    How does sunspot activity affect Earth?

    If sunspots are active, more solar flares will result creating an increase in geomagnetic storm activity for Earth. Therefore during sunspot maximums, the Earth will see an increase in the Northern and Southern Lights and a possible disruption in radio transmissions and power grids.

    Which of these layers of the Sun is the hottest?

    Core. The hottest part of the Sun is the core, at 28,080,000°F, on average.

    Why do stars have color?

    The color of a star is linked to its surface temperature. The hotter the star, the shorter the wavelength of light it will emit. The hottest ones are blue or blue-white, which are shorter wavelengths of light. Cooler ones are red or red-brown, which are longer wavelengths.

    Why do sunspots appear dark in pictures of the sun?

    Sunspots appear dark (in visible light) because they are much cooler than the rest of the surface of the Sun. However, even though they appear dark, they are still very hot. … If a sunspot was alone in space, it would glow brightly.

    What would happen in the sun if fusion reactions suddenly ceased quizlet?

    We would be able to tell that fusion reactions had ceased because we would no longer detect neutrinos from the Sun. Neutrinos, a by-product of nuclear fusion, exit the Sun immediately. ... The rate at which fusion generates energy in the Sun's core and the rate at which the Sun's surface radiates energy into space.

    What would happen in the Sun a fusion reaction suddenly ceased?

    If nuclear fusion reactions at the core of the Sun mysteriously 'suddenly stopped entirely', the overlying (mostly hydrogen) layers would fall toward the core due to decreased radiation pressure. The diameter would decrease.

    Which of these layers of the sun is coolest which of these layers of the sun is coolest?

    The photosphere The photosphere, which is outside the core, is the coolest layer. This is as expected, because normally heat passes outwardly from hot to cold. However, the Sun's outermost atmospheric layer is much hotter than its surface layer!

    Why does the Sun not collapse under its own gravity?

    It is only because the inner parts of the Sun are hotter that the Sun doesn't collapse under its own gravity. ... The force which they exert is described by the pressure; the internal pressure is higher than the external pressure, so the Sun is held up against gravitational collapse.

    Does the Sun have Corona?

    The corona is the outer atmosphere of the Sun. It extends many thousands of kilometers (miles) above the visible "surface" of the Sun, gradually transforming into the solar wind that flows outward through our solar system.

    Why is corona hot?

    The corona reaches a million degrees C or higher (over 1.8 million degrees F). ... He theorized that magnetized waves of plasma could carry huge amounts of energy along the sun's magnetic field from its interior to the corona. The energy bypasses the photosphere before exploding with heat in the sun's upper atmosphere.

    How hot is a blue star?

    The hottest stars are blue, with their surface temperatures falling anywhere between 10,000 K and 50,000 K.

    Which of the star has the highest temperature?

    The Wolf-Rayet star WR 102 is the hottest star known, at 210,000 K.

    What happens in the corona layer of the Sun?

    Yet the corona is hundreds of times hotter than the Sun's surface. A NASA mission called IRIS may have provided one possible answer. The mission discovered packets of very hot material called "heat bombs" that travel from the Sun into the corona. In the corona, the heat bombs explode and release their energy as heat.

    How does the Sun's magnetic field affect the corona?

    Coronal loops and streamers The surface of the Sun is covered in magnetic fields. This is the force that makes magnets stick to metal, like the door of your refrigerator. The Sun's magnetic fields affect charged particles in the corona to form beautiful features. These include streamers, loops, and plumes.

    What color of star is our sun?

    Which of these stars has the greatest surface temperature which of these stars has the greatest surface temperature?

    Type O stars have the highest surface temperatures and can be as hot as 30,000 Kelvins.

    Which star has the lowest surface temperature?

    red The lowest temperature stars are red while the hottest stars are blue. Astronomers are able to measure the temperatures of the surfaces of stars by comparing their spectra to the spectrum of a black body.
