When a liquid or gas is no longer heated, the heat source that drives convection currents is removed. As a result, the temperature differential that causes the fluid to circulate diminishes, and eventually the convection currents will slow down and stop as the fluid reaches thermal equilibrium.
Convection currents transfer heat from Earth's core to the mantle, causing the mantle material to flow and create movement in the lithosphere. This movement generates heat due to friction and pressure. So, convection currents help distribute heat within Earth's interior rather than produce it.
Wind and water. Air currents (wind) carry heat poleward. This is mainly heat transfer by convection. Water currents carry heat poleward. This is heat transfer by convection and conduction.
Circulating currents in a fluid are commonly referred to as convection currents. These currents arise due to the movement of the fluid caused by temperature differences, which lead to the transfer of heat within the fluid. Convection currents play a significant role in processes like ocean currents and the movement of air in the atmosphere.
Convection currents are responsible for the movement of heat (and mass) within a fluid system. Heat wants to go from where it is to where it isn't. When atoms and or molecules of a fluid (a gas or liquid, for example) are hotter then their companion particles, they are less dense and rise in the fluid. Cooler, more dense groups of atoms or molecules take their place. Convection currents are thus set up, and heat travels "around" the system via those currents. A link to the Wikipedia article on convection is provided.
If the heat source is removed, convection currents will eventually stop because there is no longer a temperature difference to drive the circulation of the fluid. As the fluid cools down to the surrounding temperature, the convection currents will gradually slow down and dissipate.
When heat is removed from a fluid, convection currents will slow down and eventually stop. This is because convection currents are driven by temperature differences within the fluid, and when the fluid reaches a uniform temperature, the driving force for convection diminishes.

If the heat from convection currents is removed, the movement of the fluid or air will slow down and eventually stop. This can disrupt processes like heat transfer and mixing in the fluid, leading to changes in temperature gradients and potentially affecting the overall stability of the system.
Nothing actually happens to convection currents when heat is no longer supplied. The currents are produced by applying heat, most often to the bottom. The warmed fluid is 'lighter' than the cold fluid surrounding so it rises to allow colder fluid to replace it and be heated. As soon as the heat is removed, all the fluid rapidly comes to a single temperature and convevtion does not happen! An opposite effect happens when cold air sits on the surface of a lake. In this case the water at the surface cools, gets 'heavier' and sinks. In this case the convection currents operates downwards.

The difference in temperature and density is the cause of convection currents in the earths mantle. Convection currents are the flow that transfers heat within a fluid.

When heat is removed from the fluid, the temperature of the fluid will decrease, causing the convection currents to slow down or even stop. This is because the temperature difference that drives the convection process will decrease, leading to a reduction in the movement of the fluid particles.
c. eventually stop. As the heat source is removed, the temperature gradient that drives convection currents diminishes, eventually leading to the cessation of the currents as the fluid reaches thermal equilibrium.
When the heat source is removed from a fluid, convection currents in the fluid will eventually slow down and dissipate as the fluid cools. The fluid will then return to a more quiescent state with less movement and mixing.
No. Convection currents are the circular motion of earth's wind. If the earth did not rotate, convection currents would not be. Does that make sense?
