What is troposphere?

300
The process of water molecules in the air is changed into liquid water.

What is condensation?

300

The amount of water vapour in the air compared to how much it can hold in total.

What is relative humidity?

300

Weather with a low pressure air mass often creates these. 

What is clouds?

300

The earth's rotation causes this - which causes wind to deflect to the side. 

What is the Coriolis effect?
