It is upward motion that produces clouds - lift air, and it expands (gravity's pull decreases with altitude) and cools (as do all gases when they expand). The moisture content remains the same, however, and once the air cools enough so that it is saturated by its moisture content, clouds will begin to form.

What are the tall puffy kinds of clouds that form by vertical motion in warm and relatively humid air?
You are in Geo 1301 aren't you. >.>
Do clouds form easily when the air pressure is high or low?
Clouds only form when the air pressure is low.
What is the upward movement of warm air and the downward movement of cold air?
Conduction
Why do clouds form more in the air than on earth's surface?
the white clouds
Do clouds fly?
No, they are suspended in the air and atmosphere by air currents.
What force opposes the downward motion of falling object?
Air resistance
How does the downward component of the motion of a projectile compare to the motion of free fall?
They are the same, if the effect of air resistance is ignored.
Can clouds ride the jet stream?
yes because the jet stream is wind and clouds are lighter than air and when air is in motion it is wind.
Is the pressure of the clouds being compressed and heated which cause the lightning?
No. It is the buildup of static electricity in the clouds, caused by the motion of the air within the clouds.
If stratus clouds are dark what are they called?
Because there can be a lot of water in warm air, stratus clouds can easily turn into dark, rain and snow-producing nimbostratus clouds.
Does wind speed affect cloud movement?
Winds at the same altitude as clouds can influence their direction. However, the motion of clouds within an air mass is determined with respect to the motion of the air mass over the Earth's surface. Winds can vary considerably with altitude.
If air resistance is neglected what is the motion of an object projected at an angle consists of a uniform downward acceleration combined with what?
a constant horizontal speed
Why do clouds form behind a moving cold front?
They form from behind the moving cold front because the warm air condenses quickly producing clouds, rain, and stormy weather.
What effects a parachute from falling faster?
* The downward facing area of the chute * The density of the air * The mass being lowered by the chute * The integrity of the chute * The motion of the air around the chute

What is full of or covered by dense clouds?
Cumulonimbus clouds are usually the type of moisture producing clouds. Bear in mind that the altitude of a cloud may vary the type of cloud; air temps can make the difference between rain or snow.
What is downward displacement of air?
Downward displacement of air happens when you fill the upper part of a pressure chamber with steam. This causes the denser air below to move downward.
