Effect of latitude on rainfall

Question 1

What form of gas does air contain?

Answer 1

Air contains water in the form of a gas called water vapour. For the rain to fall, the water vapour needs to condense, or change back into liquid, and form clouds.

Question 2

When does this happen?

Answer 2

This happens when rising air cools. At certain latitudes, air rises; at other latitudes, air sinks down toward the Earth from high above it.

Question 3

Where is there more rain?

Answer 3

There is more rain at latitudes with rising air than at latitudes with sinking air.
