Atmosphere Paragraph

Earth's atmosphere makes it very different from the moon and all the other planets in the solar system in a few different ways. First, hundreds of craters cover the moon from meteoroids. There is no atmosphere to stop them. On Earth however, there are far less meteroids that strike. The reason that so few meteroids make it to the surface of Earth is the atmosphere. When the meteroid enters the atmosphere, the friction of the object and the atmosphere causes the object to burn up. The evidence of the ones that do strike doesn't last very long. The weather and climate change on Earth wears away the evidence of the impact. Earth is also extreamly different from the other planets because of its atmosphere. Earths atmosphere. On planets lacking an atmosphere, the sun bakes them allowing nothing to live. On Earth there is a steady temperature deue to the atmosphere. On the moon and other planets they are extreamly hot when the sun is touching them and extreamly cold when the sun isn't facing them. Finally, on Earth thre is liquid water because the atmosphere protects it from harsh temperatures that would evaporate or freeze the water. On the moon and other solar system planets, the temperatures an way to extreame for water to take its liquid form. Earth is very unique.
