Earth's Atmosphere Class 12: Definition, Layers, Composition, And Diagram - Laws Of Nature

The Earths atmosphere is a vital layer of gases that surrounds our planet, extending up to 10,000 kilometers. It contains a mix of gases, including nitrogen, oxygen, and carbon dioxide, which provide essential functions such as regulating the climate, protecting against harmful radiation, and providing oxygen for breathing. The atmosphere is divided into five layers based on temperature, altitude, and composition: troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
