Layers of the 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 we live, and it contains most of the Earth's weather.

Front

What is the Stratosphere?

Back

The Stratosphere is the second layer of the atmosphere, located above the Troposphere, and contains the ozone layer.

Front

What is the Mesosphere?

Back

The Mesosphere is the third layer of the atmosphere, where temperatures decrease with altitude and meteors burn up.

Front

What is the Thermosphere?

Back

The Thermosphere is the fourth layer of the atmosphere, characterized by high temperatures and where the Aurora Borealis occurs.

Front

What is the Exosphere?

Back

The Exosphere is the outermost layer of the atmosphere, where air is extremely thin and satellites orbit the Earth.

Front

What is the least dense layer of the atmosphere?

Back

The Exosphere is the least dense layer of the atmosphere.

Front

What gas makes up about 80% of the Earth's atmosphere?

Back

Nitrogen makes up about 80% of the Earth's atmosphere.

Front

What is the role of the ozone layer?

Back

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

Front

What happens to temperature as you go higher in the Troposphere?

Back

In the Troposphere, temperature decreases as altitude increases.
