Air containing water vapour cools as it rises over a mountain. This can cause the vapour to condense and form rain.

As moist air rises up the windward slope of a mountain range, it expands and cools. As air cools, the rate of evaporation decreases while the rate of condensation increases. The result is an increase in the number of water droplets in the air. These droplets can combine to form rain drops. As more water vapour condenses, the cloud drops become larger. When they are too heavy to remain suspended in the atmosphere, they fall to the ground as rain. In colder temperatures (below freezing), water vapour condenses into snow.

As an air mass moves first upslope and then downslope over a mountain. What happens to air's moisture and heat content?
look in ch. 31 of your textbook
What will happen to the air if you climb a mountain?
As you climb the mountain, the air pressure decreases. The temperature also drops.
How does orographic precipitation occur?
warm moist air is force to rise over a mountain range, as the air moves up it will expand, cools and condenses then precipitation will occur.This is clearly seen in the eastern part of South Africa
What kind of a front forms where a warm air mass moves over a cold air mass?
humid
What do you call it when warm air over land rises and cool air from water moves in?
A sea breeze
What will happen if a high humidity air mass located over an ocean moves inland an up a mountain slope and why?
it will rain
Why do clouds forms as air moves over a mountain?
It cause rain
What should a person expect to happen to the air pressure as she moves from the base of the mountain to the top of the mountain?
The air pressure will decreases as you go up the mountain. Density and air mass goes down too. Hope this helps!
When air passes over a Mountain dry air moves downward on the opposite side creating what?
warmth and evaporation
What is the formula for the change of temperature of an air mass as it passes Over a mountain and as it moves into a Leeward Valley?
The answer is 7
As an air mass moves first upslope and then downslope over a mountain. What happens to air's moisture and heat content?

What is air that moves down from the mountain to the valley?
bald eagle
When air moves over a mountain range?
"Heavy rains on the west side of the mountains and deserts on the east side" Moving air over mountains is called lee waves. See related link.
What happen to the speed of sound as it moves from water to air?
It will slow - sound moves faster in water than in air.
What will happen to the air if you climb a mountain?
As you climb the mountain, the air pressure decreases. The temperature also drops.
What happens to a cold air when a warm air moves into a region?
the warm air rises up and moves over the cold air that is already there.
Why does air move up the mountain during the day and down at night?
because the air warms as it moves down
