When the sun’s UV rays come in contact with CFCs, the chlorine atoms come loose. These chlorine atoms wander around the atmosphere until they meet up with ozone molecules. The chlorine atom and one of the oxygen atoms of ozone combine, leaving behind diatomic, or molecular, oxygen. When a free oxygen atom contacts this chlorine-oxygen compound, the two oxygen atoms combine to form molecular oxygen, and the chlorine goes off to devastate more ozone molecules. Molecular oxygen, unlike ozone molecules, cannot keep UV rays from reaching the Earth's surface. The U.S. Environmental Protection Agency estimates that one atom of chlorine can destroy as many as 100,000 molecules of ozone. In 1974, M. J. Molina and F. S. Rowland published a paper outlining how CFCs broke down ozone molecules in the atmosphere.

Answer from: Quest

increase soil erosion reduce soil erosion

cattle grazing hydroseeding

deforestation contour plowing

planting vegetation

plant roots basically hold the top soil

together and stop soil erosion because

in such situation top soil is not removed

during flood but cattle grazing causes

soil erosion because cattle consume the

grasses and herbs and top soil is exposed.

same situation occurs because of

deforestation, the trees and plants are cut

down to expose top soil which causes soil

erosion
