Explain why the number of meteors striking the moon’s surface is quite large whereas very few reach the earth’s surface?

The number of meteors striking the moon’s surface is quite large because moon has no atmosphere (air) to burn the falling meteors by frictional heat. On the other hand, the earth has an atmosphere containing air, so many of the meteors burn up completely on entering the earth's atmosphere due to heat produced by friction between falling meteors and air.
