How many layers does the atmosphere have?

Back

The atmosphere has five main layers: Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

Front

What is the Troposphere?

Back

The Troposphere is the lowest layer of the atmosphere where weather occurs and where most living organisms exist.

Front

What is the Stratosphere?

Back

The Stratosphere is the second layer of the atmosphere, above the Troposphere, and contains the ozone layer which protects us from UV radiation.

Front

What is the Mesosphere?

Back

The Mesosphere is the third layer of the atmosphere, located above the Stratosphere, and is where the coldest temperatures are found.

Front

What is the Thermosphere?

Back

The Thermosphere is the fourth layer of the atmosphere, characterized by high temperatures and where the auroras occur.

Front

What is the Exosphere?

Back

The Exosphere is the outermost layer of the atmosphere, where the atmosphere thins out and merges with outer space.

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 role does the atmosphere play in weather?

Back

The atmosphere is crucial for weather patterns, as it contains the air and moisture that drive weather systems.

Front

What is air pressure?

Back

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