It haves high air pressure.
Cold air molecules have less motion, and are therefore packed more closely together than warm air molecules. The denser, heavier colder air moves downward and pushed out of the way and upward the warmer, less dense air.

tornado Thermals, caused by hot ground heating the air close above it. Replaced by cold air sinking from above.
cold air flows much like water close to the ground. in a low area like a vally the cold air will accumulate and you get frost damage
air masses are important because the unequal heating of the earth causes movement of huge volumes of air. air masses formed over cold areas stay cold throughout and air masses formed over warm areas stay warm throughout
if there was no solar energy then there would be no winds because the sun heats the ground and all the air around it and it rises and it pushes cold air down to the ground and the hot air cools off and the cold air warms up and that process of heating creates winds.
It is called a "cold front. It is the leading edge of a cooler mass of air that is replacing a warmer mass of air at ground level.
Cold air falls and hot air rises. That simple. Think of hot air balloons.
Warm air close to the ground rises and becomes cooler.

Fog appears when cold air sinks to the ground.

a cloud that's comes close to the ground when they get older tell them the real thing when hot air and cold air mix you get a fog. you could tell them when hot air and cold air mix or a cloud that's is hitting the ground hope i helped!!!!!!!!!
Becasue the air gets cold!
air near the ground becomes warm and expands.warmer air is less dense than cold air and therefore the warm air near the ground rises. air near the ground becomes warm and expands.warmer air is less dense than cold air and therefore the warm air near the ground rises.
cold air because when the temperature drops hot air rises and cold air comes to ground level,cold water and hot water have the same density.
it is heated by the ground , and becomes less dense and rises i found that in my science book I'm in 6th grade
Snow insulates the ground. It keeps the ground below it frozen which keeps the air around it cold.
