The earth's atmosphere is divided into several layers, and each layer plays an important role. The first region extending about 10km upwards from the earth's surface is called the troposphere.
Ozone absorbs UV-B, which would otherwise damage our DNA, and the DNA of all surface dwellers on Earth (including phytoplankton in the oceans). This absorption of UV-B or more energetic light breaks the ozone down into an oxygen molecule and a single oxygen atom.here is also ozone in the lower troposphere, but the ozone layer in the stratosphere contains helpful ozone that blocks much of the ultraviolet radi â¦ ation. Without this layer, life on earth would be very difficult.
