Heat added low down in a body of fluid (gas or liquid) causes some of the fluid to warm up. Because it's warmer, it's also less dense and so starts to rise through the body of the fluid like a hot-air balloon, except without the skin.

hii dear here is ur answer _____________ ⤵️
● " so in metals where the charge carries ( electrone) are negative , conventional current are in opposite direction as the electrons. In a vacuum a beam of ions or electrons may be formed .

I HOPE ITS HELPFUL.

Convection currents form when you have a liquid or gas have regions with a difference in temperature and there is a heat source feeding the system. Colder areas are going to want to fall and hotter regions want to rise.
As the hotter regions raise they lose energy (heat) and begin to fall and the now warm regions rise. This happens in a circular pattern.
