Atmospheric Layers Diagram

Front

What is the tropopause?

Back

The tropopause is the boundary layer between the troposphere and the stratosphere, characterized by a temperature inversion and a decrease in temperature with altitude.

Front

What is altitude?

Back

Altitude refers to the height of an object or point in relation to sea level or ground level.

Front

What is the thermosphere?

Back

The thermosphere is the layer of the Earth's atmosphere above the mesosphere, where temperatures increase significantly with altitude due to solar radiation.

Front

What is the mesopause?

Back

The mesopause is the boundary between the mesosphere and the thermosphere, marking the transition where temperatures begin to rise again.

Front

What is the stratopause?

Back

The stratopause is the boundary layer between the stratosphere and the mesosphere, where temperature stops decreasing with altitude.

Front

What are the main layers of the atmosphere?

Back

The main layers of the atmosphere are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.

Front

What is the significance of the ozone layer?

Back

The ozone layer, located within the stratosphere, absorbs the majority of the sun's harmful ultraviolet radiation, protecting living organisms on Earth.

Front

How does temperature change with altitude in the troposphere?

Back

In the troposphere, temperature generally decreases with increasing altitude.

Front

What is the role of the stratosphere?

Back

The stratosphere contains the ozone layer and is where commercial jet aircraft typically fly, as it is more stable than the troposphere.

Front

What happens to air pressure as altitude increases?

Back

Air pressure decreases as altitude increases due to the thinning of the atmosphere.
