Layers of the Atmosphere

• Troposphere


• Stratosphere


• Mesosphere


• Thermosphere

Troposphere
The troposphere is the lowest layer of the atmosphere, extending from the earth's surface up to about 8-15 kilometers. It is where all weather occurs, including clouds, rain, and snow. The temperature in the troposphere decreases as altitude increases.

Stratosphere
The stratosphere is the second layer of the atmosphere, extending from the top of the troposphere to about 50 kilometers. The ozone layer is found in the upper part of the stratosphere, which absorbs harmful ultraviolet radiation from the sun. The temperature in the stratosphere increases as altitude increases.

Mesosphere
The mesosphere is the third layer of the atmosphere, extending from the top of the stratosphere to about 85 kilometers. It is the coldest layer of the atmosphere, with temperatures dropping as low as -100°C. Meteoroids burn up in this layer, producing shooting stars.

Thermosphere
The thermosphere is the uppermost layer of the atmosphere, extending from the top of the mesosphere to the edge of space. It is the hottest layer of the atmosphere, with temperatures reaching up to 2,000°C. The auroras occur in the thermosphere due to the interaction between the Earth's magnetic field and charged particles from the sun.

In conclusion, the atmosphere is divided into four layers, each with unique characteristics and functions. The troposphere is where all weather occurs, the stratosphere contains the ozone layer, the mesosphere is the coldest layer, and the thermosphere is the hottest layer. Understanding the layers of the atmosphere is crucial for understanding Earth's climate and weather patterns.
