Earth's Atmosphere

Unlike the moon Earth as a very protective atmosphere. Earth been impacted by the same amount of meteorites as the moon , but Earth has an atmosphere so the crater washed away in a short time. On the moon though a crater can stay on the surface of the moon for 4 billion years. Earth's atmosphere can also keep heat in it and keep heat out which makes it possible for humans to live on Earth. The ozone layer protects Earth and the life on it from ultra violet rays. The moon can't keep its own heat in or out without an atmosphere so the temperatures on the moon are very extreme. Earth can also hold gases in its atmosphere. This makes it possible for human existence. Earth's atmosphere is suitable for living things it can hold in gases and heat, therefore it is different from the moon.
