Earths Atmosphere

Earth is a very unique planet. Its the only planet that we know of that could with stain life. Most of this reason why the Earth is so unique is because of it's atmosphere. Because of earths atmosphere it has a stable weather meaning that it doesn't get to hot or to cold because the atmosphere holds heat within the earth and it keeps heat out from entering earth. It also keeps earth alive. Earth is constantly changing meaning that if you leave a foot print in dirt it would disappear over time. Unlike the moon or other planets without a atmosphere the foot print will be their forever. Also the most important thing about earths atmosphere is that it protects earth from falling debrea or asteroids or comments. When a objects enters earths atmosphere it causes a lot of friction on the object causing it to burn up the object before it the object even gets close to earths atmosphere. Because of earths atmosphere earth is very different and unique from other planets or moons in space.
