Layers of the Atmosphere

Front

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 extends from the Earth's surface up to about 8-15 kilometers.

Front

What is the Stratosphere?

Back

The Stratosphere is the second layer of the atmosphere, located above the Troposphere, and extends from about 15 to 50 kilometers. It contains the ozone layer.

Front

What is the Mesosphere?

Back

The Mesosphere is the third layer of the atmosphere, located above the Stratosphere, and extends from about 50 to 85 kilometers. It is where most meteors burn up upon entering the atmosphere.

Front

What is the Thermosphere?

Back

The Thermosphere is the fourth layer of the atmosphere, extending from about 85 to 600 kilometers. 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, extending from about 600 kilometers to 10,000 kilometers. It is where the atmosphere transitions into outer space.

Front

What is the main characteristic used to divide the atmosphere into layers?

Back

The atmosphere is divided into layers primarily based on changes in air temperature.

Front

What happens in the Troposphere?

Back

The Troposphere is where all weather phenomena occur, including clouds, rain, and storms.

Front

What is the ozone layer and where is it located?

Back

The ozone layer is located in the Stratosphere and protects the Earth from harmful ultraviolet (UV) radiation.

Front

What are auroras and where do they occur?

Back

Auroras, also known as northern and southern lights, occur in the Thermosphere due to the interaction of solar wind with the Earth's magnetic field.
