How many layer in the atmosphere?

Question

Answer

Atmosphere has 5 layers.These layers are the troposphere, stratosphere, mesosphere and thermosphere. A further region at about 500 km above the Earth's surface is called the exosphere.

Answer

There are 5 layers in Atmosphere:
Troposphere
Stratosphere
Mesosphere
Thermosphere
Exosphere

Answer

Layers of the Atmosphere
The Earth's atmosphere is divided into five layers based on temperature and composition. Each layer plays a unique role in protecting and supporting life on our planet.

Troposphere
- The troposphere is the lowest layer of the atmosphere, extending from the Earth's surface up to about 10 kilometers.
- This layer is where all weather events occur and contains the majority of the Earth's clouds and precipitation.
- Temperature decreases with altitude in the troposphere.

Stratosphere
- The stratosphere lies above the troposphere and extends up to about 50 kilometers above the Earth's surface.
- This layer contains the ozone layer, which absorbs harmful ultraviolet radiation from the sun.
- Temperature increases with altitude in the stratosphere due to the absorption of solar radiation by the ozone.

Mesosphere
- The mesosphere is the third layer of the atmosphere, located above the stratosphere and extending up to about 85 kilometers.
- This layer is where most meteorites burn up upon entering the Earth's atmosphere.
- Temperature decreases with altitude in the mesosphere.

Thermosphere
- The thermosphere is the second-highest layer of the atmosphere, extending up to about 600 kilometers above the Earth's surface.
- This layer experiences high temperatures due to the absorption of solar radiation.
- The International Space Station orbits within the lower thermosphere.

Exosphere
- The exosphere is the outermost layer of the Earth's atmosphere, beginning around 600 kilometers above the surface and extending into space.
- This layer consists of very low densities of gas molecules and transitions into the vacuum of space.
- Satellites orbit within the exosphere.
