CLMS Layers of Atmosphere Vocab

Front

What is the exosphere?

Back

The exosphere is the 5th layer of the atmosphere, located farthest from Earth, where the atmosphere thins out and merges with outer space.

Front

What happens to temperature in the stratosphere as altitude increases?

Back

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

Front

Which layer of the atmosphere is closest to Earth?

Back

The troposphere is the closest layer to Earth, where weather occurs and life exists.

Front

What happens to temperature in the thermosphere as altitude increases?

Back

In the thermosphere, temperature increases significantly with altitude, reaching up to 2,500 °C (4,500 °F) or more.

Front

What does the prefix 'Tropo-' mean?

Back

The prefix 'Tropo-' means 'change' or 'turn', indicating the layer where weather changes occur.

Front

What is the mesosphere?

Back

The mesosphere is the 3rd layer of the atmosphere, located above the stratosphere and below the thermosphere, where temperatures decrease with altitude.

Front

What is the thermosphere?

Back

The thermosphere is the 4th layer of the atmosphere, characterized by high temperatures and the presence of the ionosphere.

Front

What is the ozone layer?

Back

The ozone layer is a region within the stratosphere that absorbs most of the Sun's harmful ultraviolet radiation.

Front

What is the significance of the troposphere?

Back

The troposphere is significant because it contains most of the Earth's weather and is where we live.

Front

What is atmospheric pressure?

Back

Atmospheric pressure is the force exerted by the weight of air above a given point, decreasing with altitude.
