports this idea. Our theory must explain the data 1.Large bodies in the Solar System have orderly motions. ; 2 What is the theory of the formation of our solar system? Answer (1 of 4): In the past, there were a number of different hypotheses for the formation of the Solar System. 6) _____ The theory argued that this nebula condensed into rings, which eventually formed the planets and a central mass - the Sun. 11 What is the most common chemical compound in the solar system? According to the eye-witness account in Genesis, God created the earth on Day 1, and the sun and moon on the Fourth Day, most likely along with the planets. Summarize the physical and chemical changes during the solar nebula stage of solar system formation. The solar nebula flattens into disk. all of the planets formed from a uniform solar nebula: D. . According to a new theory . The Origin of the Solar System. Most of their moons also orbit in that direction, and the planets (and the Sun) rotate in the same direction. The cloud was about 20 parsec (65 light years) across, while the fragments were roughly 1 parsec (three and a quarter light-years) across. T he solar nebula is initially a thin gas of hydrogen and helium strewn with tiny dust particles. Explain the formation process of the terrestrial and giant planets. About 3.9 billion years ago, the movement of the most massive planets dramatically rearranged the outer solar system. What happens first in nebular theory? You might like . ¥Those leftover rocky planetesimals which did not accrete onto a planet are the present-day asteroids. A) The original solar nebula happened to be disk-shaped by chance. 7 What are the composition of the solar system? The Solar Nebula Theory According to the Solar Nebula theory, the Solar System was formed approximately 5 billion years ago from a massive cloud of gas and dust (the solar nebula) that began to contract. Formation of the Sun and Planets. Really, it's not "the Earth's origin story" alone so much as it is the origin story of the whole solar system. THE SOLAR NEBULA THEORY • Supposes that planets form in the rotating disks of gas and dust around young stars. (Of course, this would not be available for the first generation of stars.) The idea is that the planets formed out of the solar nebula, the material left over after the Sun formed. ÐJupiterÕs gravity prevented a planet from forming there. The shifting planets freed rocky and icy bodies from the solar system's edge, commencing a . The standard model for the formation of the Solar System (including the Earth) is the solar nebula hypothesis. According to our theory of solar system formation, what three major changes occurred in the solar nebula as it shrank in size? E)Large planetesimals captured atmospheres from the solar nebula. Nebula theory is the hypothesis concerning the origin of the solar system according to which a rotating nebula cooled and contracted, throwing off rings of matter that contracted into planets and . The disturbance could be, for example, the shock wave from a nearby supernova. According to this theory, the nebula begins to collapse because of its own gravity. Terrestrial planets formed from solid material that condensed out of the solar nebula close to the sun, where it was too hot for them to capture gases. According to the nebular hypothesis, the outer two planets may be in the "wrong place". What three major changes occurred in the solar nebula as it shrank in size? they are predominantly icy in composition. Swedish philosopher Emanuel Swedenborg in 1734 proposed that the planets formed out of a nebular crust that had surrounded the Sun and then broken apart. Solar Nebula is a large disc-shaped cloud of gas and dust from which planets, the sun, and other bodies of a solar system are formed. 1 According To Our Theory Of Solar System Formation, Why Does The Sun Rotate Slowly Today?? E) should be randomly oriented to their star's equator. After this, the Solar Wind swept away any remaining dust and gas, ending the planetary formation process in the SOLAR NEBULA. B) should orbit perpendicular to their star's equator. © 2017 Pearson Education, Inc. 8.2 Explaining the Major Features of the Solar System • Our goals for learning: •What caused the orderly patterns of motion in our solar system? According to the nebular theory of solar system formation, the terrestrial planets were formed from silicates and metals. These tiny grains serve as the building blocks of the planets. After this, the Solar Wind swept away any remaining dust and gas, ending the planetary formation process in the SOLAR NEBULA. Solar nebula theory synonyms, Solar nebula theory pronunciation, Solar nebula theory translation, English dictionary definition of Solar nebula theory. Condensation Theory: An extension of Nebular Theory that incorporates interstellar dust as a key ingredient. Some elements of the original nebular theory are echoed in modern theories of planetary formation, but most elements have been superseded. The Jovian planets are the large planets namely Saturn, Jupiter, Uranus, and Neptune. What are the steps of the nebular theory? According to solar nebula theory, what is the first step in planetesimal formation? Uranus and Neptune (known as the "ice giants") exist in a region where the reduced density of the solar nebula and longer orbital times render their formation there highly implausible. The terrestrial planets include the Earth, Mercury, Mars, and Venus. 6)According to our theory of solar system formation, why do all the planets orbit the Sun in the same direction and in nearly the same plane? (A) As the nebula began to cool, primitive Fe and Ni accumulated first to form the metallic core of the planet. A solar nebula forms. Solar Nebula Theory. The nebular theory is an explanation for the formation of solar systems. However, evolutionists reject a Creator a priori, so need to come up with another explanation. According to the Solar Nebula theory, planets According to the Solar Nebula theory, planets A) should be randomly oriented to their star's equator. Through solar wind b. The word "nebula" is a Latin word for "cloud." The solar nebula was a twisting, flattened disk of gas and dust from which the solar system originated ~ 4.6 Ga ago, where Nebulae are made of residue and . The prevailing scientific explanation for the origin of the Earth does a good job of not only explaining the Earth's formation, but the Sun and all the other planets too.
