Front

What characteristic of the troposphere decreases as altitude increases?

Back

Both air pressure and temperature decrease as altitude increases in the troposphere.

Front

Where does the aurora occur, which is caused by the collision of energetic charged particles with atoms in the high altitude atmosphere?

Back

The aurora occurs in the thermosphere.

Front

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

Back

The troposphere is the layer of the atmosphere closest to Earth's surface.

Front

Which layer of the atmosphere contains the ozone layer that absorbs and scatters solar ultraviolet radiation?

Back

The stratosphere contains the ozone layer.

Front

At what altitude does the thermosphere start?

Back

The thermosphere starts at an altitude of 80 km (50 miles) above Earth.

Front

What is the primary function of the ozone layer in the stratosphere?

Back

The primary function of the ozone layer is to absorb and scatter solar ultraviolet radiation.

Front

What happens to air pressure as you ascend through the atmosphere?

Back

Air pressure decreases as you ascend through the atmosphere.

Front

What is the temperature trend in the troposphere as altitude increases?

Back

The temperature generally decreases as altitude increases in the troposphere.

Front

What is the significance of the thermosphere in relation to space weather?

Back

The thermosphere plays a significant role in space weather, as it is where charged particles from the sun interact with the Earth's atmosphere.

Front

What are the main layers of the atmosphere in order from the Earth's surface upward?

Back

The main layers of the atmosphere from the Earth's surface upward are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
