What is the atmosphere?

The atmosphere is the layer of gases surrounding Earth.

Name the main layers of the Earth's atmosphere.

The main layers are Troposphere, Stratosphere, Mesosphere, Thermosphere, and Exosphere.

Which layer of the atmosphere is closest to Earth?

The Troposphere is the closest layer to Earth.

Why is the Ozone layer important?

The Ozone layer protects Earth from harmful ultraviolet (UV) radiation from the sun.

In which layer does weather occur?

Weather occurs in the Troposphere.

What is the highest layer of Earth's atmosphere?

The Exosphere is the highest layer.

Which layer contains the most oxygen?

The Troposphere contains the most oxygen.

How does the temperature change in the Stratosphere?

The temperature increases with altitude in the Stratosphere.

What happens in the Mesosphere?

The Mesosphere is where most meteoroids burn up upon entry.

Which layer has the Aurora Borealis?

The Aurora Borealis occurs in the Thermosphere.

What causes weather changes in the Troposphere?

Weather changes are caused by the movement of air masses, humidity, temperature, and pressure differences.

Why do planes fly in the Stratosphere?

Planes fly in the Stratosphere to avoid weather disturbances and turbulence found in the Troposphere.

What gases primarily make up the atmosphere?

The atmosphere mainly consists of Nitrogen, Oxygen, Argon, and Carbon Dioxide.

How does air pressure change with altitude?

Air pressure decreases as altitude increases.

What role does the Exosphere play?

The Exosphere is where atmospheric particles fade into space and satellites orbit Earth.
