    What could happen to the water table if all the wells start pumping at once?

    answer choices

    the water table may fall

    the water table may rise

    the boat will sink

    the wells will overflow

    2. Multiple-choice 30 seconds Q.

    Groundwater feeds the river systems.  Groundwater and surface water are connected, not separate.  Consequently, water wells may remove or intercept groundwater that was on its way to springs that feed streams and rivers.  What can happen to water level if too many wells are placed together?

    answer choices

    they may cause the water table to rise

    they may draw down the water table

    the rivers will all run dry

    rainwater will stop falling

    3. Multiple-choice 30 seconds Q.

    The carbonic acid created when carbon dioxide dissolves in rainwater is caustic to the limestone rock in the Valley and Ridge region of Virginia.  The acidic water melts away parts of the carbonate rock, limestone, to create fascinating structures within the ground.  What are the structures at A and E, respectively?

    answer choices sand sandy loam clay 5. Multiple-choice 30 seconds Q.

    The rock shown in the picture is an extrusive igneous rock called pumice.  It is made when the gaseous, frothy effluent from a volcano cools rapidly above ground.  In fact, pumice is so lightweight from all the holes that it floats in water.  Please note that the holes are large, but they don't connect to each other.  Pumice is best described as

    space exploration, investigation, by means of crewed and uncrewed spacecraft, of the reaches of the universe beyond Earth’s atmosphere and the use of the information so gained to increase knowledge of the cosmos and benefit humanity. A complete list of all crewed spaceflights, with details on each mission’s accomplishments and crew, is available in the section Chronology of crewed spaceflights.

    Humans have always looked at the heavens and wondered about the nature of the objects seen in the night sky. With the development of rockets and the advances in electronics and other technologies in the 20th century, it became possible to send machines and animals and then people above Earth’s atmosphere into outer space. Well before technology made these achievements possible, however, space exploration had already captured the minds of many people, not only aircraft pilots and scientists but also writers and artists. The strong hold that space travel has always had on the imagination may well explain why professional astronauts and laypeople alike consent at their great peril, in the words of Tom Wolfe in The Right Stuff (1979), to sit “on top of an enormous Roman candle, such as a Redstone, Atlas, Titan or Saturn rocket, and wait for someone to light the fuse.” It perhaps also explains why space exploration has been a common and enduring theme in literature and art. As centuries of speculative fiction in books and more recently in films make clear, “one small step for [a] man, one giant leap for mankind” was taken by the human spirit many times and in many ways before Neil Armstrong stamped humankind’s first footprint on the Moon.

    Achieving spaceflight enabled humans to begin to explore the solar system and the rest of the universe, to understand the many objects and phenomena that are better observed from a space perspective, and to use for human benefit the resources and attributes of the space environment. All of these activities—discovery, scientific understanding, and the application of that understanding to serve human purposes—are elements of space exploration. (For a general discussion of spacecraft, launch considerations, flight trajectories, and navigation, docking, and recovery procedures, see spaceflight.)

    Overview of recent space achievements

    Overview of recent space achievements Motivations for space activity

    Although the possibility of exploring space has long excited people in many walks of life, for most of the latter 20th century and into the early 21st century, only national governments could afford the very high costs of launching people and machines into space. This reality meant that space exploration had to serve very broad interests, and it indeed has done so in a variety of ways. Government space programs have increased knowledge, served as indicators of national prestige and power, enhanced national security and military strength, and provided significant benefits to the general public. In areas where the private sector could profit from activities in space, most notably the use of satellites as telecommunication relays, commercial space activity has flourished without government funding. In the early 21st century, entrepreneurs believed that there were several other areas of commercial potential in space, most notably privately funded space travel.
