The first is most well known--the stratosphere contains high concentrations of ozone which shields the ground from many high energy photons that would otherwise contribute to plant damage and skin cancer. read more

Earth's atmosphere is important for several reasons: it supports the exchange of life-sustaining gases, filters sunlight, regulates temperature and even plays a role in the water cycle. The atmosphere contains five distinct layers. read more

If the ozone layer in the stratosphere is brought as it is on to the surface of the earth then it will form one inch thick layer. Depletion of ozone layer has become a major issue recently. Loss of ozone layer will lead to many human health problems. read more
