Review of Earth's Atmosphere

Front

What is the role of ozone in the stratosphere?

Back

Ozone in the stratosphere absorbs harmful ultraviolet (UV) radiation from the sun, protecting living organisms on Earth.

Front

What is the role of ozone in the troposphere?

Back

Ozone in the troposphere is a harmful pollutant that can cause respiratory problems and other health issues.

Front

What atmospheric layer do the Northern Lights (Auroras) appear in?

Back

The Northern Lights appear in the thermosphere.

Front

What is the exosphere?

Back

The exosphere is the outermost layer of Earth's atmosphere, extending from about 600 km above the Earth's surface to outer space.

Front

What is the mesosphere?

Back

The mesosphere is the third layer of Earth's atmosphere, located above the stratosphere and below the thermosphere, where temperatures decrease with altitude.

Front

What is the greenhouse gas produced by cellular respiration?

Back

Carbon dioxide is the greenhouse gas produced by cellular respiration.

Front

What is the primary component of Earth's atmosphere?

Back

Nitrogen is the primary component of Earth's atmosphere, making up about 78%.

Front

What is the function of the troposphere?

Back

The troposphere is the lowest layer of the atmosphere where weather occurs and where most of the Earth's air mass is located.

Front

What is the temperature trend in the stratosphere?

Back

In the stratosphere, temperature increases with altitude due to the absorption of UV radiation by ozone.

Front

What is the significance of the thermosphere?

Back

The thermosphere is significant for its high temperatures and is where the International Space Station orbits.
