Ozone Layer: How It Protects Us From Harmful UV Rays

The ozone layer in the Earth's atmosphere filters cancer-causing ultraviolet (UV) rays from the sun. The ozone layer is a region of the stratosphere that absorbs most of the Sun's UV radiation. It is located about 15 to 35 kilometers (9 to 22 miles) above the Earth's surface. The ozone layer protects life on Earth from harmful UV radiation, which can cause skin cancer, cataracts, and other health problems.
