Warm air is above cool air.
By solar energy
"Cool air rises and warm air falls" is false. Cool air is denser than warm air, and therefore warm air will rise above cold air.
Cool air typically flows under warm air due to the principle of convection, where cooler, denser air sinks while warmer, lighter air rises. This creates a cycle of air circulation where cool air replaces warm air near the surface.
An occluded front is formed when a fast-moving cold front catches up to a slow-moving warm front and lifts the warm air mass off the ground. This creates a complex weather system with both cold and warm air masses aloft, while cool air is found below.
yes the cool denser air sink while the warm less dense rises
When warm air moving above mixes in with cool air moving below.
True. Surface currents can warm or cool the air above them, depending on the temperature of the current and the direction of the wind. Warm currents will typically warm the air above them, while cold currents will cool the air.
clouds form above chimneys as the warm air mixes with the cool air
By solar energy
A stationary front occurs when a warm air mass is trapped and unable to move, with cooler air both above and below it. This can lead to prolonged periods of cloudy and rainy weather.
"Cool air rises and warm air falls" is false. Cool air is denser than warm air, and therefore warm air will rise above cold air.
Because warm air is less dense then cool air.
Cool air layered over warm air is a more stable atmospheric condition because cool air is denser and does not rise easily through the warmer air above it. This creates a more stable environment where weather systems are less likely to develop or intensify. Warm air layered over cool air can result in more unstable conditions and lead to the formation of thunderstorms and other severe weather.
A warm air is less dense than cool air (Option A). When air is heated, the air molecules become more energetic and spread out, decreasing its density. Conversely, cool air has denser molecules as they move slower and are more tightly packed together.
Warm water warms and moistens the air directly above it. If this warm, moist air is uplifted it will cool and the moisture in it will condense, producing rain and potentially storms.
Cool air typically follows warm air. Warm air rises and creates an area of low pressure, which is then filled by cooler air moving in to replace it. This movement of air is known as convection.
Rain will fall.
