Layers of Atmosphere Review

The atmosphere is

• the layer in which weather occurs
• the layer that contains the ozone layer
• the layer of water in the oceans
• the layer of gases that surrounds Earth

Earth's atmosphere is important to living things because it

• contains dust and other particles
• is very thin compared to the size of Earth
• provides all the gases that living things need to survive
• maintains a constant relative humidity

The layer in our atmosphere in which weather occurs is the

• troposphere
• stratosphere
• mesosphere
• exosphere

The ozone layer protects living things on Earth from

• visible light
• UV radiation
• carbon dioxide

Which layer extends from the top of the troposphere to the bottom of the mesosphere?

• stratosphere
• meteors
• troposphere
• thermosphere

Which layer protects Earth from being hit by most meteors?

• troposphere
• stratosphere
• mesosphere
• thermosphere

In which layer does the energy from the sun strike gas molecules, causing them to glow (Aurora Borealis)?

• Troposphere
• Stratosphere
• Mesosphere
• Thermosphere

Which of the following is the correct order for the layers of Earth's atmosphere, starting at Earth's surface?

• stratosphere, troposphere, mesosphere, thermosphere
• thermosphere, stratosphere, troposphere, mesosphere
• troposphere, stratosphere, mesosphere, thermosphere
• mesosphere, thermosphere, stratosphere, troposphere

Which layer of Earth’s atmosphere is the one farthest from the surface of the Earth?
