How does the ozone layer differ from ozone at the surface of the earth?
Ozone molecules (O3) have three oxygen atoms. Ozone is found in two different layers in Earth's atmosphere. "Bad" ozone is found in the troposphere, the layer nearest the ground. ... Ozone in the stratosphere forms when a photon of ultraviolet "light" from the Sun strikes a normal oxygen molecule, breaking it apart.
Hi! Ozone is found in two different layers in Earth's atmosphere. "Bad" ozone is found in the troposphere, the layer nearest the ground. Tropospheric ozone is a harmful pollutant which forms when sunlight alters various chemicals emitted by humans. Part of the stratosphere is sometimes called the "ozone layer".
