What are the layers of the atmosphere?

Back

The atmosphere is divided into 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 we live. It extends from the Earth's surface up to about 8-15 kilometers.

What is the Stratosphere?

Back

The Stratosphere is the second layer of the atmosphere, located above the Troposphere. It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

What is the Mesosphere?

Back

The Mesosphere is the third layer of the atmosphere, located above the Stratosphere. It is the coldest layer, where temperatures can drop to -90 degrees Celsius.

Front

What is the Thermosphere?

Back

The Thermosphere is the fourth layer of the atmosphere, located above the Mesosphere. It is characterized by high temperatures and is 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. It is where satellites orbit the Earth.

Front

What is the function of the ozone layer?

Back

The ozone layer, located in the Stratosphere, absorbs the majority of the sun's harmful ultraviolet (UV) radiation.

Front

In which layer of the atmosphere do most weather events occur?

Back

Most weather events occur in the Troposphere.
