When cold air moves into an area, we have high atmospheric pressure; the cold air is denser than the warm air. Love, me :)
I'm not sure what a "heavy" atmosphere is but Venus' atmosphere is denser than Earth's and the atmospheric pressure at the surface is much greater than Earth's
In general, metamorphic rock will have a higher density, because it's put under pressure, and will decrease in size because of that.
Low
because it has layers
Because since theyre is lack of heat to excite the molecules and keep them appart, the molecules tend to be closer together and denser then hotter air. Imagine a lava lamp the denser part sinks(low pressure) while the less dense part rises.
When cold air moves into an area, the atmospheric pressure is high because cold air is denser than warm air. When a cold front moves through an area, the pressure always rises.

Because water is denser than air.
A denser fluid would exert stronger pressure on an object in the fluid than a less dense fluid would because of the pressure differences. A denser fluid would have a greater pressure difference, therefore greater buoyancy, and exerting stronger pressure on the object.

Since weight is the measure of an object's gravitational pull, the compressed air does not weigh more. The difference is in the density of the air. A tank filled with compressed air will weigh more than a tank that is filled with air at normal atmospheric pressure.
The kinetic-molecular theory explains that there is more pressure at lower altitudes because there are more obstacles for the gas molecules to run into and create more pressure. They collide with the walls of their container as well as other molecules. And at higher altitudes, there is more space for the gas molecules to travel and not bump into things therefore not as much pressure is created. Also, some extra info: the atmosphere is denser closer to the Earth's surface because the weight of atmospheric gases at any elevation compresses the gases below.
Granite.
It increases. In an unpressurized airplane, the pressure increases because the air is denser at lower altitudes. In a pressurized airplane, the pressure increases both because the pressure must be equalized before the doors can open and because the hull is not designed to withstand an outside pressure higher than the inside pressure.
Neither. A single number cannot be dense.
In general, metamorphic rock will have a higher density, because it's put under pressure, and will decrease in size because of that.
when air is heated air pressure decreases because the molecules
