Once the inside is more liquid-like, the upper substance comes down because it's relatively colder, and the warmer substance moves up. that cycle keeps going.

To correctly roast a marshmallow, take the marshmallow and leave it on the left side of the fire until that side is perfectly roasted (by letting it heat and change color twice), then quickly move your mouse to the middle under the campfire doing the same thing and finally move your mouse to the right of the campfire and completely roast the marshmallow. Put the marshmallow on the empty plate and start again!
Convection takes place because cool air is less dense than warm air.

Materials that allow convection to take place are usually fluids or gases, as they can easily move and transfer heat through the process of convection. Solids can also participate in convection to a lesser extent, especially if they have some degree of flexibility or ability to transmit heat through them. In general, materials that can move or flow are more likely to enable convection.
