Cold air does not rise, your question makes no sense.
Yes. Hot air is less dense, and therefore lighter than cold air, so it will rise as cold air will drop. A perfect example of this, is smoking rising to the ceiling in a fire, or smoke rising out of your chimney.
examples are air rotating when heat and cold air move aroundthe sun to the ocean
The process of warm air rising and cold air sinking is called convection. This movement of air helps redistribute heat energy around the Earth, leading to atmospheric circulation patterns that influence weather and climate.
The term is "convection." Convection is the process where hot air rises due to its lower density compared to cold air, allowing it to carry heat upward.
Heat
A heat pump is designed to extract heat from the outside air, even during cold weather. It uses this extracted heat to warm the indoor air. This is why a heat pump blows warm air instead of cold air during operation.
A cold front brings in cold air. The cold air causes warm air to rise quickly. The rising air forms cumulus clouds. There is often heavy precipitation at a cold front.
the land gets heated up due to summer heat because of which hot air rises and mixes with the cold air ans condensation takes place and rain falls
Convectional currents look like a cycle. For example, if you have a radiator in a room, it will heat the air around it. That hot air will rise up and then cold air will replace it. This goes round and round in a cycle. This cycle of warm air rising and cool air falling is called convectional current. This current happens in only liquid and gas.
ruud furnace only blows cold air, no heat
An air conditioner blows out heat
Warm air naturally goes up/rises and cold air has to make a current where it can go until it reaches a warm current which is under the warm air.
