Detailed explanation-1: -When a small meteor enters the Earth’s atmosphere, it goes from traveling through a vacuum to traveling through air. Traveling through a vacuum is effortless–it takes no energy.
Detailed explanation-2: -Most meteorites reach the Earth’s surface in the form of dust or very small particles after passing through the atmosphere, which is why we do not normally see them. However, believe it or not, some 17, 000 meteorites fall to Earth every year.
Detailed explanation-3: -Meteorites are small rocks from space that impact the Earth. They are exceedingly rare-the collective weight of every meteorite known to exist is less than the world’s annual output of gold. The vast majority originate from the ‘asteroid belt’ and hail from 100-150 different asteroids.
Detailed explanation-4: -Meteoroids become meteors when they crash into Earth’s atmosphere and the gases surrounding them briefly light up as “shooting stars.” While most meteors burn up and disintegrate in the atmosphere, many of these space rocks reach Earth’s surface in the form of meteorites.
Detailed explanation-5: -The Earth’s atmosphere protects us from the multitude of small debris, the size of grains of sand or pebbles, thousands of which pelt our planet every day. The meteors in our night sky are visible evidence of this small debris burning up high in the atmosphere.
