Layers of the Atmosphere

Front

What is the troposphere?

Back

The troposphere is the lowest layer of Earth's atmosphere, where weather occurs and where we breathe.

Front

What happens to temperature as altitude increases in the troposphere?

Back

The temperature decreases with altitude in the troposphere.

Front

Which layer of the atmosphere is the highest?

Back

The thermosphere is the highest layer of the atmosphere.

Front

What is the mesosphere known for?

Back

The mesosphere is known for being the layer where meteors burn up upon entering Earth's atmosphere.

Front

What is the main characteristic of the thermosphere?

Back

The thermosphere has extremely high temperatures, but the air is too thin to transfer heat effectively.

Front

What is the role of the ozone layer?

Back

The ozone layer absorbs harmful ultraviolet (UV) radiation from the sun.

Front

In which layer do most weather phenomena occur?

Back

Most weather phenomena occur in the troposphere.

Front

What is the exosphere?

Back

The exosphere is the outermost layer of the atmosphere, where the atmosphere transitions into outer space.

Front

What is the ionosphere?

Back

The ionosphere is a region of the atmosphere that is ionized by solar radiation and is important for radio communication.

Front

How does the temperature change in the stratosphere?

Back

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