Earth's Atmosphere

The Earth and the Moon or a planet with no atmosphere they have a very different atmosphere. Earth's atmosphere is able to hold life, and a suitable temperature for life. With no atmosphere there is no stable temperature, when a meteoroid is headed for the planet with no atmosphere. The meteoroid won't burn up coming through the atmosphere, so it will hit the planet and make a crater. Also with no atmosphere land marks such as a foot print will last longer because there is no erosion or weather to wash it away or destroy it. Earth's atmosphere holds solids, liquids, and gases in it, also the atmosphere will burn up any meteorites that try to hit Earth. That's why Earth is so much different from the Moon or any other planets with no atmosphere.
