Atmospheric environment

Atmospheric Environment refers to the layer of gases surrounding the Earth known as the atmosphere. It plays a crucial role in supporting life by providing oxygen, absorbing ultraviolet solar radiation, and regulating temperature.

Composition

The atmospheric environment is composed primarily of nitrogen (78%) and oxygen (21%), with small amounts of argon, carbon dioxide, and other trace gases. The atmosphere also contains water vapor, which affects weather and climate.

Layers

The atmosphere is divided into five main layers: the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Each layer has unique characteristics and plays a different role in the atmospheric environment.

Role in Climate

The atmospheric environment plays a significant role in the Earth's climate. It absorbs and redistribits solar energy, which influences temperature patterns and weather phenomena. Changes in the atmospheric environment, such as increases in greenhouse gases, can lead to climate change.

Human Impact

Human activities, such as burning fossil fuels and deforestation, have significant impacts on the atmospheric environment. These activities increase the concentration of greenhouse gases in the atmosphere, leading to global warming and climate change.

Protection and Conservation

Efforts to protect and conserve the atmospheric environment include reducing greenhouse gas emissions, promoting renewable energy, and implementing policies to mitigate climate change.
