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

Which layer of the atmosphere is the outermost?

Back

Exosphere.

Front

What is the function of the ozone layer?

Back

It absorbs ultraviolet light rays, protecting living organisms on Earth.

Front

What happens to temperature in the troposphere as altitude increases?

Back

The temperature decreases as you go higher in the troposphere.

Front

What is the composition of the troposphere?

Back

The troposphere is composed of approximately 78% nitrogen, 21% oxygen, and 1% other gases.

Front

Which layer of the atmosphere is closest to the Earth's surface?

Back

Troposphere.

Front

What is the Stratosphere known for?

Back

The Stratosphere contains the ozone layer and is where commercial jets typically fly.

Front

What is the temperature trend in the Stratosphere?

Back

In the Stratosphere, temperature increases with altitude due to the absorption of UV radiation by the ozone layer.

Front

What is the Mesosphere?

Back

The Mesosphere is the layer above the Stratosphere where temperature decreases with altitude and is where most meteors burn up.

Front

What is the Thermosphere?

Back

The Thermosphere is characterized by very high temperatures and is where the auroras occur.
