Layers of Atmosphere

Front

What are the layers of the atmosphere?

Back

The atmosphere is divided into five main layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

Front

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.

What is the Stratosphere?

Back

The Stratosphere is the second layer of the atmosphere, located above the Troposphere. It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

What is the Mesosphere?

Back

The Mesosphere is the third layer of the atmosphere, located above the Stratosphere. It is where most 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 outermost layer of the atmosphere, where the atmosphere thins out into space. It is where satellites orbit the Earth.

Front

How does temperature change with altitude in the Troposphere?

Back

In the Troposphere, temperature decreases with altitude, meaning it gets colder as you go higher.

Front

What is the role of the ozone layer?

Back

The ozone layer, located in the Stratosphere, protects life on Earth by absorbing harmful ultraviolet (UV) radiation from the sun.

Front

What is air pressure?

Back

Air pressure is the force exerted by the weight of air above a given point. It decreases with altitude.

What is the greenhouse effect?

Back

The greenhouse effect is the process by which certain gases in the atmosphere trap heat, keeping the Earth warm.
