Layers of the Atmosphere

What sphere do we live in?

• Thermosphere

• Mesosphere

• Stratosphere

• Troposphere

How does the atmosphere protect life on Earth?

• It blocks harmful rays from the sun

• It keeps our planet the right temperature

• It provides oxygen to breathe

• All of these protect life on Earth

What would Earth be like without an atmosphere?

• There would be no life

• There would be no air

• More radiation from the sun would harm the planet

• All of these are true

The uppermost layer is the

• thermosphere.

• stratosphere.

• mesosphere.

• exosphere.

Why are the thermosphere and exosphere the warmest of the atmospheric layers?

• because of the gases trapped in these layers

• because they are closest to the Sun

• because the underlying mesosphere keeps the warm air there

• because the air pressure is too great

As you move up in the atmosphere, what happens to the air pressure?

• It increases

• It decreases

• It stays the same

Which two describe the layer: Troposphere

• Layer closest to earth

• The hottest layer

• Layer farthest from earth

• Where weather occurs
