Is there a lot of humidity when air mass rises up a mountain side?

When an air mass rises up a mountain side the air cools as it rises. Cool air can not hold as much moisture as warm air so the humidity will increase until the dew point is reached whereupon the water will come out of the air (as mist/clouds and rain/snow).
On the other side of the mountain the air comes down again and as it has lost its water it is now very dry this side of the mountain is called a rain shadow.

How do convection currents form downdrafts in deserts near tall mountain ranges?
Warm air expands and rises from the base on one side of the mountain. It cools and contracts in the clouds above the mountain and sinks back down but on the desert side of the mountains. This way both sides of the mountain are heated properly.
Which side of a mountain would a desert most likely form?
the eastern side because there is less rain/moisture.
What portion of a mountain recieves little precipitation?
The windward side (as opposed to the leeward side). This is the side facing the prevailing wind, where the air is forced up the mountain where it must cool, condense, and precipitate out its moisture. As it passes the mountain it will sink, whereby it compresses and warms, which is not conducive to precipitation or even clouds.
What is another name for the orographic effect?
The orographic effect occurs when winf from over the ocean passes over a mountain and the lack of rain creates a desert on the other side.
What is the initial transfer of energy that accelerates the rock down the side of the mountain?
Potential energy is converted into kinetic energy
What happens when warm air rises and is replaced by cooler air?
Yes, warm air expands and rises, while cold air contracts and sinks. It could happen that a low cold air stream is forced to rise when coming up against a high mountain range. Though, once over the range, the cold air tends to cling to the far side of the range as it sinks into the bottom of the valleys on the other side.
When the air rises over the mountain which side of the mountain is dry and which side is warm?
The dry side of a mountain is called the leeward side. This is the side away from the wind. The dry area is known as a rain shadow.
Why does leeward side of a mountain not get much rainfall?
Because it is too high for the clouds to pass and the rain is released when it rises to the top of the mountain
Windward and leeward side of a mountain?
The windward side of a mountain is typically the west side of the mountain, receiving the various weather as weather moves west to east. The leeward side of a mountain opposes the windward side, making it the east side of the mountain, receiving little weather, blocking weather (rain) and warming air rapidly as it moves down this side of the mountain. The leeward side of mountains causes deserts, dry places, little rain, etc., for it releases warm air unto these places, and blocks weather (rain) from moistening them (I.E. Las Vegas, etc. on the eastern side of the mountain ranges).
What does the vegetation pattern on Oahu suggest about the wind direction?
air rises at it is pushed up a mountain slope by wind. As it rises it cools. When it reaches its dew point, condensation will occur and clouds will form causing precipitation. When the air passes over the ridge, it will begin to drop and warm and relative humidity will drop. The condensation on the windward side of the mountain will therefore be exposed to more rainfall and thus have more dense vegitation.
What happens to air as it rises over a mountain range?
On the windward side of a mountain range, air rises, cools, and drops its moisture. On the leeward side of a mountain range air descends, heats up, and dries the land. Deserts are common behind mountains. (493) Glencoe Texas Science, Grade 8 © 2002
How did mountains add desertification?
Due to the change in atmospheric conditions a mountain can cause, the windward side of the mountain received the rain while the leeward side of the mountain does not receive the moisture creating a desert landscape. As the moisture rises to overtake the mountain the clouds condense creating rain on the windward side which creates an atmosphere of little to no moisture on the leeward side of the mountain.
Large mass of rocks and soil slippin down a mountain side?
it is a landslide
How do convection currents form downdrafts in deserts near tall mountain ranges?

Why one side of a mountain usually has more precipitation than the other side?
There are a number of reasons, the most obvious is that all the rain may have fallen on the front portion of the mountain, leaving little or no moist air to reach the other side of the range. Clouds from in bands of cool air where the moisture can condense. It is also possible that an inversion level may exist, this means a large body of warm air sits on top of the cloud layer, and the layer becomes trapped agains the mountain and warm air (above it).
The effect of air losing moisture as it rises up a mountain slope resulting in significant precipitation on the windward side and very little precipitation on the leeward side is known as the?
THE LEEWARD SIDE IS HOTTER
What does avalanche?
a mass of snow, ice, and rocks falling rapidly down a mountain side
