What is the Troposphere?

Back

The Troposphere is the lowest layer of the atmosphere, where weather occurs and where we live. It extends from the Earth's surface up to about 8-15 kilometers.

Front

What is the Stratosphere?

Back

The Stratosphere is the second layer of the atmosphere, located above the Troposphere. It contains the ozone layer, which protects us from harmful UV radiation.

Front

What is the Mesosphere?

Back

The Mesosphere is the third layer of the atmosphere, located above the Stratosphere. It is where meteors burn up upon entering the Earth's atmosphere.

Front

What is the Thermosphere?

Back

The Thermosphere is the fourth layer of the atmosphere, characterized by high temperatures and the presence of the ionosphere, which is important for radio communication.

Front

What is the Exosphere?

Back

The Exosphere is the fifth layer of the atmosphere, where the atmosphere thins out and merges with outer space. It is where satellites orbit the Earth.

Front

What is the Ozone Layer?

Back

The Ozone Layer is a region within the Stratosphere that contains a high concentration of ozone (O3) and protects the Earth from harmful ultraviolet (UV) radiation.

Front

What is the role of the Ionosphere?

Back

The Ionosphere is a part of the Thermosphere that contains charged particles and is important for radio wave propagation.

Front

What happens to temperature in the Troposphere as altitude increases?

Back

In the Troposphere, temperature decreases with increasing altitude.
