Layers

The atmosphere is divided into five distinct layers, each characterized by changes in temperature and composition. The troposphere is the lowest layer, extending from the Earth’s surface up to about 8-15 kilometers, where weather phenomena occur. Above it lies the stratosphere, which contains the ozone layer that shields Earth from UV radiation. This layer is more stable and less turbulent than the troposphere. Next is the mesosphere, where temperatures drop significantly, and meteors often burn up upon entry. The thermosphere is characterized by high temperatures, which can soar above 1,500°C; however, this heat isn’t felt due to the thin air. Finally, the exosphere gradually fades into space, with extremely low density. Each layer plays a vital role in the Earth’s climate system, influencing everything from weather patterns to satellite operations.
