A convection current, however, this can also occur with gases.
a convection current transfers heat within a fluid.
The transfer of heat by fluid is convection.
The convection of the water cycle is evaporation, condensation,precipitation,runoff

"Convention"? I think you mean "convection" currents, and they will die away quite rapidly as the fluid and its container cool.
convection
Convection refers to the transfer of heat energy by the motion of a fluid such as air or water caused by differences in temperature within the fluid. Therefore convection happens wherever there is a fluid with a temperature gradient. This means that convection is happening continuously in the air around us and in bodies of water. A car heater and a convection oven are also considered to transfer heat by convection, but this is using the term liberally since the movement of the fluid (air) in these two cases is caused by a fan, not temperature gradient. So, while not perhaps being absolutely accurate examples of convection, still the heat is transferred through fluid motion.

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.

It is called Convection.
Convection currents happen in a fluid that is on top of a hot base.1. Cold fluid is heated up at the bottom2. The now hot fluid rises up and is replaced by other cold fluid3. When the hot fluid gets to the top, it flows to a side (pushed by hotter fluid rising)4. It cools down and flows to the bottom again5. REPETITION
