Your question: What happens to warm moist air as it rises over the mountain dry air as it moves down the mountain?

What happens to warm moist air as it moves up a mountain Why think about change in density temperature and rainfall?

As warm, moist air rises up the side of the mountain – known as the windward side – it expands (because there’s less pressure) and it therefore cools. … It’s also why the windward side is rainy and the leeward side is dry.

What happens to the warm air as it rises?

When a warm air mass meets a cold air mass, the warm air rises since it is lighter. … On the other hand, when a cold air mass catches up with a warm air mass, the cold air slides under the warm air and pushes it upward. As it rises, the warm air cools rapidly.

What eventually happens to moist air if it rises high enough?

As it rises, its pressure and temperature drop causing water vapor to condense. Eventually, enough moisture will condense out of the air to form a cloud. … The air cools as it rises, and eventually clouds form.

What happens to air when it is compressed or allowed to expand?

What happens to air temperature when work is done on the air to compress it? When air is allowed to expand it cools, when is compresses it warms. … the decrease of air temperature with altitude, or of water temperature with depth.

What happens to dry air as it moves down the mountain?

The orographic effect creates cooler air moving up the windward side of mountains and warmer air moving down the leeward side. Often, as the leeward air plunges down the slope, it warms quite dramatically and rapidly. Such rapid warming and drying of air can produce very high winds known as Chinook or Foehn winds.

What factor most directly affects the movement of air?

The movement of air through Earth’s — or any planet’s — atmosphere is called wind, and the main cause of Earth’s winds is uneven heating by the sun. This uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

Is most responsible for the uneven heating?

Answer Expert Verified. The answer would be convection currents. Convection happens when atoms with a lot of heat energy in a liquid or gas transfer and get the room of particles with fewer heat energy.

Is air always moving?

Air is constantly moving around the earth. This moving air is called wind. Winds are created when there are differences in air pressure from one area to another. … This is what makes air move, creating the wind.
