How is good ozone formed
Web28 sep. 2024 · Ozone occurs in two layers of the atmosphere. The layer closest to the Earth’s surface is the troposphere. Here, groundlevel or “bad” ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation. It is a main ingredient of urban smog. The troposphere generally extends to a level about 6 miles up ... WebIn the stratosphere, ozone is created primarily by ultraviolet radiation. When high-energy ultraviolet rays strike ordinary oxygen molecules (O 2 ), they split the molecule into two single oxygen atoms, known as atomic oxygen. A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone.
