Currents that form in heated air are similar to currents that form in warm water because heated air goes up and cold air goes down creating convection currents.
The convection current can't form if heated at the top because then, the hot air would just keep getting hotter; no air moves around.
similarity is currents form gyres. difference is currents are any movement of water in one specific direction and gyres are circular patterns of water
deep ocean currents form by the differences in the density of ocean water
Convection currents occur in the asthenosphere.
The sun causes currents in the ocean because it is warming the water in the ocean in the day while it is hot, and then in the night when the sun goes down, the ocean starts to cool. Since the air above the water is warmer than in the water, this causes the water to rise up to the warmth until it gets cooled by the night, or from rain. This is what created movement and currents in the ocean from the sun.

They start to form when different leveled currents create pressure and the water quickly jutts so create a type of friction which is heat.

With water or oceanic currents, the currents which move close to the surface of the sea are called surface currents. In such currents, wind acts on the water and the water piles up to form strong movement forces.
The Antarctic Bottom Water, North Atlantic Deep Water, and Antarctic Intermediate Water are three density currents that form in polar regions.
deep ocean currents form by the differences in the density of ocean water
This would demonstrate the convection currents that form as the water heats. The water near the bottom of the container will heat up because it is closer to the burner. Warmer water is less dense, so it rises to the top of the container, and the cooler, more dense water sinks to the bottom to be heated. As the water moves in the currents, the confetti will also move up and down, showing exactly how the water is moving.
Convection currents can form any time at any place, even in your stove or house. It is created when a warm fluid rises and moves, becomes cold, falls, and is heated up again. it is a cycle see!! For example, pretend you are boiling water. The fire heats up the water at the bottom, the water rises than cools when it is on the fire and is not being heated. So the cold water falls again and later heats up due to the fire. Oh yeah, warm fluid has less density, so it rises, cold fluids have a greater density, so it falls.
steam, which is a water form of a gas
Currents that originate near the equator are going to be warm water currents, and currents that form near the poles will be cold water currents. It is the temperature of the waters in these currents that influence the climates of the land masses by or around which they flow.
