3
Q
Explain continentality
A
Air loses moisture across land and can’t become moist again as there’s no water
4
Q
Explain topography
A
Moist air moves up the windward side and cools and condenses
5
Q
Explain cold ocean currents

Cold moisture less air flows into land displacing warm air and preventing convection currents
6
Q
