A is for Air Pressure
Air PressureAir Pressure Air pressure is caused by the unequal Air pressure is caused by the unequal
heating of earth’s surface.heating of earth’s surface.
1. Low pressure is warm, moist air. It 1. Low pressure is warm, moist air. It raises and forms clouds. raises and forms clouds.

M is for Mountain Barriers
Mountain BarriersMountain Barriers Mountain Barriers create a phenomenon Mountain Barriers create a phenomenon
called the Orographic Effect or called the Orographic Effect or Rainshadow.Rainshadow.
The rainshadow helps create deserts The rainshadow helps create deserts
Ex. Sierra Nevada mountains in CA Ex. Sierra Nevada mountains in CA receive nice amounts of precipitation, receive nice amounts of precipitation, Las Vegas, NV is in the rainshadow Las Vegas, NV is in the rainshadow creating a desert climate.creating a desert climate.
Rainshadow EffectRainshadow Effect
Windward Side Leeward side
‘Wet’ side ‘Dry’ side
This rainshadow region in India was createdby the presence of the Western Ghats mountain
range, which block the monsoon(seasonal) winds from the west.
