Convection typically occurs in fluids like water and air. It is a mode of heat transfer where heated particles in the fluid rise, while cooler particles sink, creating a circulation pattern that transfers heat throughout the material.
Conduction and convection require a medium, such as solids or fluids, to transfer heat through direct contact or movement. Radiation, on the other hand, can occur in a vacuum or through empty space as electromagnetic waves. So, for conduction and convection to take place but not radiation, a medium for heat transfer is necessary.
Convection requires the movement of a fluid medium to transfer heat. Since solids do not have the ability to flow like liquids or gases, convection of current cannot take place in solids when they are heated. Heat can still be transferred through conduction in solids, where it is transferred from one molecule to another through direct contact.
An example of conduction is when a metal spoon in a hot drink gets hot at the handle end. An example of convection is when warmer air rises, causing cooler air to move in and take its place, creating a convection current.

Convection takes place because cool air is less dense than warm air.

Convection takes place in the Earth's mantle, which is the layer of hot, semi-solid rock located between the crust and the outer core. Heat from the Earth's core drives convection currents in the mantle, causing the movement of tectonic plates.
