How does atmosphere help us?

 

Atmosphere is important for life on Earth and helps us in a number of ways. Some of the ways are:

 

 

  • Gases in the atmosphere hold in heat. The Earth's average temperatures would fall below the freezing point of water without atmospheric gases to hold enough heat. Atmosphere absorbs the heat from the sun and keeps the heat inside the atmosphere, helping the Earth stay warm. It also keeps the overall temperature of the Earth fairly steady. 

 

  • There is a lot of space debris that comes towards Earth every day. The atmosphere protects us from this space debris, or meteoroids, that enter the atmosphere from space. These pieces of rock burn up when they enter the atmosphere. The ones that don’t burn up completely reach us, but in a much smaller form, and they are called meteorites.

 

  • The atmosphere also acts as a filter, keeping out ultraviolet radiation. Excessive exposure to ultraviolet radiation can be harmful to living things and causes sunburn.
