How much uv does the ozone layer absorb
Nettet25. jul. 2024 · The "ozone layer," approximately 6 through 30 miles above the Earth's surface, reduces the amount of harmful UV radiation reaching the Earth's surface. … NettetThe ozone gas can be found in two different regions of the Earth's atmosphere. The majority of the ozone (about 97%) is concentrated in the stratosphere at an altitude of 15 to 55 km. This stratospheric ozone provides an important service to life on the Earth as it absorbs harmful ultraviolet radiation.
