The atmosphere supports life on Earth by protecting it from dangerous electromagnetic radiation, by creating and controlling weather and climate and by providing the gases that plants and animals need to breathe. The atmosphere is composed of the troposphere, the tropopause, the stratosphere, the mesosphere and the ionosphere.


Without an atmosphere, the Earth would be a rocky planet with no oceans, clouds or life. The mix of gases and conditions in the Earth's atmosphere make life possible. Plants and animals need the gases in the air to survive, and the protection the atmosphere provides helps sustain life as well.


Life is able to exist on Earth because of a small number of reasons. It has the right climate, water is abundant, its air is breathable, it receives the perfect amount of energy from the Sun and is able to protect itself from the Sun's harmful rays and particles because of its atmosphere and magnetic field.


(Without the atmosphere, the average temperature on Earth would be below freezing!) The atmosphere also protects living things on Earth from the sun's harmful ultraviolet radiation. A thin layer of gas called ozone high up in the atmosphere filters out these dangerous rays. The atmosphere also helps to sustain life of Earth.


The Earth is unique in our solar system because it is the only planet that has life on it. It is the only planet in a viable position to support life (other than bacteria), the only planet with ...

Earth’s atmosphere protects life on the surface by filtering deadly ultraviolet radiation, destroying most meteors that pass through it and retaining heat. The atmosphere also provides oxygen to humans and carbon dioxide to plants. The atmosphere consists of five layers and is approximately 60 miles thick.


Life affects the climate system and in turn, the climate dictates where and how species can survive. Life affects the composition of the atmosphere and therefore the climate because different life forms take in and release gases like carbon dioxide, methane and oxygen at different rates.
