Use the picture in question 4.
- Exosphere (layer E)

A weather balloon carries a thermometer up through the stratosphere. What happens to the air temperature around it, Milo?
- It stays at 0 °C
- It falls, as in the troposphere
- It rises
- It falls to the coldest on Earth
Why does the stratosphere get warmer as you go higher in it, Pia?
- Clouds trap heat there
- It is warmed by the ground below
- Ozone absorbs the Sun's ultraviolet light
- Heat from the mesosphere sinks into it
