They are hitting air molecules at a high speed and breaking them apart, which produces a lot of heat.
The air itself protects us from smaller meteors. They burn up before reaching the surface. It cannot protect us from very large ones.
Meteors occur in earth's atmosphere, day and night. Only the large ones are visible in the day. The streak is largely the result of an after image, temporarily burned upon your retina. The light comes from the heat ablation of the meteor's surface from atmospheric friction. Most meteors are roughly the size of a grain of sand, and burn up before reaching the ground.

A meteor IS a what you call a body of matter when it enters earth's atmosphere. A meteoroid is what you call a body of matter in space that hasn't entered earth's atmosphere. Source: Dictionary.com http://dictionary.reference.com/browse/meteor
Because... there's almost no atmosphere on the moon. On Earth - the atmosphere causes meteorites to heat up to the point that they usually evaporate before striking the surface. On the moon - they don't heat up enough, and survive to land on the surface.
Not all meteors disappear before reaching the earth. The friction they feel as a result of rubbing with the molecules of the earth's atmosphere cause them to burn up. However, a few larger ones will make it to the earths surface.
Meteors do not orbit the Sun. Meteors are to be found/seen in the Earth's atmosphere burning up. Before they enter the Earths atmosphere they are called meteoroids and if they land on Earth they are called meteorites.

Meteors!

they have to make it through the atmosphere before the atmoshere burns it up.
The correct name for a shooting star is a Meteorite. Before a meteorite enters the Earths atmosphere it is called a Meteoroid.

Meteors are pieces of rock glowing hot in the atmosphere. Before they hit the air, they were meteoroids. When they his the ground they are meteorites. Meteors are only found in the atmosphere, moving at incredible speeds.
They would burn up before they reach the Earth.

Unlike the Earth, the moon does not have an atmosphere to help protect it from meteors. When meteors enter the Earth's atmosphere, the resistance of the air causes friction and generates a tremendous amount of heat - so much so that most meteors are destroyed before they reach the ground. The moon does not have an atmosphere and therefore there is nothing stopping meteorites from bombarding the surface. Hence, the large number of impact craters on the moon.
