Most ozone resides in the stratosphere (a layer of the atmosphere between 10 and 40 km above us), where it acts as a shield to protect Earth's surface from the sun's harmful ultraviolet radiation.
Quick Answer. Earthâs 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. The layer closest to the surface is called the troposphere, and it provides the majority of the planetâs oxygen. This layer is also responsible for weather, including rain, which protects Earth's inhabitants from drought and starvation.
