When air moves upward to areas of less pressure what often forms?
fog
What are areas of less dense warm air that can be forced upward?
Low pressure
What forms when air moves upward to areas of less air pressure?
This doesn't really make sense. Moving up will always be toward air of lower pressure. Rising air does tend to produce clouds and precipitation, though.
How do differences in atmosphere pressure create winds?
As dense, cool air moves into a low-pressure region , the less dense, warmer air is pushed upward. These pressure differences, which are the result of the unequal heating that causes convection, create winds.
What are the two factors that determine the movement of air mass?
Two main factors that influence air movement are pressure and temperature, though they are really the same thing. Air moves to places with less pressure, to "fill them up," and gets pushed away from areas with high pressure. Also, when air gets hot, it becomes less dense than the air around it and is pushed upward. When it gets cold, it becomes more dense, and sinks toward the ground.

What is the connection between temperature air pressure and wind?
A low pressure region should mean that the region is low in air. The air from the surrounding region (which is comparatively at higher pressure) moves into this low pressure region creating a wind. So, wind is the movement of air from a high pressure region into a low pressure region. Warm air is lighter than cold air. Warm air being lighter moves upward creating a low pressure region. So, wind could also be a movement of air from cooler to warmer region.
What causes the air pressure drop as you travel upward from earth's surface?
Pressure is the weight of air column on unit area. As you go upward, this air column gets shorter, its weight gets less, hence air pressure gets lower.
What happens to air pressure when you move upward away from sea level?
The farther up away you are from sea level the less air pressure there is.
Why does the cold air stay close to the ground?
It haves high air pressure.
Why does air expand as it moves upward through the atmosphere?
Air expands when it rises because of the pressure and temperature. While air rises, there is less compression and pressure on nearby air, so it expands, it's not as tight. Air also takes space. Think of it as units of stuff. People in mountains normally die because of the expanded air which is too thin to breathe, because all the molecules are apart and running away.
Why does the pressure drop as you travel upward from earth's surface?
Air pressure is caused by the weight of the atmosphere above an object. When one goes higher, there is less air above and so the pressure drops.
How is the atmospheric pressure associated witgh the land breeze?
Winds or breezes are caused by atmospheric pressure. When air is heated by the Sun, it warms and becomes less dense. This means that the parts of the air column making up the atmosphere vary between areas of warm air and areas of cold air. Areas of warm air are less dense and therefore have a low pressure as compared with areas of cold air which have a high pressure. To even out the pressure difference, the air flows from areas of high pressure to areas of low pressure and this flow of air is called the wind.
