The atmosphere is the layer of gases surrounding the Earth, essential for life. It comprises nitrogen, oxygen, and trace gases, regulating temperature, weather, and climate. It protects living organisms from harmful solar radiation and enables respiration, making it crucial for sustaining life on the planet.

The atmosphere is a vital layer of gases encircling the Earth, primarily composed of nitrogen (78%), oxygen (21%), and trace gases like argon and carbon dioxide. It plays a crucial role in regulating the planet’s temperature, weather, and climate, creating conditions suitable for life. The atmosphere acts as a protective shield against harmful solar radiation and facilitates essential processes such as respiration and photosynthesis. Divided into five main layers—troposphere, stratosphere, mesosphere, thermosphere, and exosphere—the atmosphere supports diverse ecosystems and influences various natural phenomena, from weather patterns to climate change, making it indispensable for sustaining life on Earth.
