What is the Earth's atmosphere made of? Which gases?

What's the difference between a comet and a meteor?
Meteors are made of rock and metals while comets are made from ice as well.

Gas planets: Jupiter, Saturn, Uranus, Neptune
Rocky planets: Mercury, Venus, Earth, Mars
Meteors burn up in the third layer of the atmosphere, the Mesosphere.
Once meteors come into contact with air on Earth, the pressure of the air against the speed of the meteor causes it to catch on fire and burn away.
There definitely are craters on the Earth. However, why can't we see them like we can see the ones on the Moon? BE SPECIFIC. What does Earth have that the Moon doesn't?
Earth has weathering, and the rain and wind erodes the craters down so we can't see them as well due to erosion.
Explain what conditions are like on the Moon. What is the atmosphere like? What is the weather like?
The Moon has no atmosphere. Because there is no atmosphere, there is no weather on the Moon either. Nothing happens on the Moon.
What are black holes?
Black holes are holes in space that suck everything into them and crush everything until matter turns into dust.
