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.
Once the pot is no longer heated, the temperature of the liquid inside will begin to stabilize and the convection currents will gradually slow down and eventually stop as the temperature equalizes throughout the liquid.
Convection currents are in the liquid and gas states.
A hot drink is warmed by convection currents, where the hot liquid rises and displaces cooler liquid, creating a circulation pattern that helps distribute heat evenly throughout the drink.
Heat reaches the thermometer in the heated beaker primarily through conduction and convection. As the beaker is heated, the water molecules gain energy and transfer that energy to the thermometer through direct contact. Additionally, as the warmer water rises and cooler water descends, convection currents help distribute heat throughout the liquid, ensuring that the thermometer accurately reflects the water's temperature. This process allows the thermometer to register the temperature of the liquid efficiently.
Convection currents in the mantle are streams of fluid produced by the process of heat transfer from one place to another. The earth gets very hot as you go nearer to the core. The mantle is thus heated up as it is right next to the core. As a result, convection currents are formed.*Core: It is a spherical zone that lies at the center of the earth.*Mantle: It is the layer surrounding the outer core of the earth.
Convection currents from the stove or microwave.

It falls back down
because convection currents are caused by the liquid being heated, becoming less dense due to increased kinetic energy and rising. if you are heating the top of the test tube, there is nowhere for them to 'rise' to, so no current is formed, as they do not reach a place where they cool and sink to the bottom. thus convection currents are only formed when heating the bottom of a test tube.
It'll stop flowing when all of the material has reached th same temperature.
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.

Convection currents.
Convection currents are the flow of fluid (liquid or gas) caused by the molecular motion resulting from the transfer of heat through the fluid. In meteorology it is the vertical movement of atmospheric gases caused by heat, atmospheric pressure, condensation of water vapor, and other factors.
If Earth's interior cools to a non liquid state, the convection currents will stop.
Convection- heat transfer in a gas or liquid by the circulation of currents from one region to another.
Convection currents occur in any fluid in which there is a temperature differance. Most convection currents occur in the mantle, the layer of semi-liquid rock below the crust. These currents are the reason behind plate tectonics.
