4. Atmosphere

4. Atmosphere

The atmosphere is a vital layer of gases surrounding Earth, essential for maintaining life by providing oxygen, regulating climate, and protecting against harmful solar radiation. Its structure comprises five distinct layers, each playing specific roles in weather, climate, and communication. Various factors such as latitude, altitude, and distance from the sea significantly influence weather conditions and climatic patterns across the globe.
