Earths Structure And Layers Questions
The different atmospheric layers and their characteristics are as follows:
1. Troposphere: This is the lowest layer of the atmosphere, extending from the Earth's surface up to about 8-15 kilometers. It is where weather phenomena occur, and temperature generally decreases with altitude.
2. Stratosphere: Above the troposphere, the stratosphere extends up to about 50 kilometers. It contains the ozone layer, which absorbs harmful ultraviolet radiation from the Sun. Temperature increases with altitude due to the presence of ozone.
3. Mesosphere: The mesosphere extends from the stratosphere up to about 85 kilometers. In this layer, temperature decreases with altitude, reaching extremely low temperatures. It is also where meteors burn up upon entering the Earth's atmosphere.
4. Thermosphere: Above the mesosphere, the thermosphere extends up to about 600 kilometers. Temperature increases with altitude due to the absorption of high-energy solar radiation. It is also the layer where the Northern and Southern Lights occur.
5. Exosphere: The outermost layer of the atmosphere, the exosphere extends from the thermosphere to the edge of space. It is composed of extremely low-density gases and gradually merges with the vacuum of space.
Each atmospheric layer has distinct characteristics and plays a crucial role in regulating Earth's climate and protecting life on the planet.
