An Introduction


INTODUCTION

The Earth’s atmosphere is a protective layer of gases that surrounds the planet, making life possible by providing oxygen, regulating temperature, and shielding us from harmful solar radiation.



It is composed mainly of nitrogen (78%) and oxygen (21%), along with trace amounts of other gases. The atmosphere is divided into five distinct layers—troposphere, stratosphere, mesosphere, thermosphere, and exosphere—each with unique characteristics and functions. These layers work together to support weather, communication, and environmental balance while also protecting Earth from space debris and harmful radiation. Understanding the layers of the atmosphere helps us appreciate their crucial role in sustaining life and maintaining Earth’s climate.
