I'm trying to find out more about the ozone layer. Can you tell me more about it?

The ozone layer is a region of the stratosphere that absorbs most of the ultraviolet radiation from the sun, protecting life on Earth from harmful UV rays. It is made up of three layers of gas, each with its own distinct properties and functions. The first layer is called the troposphere and is located between 10-12 km above the surface of the earth. This layer contains the majority of the ozone in our atmosphere. The second layer is called the mesosphere, and is located between 12-50 km above the surface of the earth. This layer has a lower concentration of ozone than the troposphere, but still absorbs some UV radiation. The third layer is called the thermosphere, and is located between 50-500 km above the surface of the earth. This layer contains very little ozone, and so does not absorb much UV radiation.
