You might have observed the sudden flash of a bright moving object in the night sky. These bright trails are left by pieces of rocks in outer space, known as meteors. Millions of meteors speed towards our Earth every day, but they burn up due to the friction caused by Earth’s atmosphere.
The Moon does not have an atmosphere to blanket itself. Therefore, there is no friction that would burn the pieces of rock approaching the Moon at great speeds. As a result, they crash on the surface of the Moon, forming lunar soil.
