Layers of the Atmosphere

Front

What are the layers of the atmosphere in order from the Earth's surface to outer space?

Back

1. Troposphere 2. Stratosphere 3. Mesosphere 4. Thermosphere 5. Exosphere

Front

What is the primary characteristic of the Troposphere?

Back

It is the lowest layer of the atmosphere where weather occurs and where most of the mass of the atmosphere is found.

Front

What is the significance of the Stratosphere?

Back

It contains the ozone layer, which absorbs and scatters ultraviolet solar radiation.

Front

What happens to temperature as you move up through the Mesosphere?

Back

Temperature decreases with altitude in the Mesosphere.

Front

What is the role of the Thermosphere?

Back

It is characterized by a significant increase in temperature with altitude and is where the auroras occur.

Front

What is the Exosphere?

Back

The outermost layer of the atmosphere, where atmospheric particles are so sparse that they can travel hundreds of kilometers without colliding with one another.

Front

What does 'Tropo' mean in the context of the Troposphere?

Back

It means 'change', indicating the layer where weather changes occur.

Front

At what altitude does the Troposphere typically extend to?

Back

It extends from the Earth's surface up to about 8 to 15 kilometers (5 to 9 miles) depending on the latitude.

Front

What is the boundary between the Troposphere and the Stratosphere called?

Back

The tropopause.

Front

What is the temperature trend in the Stratosphere?

Back

Temperature increases with altitude due to the absorption of UV radiation by the ozone layer.
