Understanding Ozone Depletion: Causes and Impact

The ozone layer, found in the stratosphere at 15 to 40 km altitude, plays a crucial role in absorbing harmful ultraviolet radiation. However, due to the use of Chlorofluorocarbons (CFCs), the ozone layer has been depleted, leading to the formation of the ozone hole. This depletion is caused by chemi

Understanding Ozone Depletion and Its Impact on the Environment

The stratosphere contains a vital layer of ozone that shields the Earth from harmful UV radiation. However, human activities, particularly the use of chlorofluorocarbons (CFCs), have led to the depletion of this protective ozone layer, especially over the poles. This thinning of ozone poses signific

Understanding Earth's Atmosphere Composition and Layers

Earth's atmosphere is primarily composed of nitrogen and oxygen, with other gases like argon, CO2, and water vapor making up the remaining percentage. While the levels of nitrogen and oxygen remain constant, variable gases like water vapor fluctuate based on location and time. CO2 levels have been i
