Acid Rain


Have you ever heard of Acid Rain? Well acid rain is very harmful to us humans and plants and animals. Acid Rain contains more acid then normal rain. Acid Rain is formed by the burning of a lot of sulfur,which produces sulfur oxides. Acid rain is very strong. It is so strong it can damage the surfaces of buildings and statues. Acid Rain harms ponds and lakes which is harmful to plants, amphibians, fish and insects so they can no longer survive. Some actions that humans can take to prevent Acid Rain are not burning so much coal so that there is not as much sulfur oxides in the air. That is what Acid Rain is, does and how you can prevent Acid Rain.

Earths Atmosphere

The Earths atmosphere is different from the moons and other planets in many ways. First off a planet with no atmosphere is not suitable for living things and earths atmosphere is. There might not be enough nitrogen for a person and we need nitrogen to be able to live. The moon is not suitable for us because there might not be all of the gases for us to live and we would not be used to it so more then likely we would die . The other way earths atmosphere differs from other planets or the moon is the temperature is does not stay in if there is no atmosphere, and since the earth does have an atmosphere the temperature does stay in. That is how Earths atmosphere is different from a planet that has no atmosphere or then the moons atmosphere.
