Layers of the Earths Atmosphere

The Layer of the Earth that almost all of the weather occurs in

• thermosphere

• troposphere

• mesosphere

• stratosphere

This areas upper boundary is marked by the stratopause

• thermosphere

• troposphere

• mesosphere

• stratosphere

This area contains the ozone layer

• thermosphere

• troposphere

• mesosphere

• stratosphere

This areas temperature increase is a result of solar radiation by the concentration of ozone molecules

• thermosphere

• troposphere

• mesosphere

• stratosphere

As you go through the layers of the earths atmosphere the temperature.....

• decreases, increases, decreases and then increases

• increases, decreases, increases and then decreases

• increases, increases, decreases, increases

• decrease, increase, decrease, decrease

This area is where the air molecules are widely separated as the vacuum conditions of space are approached

• stratosphere

• troposphere

• thermosphere

• mesosphere

How far does the troposphere extend upwards?

• between 8km and 12km

• between 5km and 10km

• between 15km and 20km

• between 10km and 20km

What happens to temperature and air pressure with increased height in the troposphere?

• Temperature rises whilst air pressure falls

• Both Reduce

• Both Increase

• Temperature falls whilst air pressure increases

Why is the air unstable in the troposphere?

• the presence of cloud, pollution, water vapour and dust

• the presence of clouds and water vapour

• the presence of dust and clouds

• the presence of pollution

Which is the correct order of the Earths layers as we move away from the planet?

• troposphere, stratosphere, mesosphere, thermosphere

• stratosphere, troposphere, mesosphere, thermosphere

• thermosphere, mesosphere, troposphere, stratosphere

• troposphere, thermosphere, stratosphere, mesosphere
