This layer has an altitude up to 50 kilometers from the Earth. The temperature of the atmosphere is rising on the rise. At an altitude of about 50 kilometers from the surface. Temperatures around 10-20oC, which is why it is. Absorbs UV violet (UV) and infrared (IR) by ozone (O3), which found that the concentration of ozone in the ozone layer of about 1-5 ppm by volume are important to living things. It helps filter out harmful UV light. Sun up to 99%, making human survives the cancer
