When we see a bright light moving quickly across the night sky, we often talk about seeing a "shooting star" or a "falling star".These moving lights are not in【C1】_________stars at all.They are small pieces of matter from outer space that burn up as they enter the Earth’s atmosphere.The correct name for these 【C2】ob_________is meteoroids.Any pieces that make it to the Earth’s surface without 【C3】_________(complete) burning up are known as meteorites.Meteor is actually the name given to the light we see when a meteoroid is burning up.
If a large enough meteorite hit the Earth, it could knock the planet out of its orbit, which would have catastrophic results.The path we follow around the sun would change and the Earth would become【C4】_________much hotter or much colder as a result.This change in【C5】tern_________would affect sea levels and the amount of water in rivers.There would either be huge floods or the oceans would dry up causing a【C6】_________(dry).All life on the Earth would probably become extinct.Although it is unlikely that the Earth will be struck by a meteorite large enough to do this kind of damage, there is【C7】evi_________of quite a large meteorite hitting the Earth in the past.In 1908, a large area of forest in Tunguska, Siberia, was destroyed by a meteorite that came apart just before it hit the ground.The moon, however, has about three billion craters, caused by meteorites crashing【C8】 _________its surface.It has so many craters because it does not have enough atmosphere in which the meteoroids can burn up.
Some of the meteorites that have reached the Earth’s surface have done considerable damage.Some scientists believe that it was a change of climate, caused by meteorites hitting the Earth, that resulted in the【C9】_________(extinct) of the dinosaurs and other large prehistoric animals.Scientists are especially interested in meteorites because they contain information about the solar system.It is【C10】 wi _________believed that most meteorites were produced billions of years ago by collisions between asteroids (small planets).This means that the physical and chemical structure of a meteorite can give scientists information about the early universe.
