- About 10 to 12 km
- About 50 km
- About 80 to 85 km
- About 10,000 km
A weather balloon climbs above the clouds to about 35 km before it bursts. Which layer is it in then, Kira?
Use the picture in question 4.
- Mesosphere
- Stratosphere
- Troposphere
- Thermosphere
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 to the coldest on Earth
- It falls, as in the troposphere
- It rises
Brrr! Near the top of which layer is the coldest air in the atmosphere, Noah?
- Troposphere, as it touches the ground
- Thermosphere, as it is higher up
- Mesosphere: about −85 to −90 °C
- Exosphere, as it is the highest
Why does the stratosphere get warmer as you go higher in it, Pia?
- Heat from the mesosphere sinks into it
- Clouds trap heat there
- It is warmed by the ground below
- Ozone absorbs the Sun's ultraviolet light
