Wind creates the surface currents that move water from the equator towards the poles. Water at the poles cools downs. The density decreases and it sinks. Water below the surface moves to areas with less pressure as it is pushed from above. As surface water is blown away, water from below the surface pushes up in an upwelling to take its place. Then the cycle repeats itself.

What is a cycle in which air is warmed and warm air rises and air is cooled and cooled air sinks?
The process you are describing is known as convection. This cycle occurs when a fluid, in this case, air, is heated, causing it to expand and rise due to lower density. As the air rises, it cools, becomes denser, and eventually sinks back down to be reheated, thus continuing the convection cycle.
What are the steps of a normal convection cycle?
In a normal convection cycle, warm air rises due to being less dense, cools down as it reaches higher altitude, becomes denser and sinks back down, and then gets warmed up again by the heat source, completing the cycle. This continual movement of air creates a convection current.
What step of the convection cycle in earths atmoshpere?
The step of the convection cycle in Earth's atmosphere involves warm air rising due to being less dense than the surrounding cooler air. As the warm air rises, it cools and eventually sinks back down, creating a continuous cycle of air movement. This convection process helps distribute heat and moisture around the globe.
What step in the convection cycle in earths atmosphere?
In the convection cycle in Earth's atmosphere, warm air near the surface rises due to lower density, creating a low-pressure system. As the air rises and cools, it loses moisture through condensation, forming clouds and precipitation. Eventually, the now cooler and denser air descends back to the surface, creating a high-pressure system and completing the convection cycle.
What is the cycle of convection currents in Earth?
convection currents r a cycle of heat in the mantle. the energy is produced by the heat in the core. the heat rises it becomes cooler and has a greater density. when the desity starts to decrease, it gets hotter and goes round and round in the cycle for many years. but, when the heat is on the top and it rises, the mantle can open up and cause sea floor spreading to occur.
What are the differences of conduction and convection?
Convection has a cycle of what happens. Conduction dosent have a cycle
The cycle of heating rising cooling and sinking is called?
The convection / subduction cycle.

What is the continuous cycle of warming and cooling of the air called?
The Convection Cycle
What is the cycle of hot and cold gas?
convection
How are convection related to the water cycle?
The water cycle transfers heat in the form of liquid.
Which geochemical cycle involves mantle convection?
The geochemical cycle that involves mantle convection is the rock cycle. Mantle convection plays a key role in the movement of tectonic plates, which influences the formation and destruction of rocks through processes like subduction and volcanic eruptions.
What is the cycle of heating rising and cooling?
convection current
Which is a step of convection cycle in earth atmosphere?
Hot, less-dense air rises.That would be "convection" cycle, and one of the steps is hot (therefore lighter) air rising.
