because the process requires the formation of currents which is only possible in fluids (i.e solids and liquids). It is not possible for currents to develop in solids for the simple reason that the molecules in a solid are not free to move around and they are contained in their fixed positions.
Material does not flow in solids; convection is heat transfer through flow of material.
Because the atoms in solids are fixed in place, they can not "convect".
The molecules in a solid cannot move, as is required for conduction.
Solids are rigid.
Convection implies movement of matter.
Convection of mass cannot take place in solids, since neither bulk current flows nor significant diffusion can take place in solids. Diffusion of heat can take place in solids, but is referred to separately in that case as heat convection.
by The movement of heated particles of a gas or a liquid. convection cannot take place in solids because solids have fixed shape. particles like Pizza
..to flow as easily. A malleable (space between particles) structure is need for convection to take place.
they have no energy
Sure there can be conduction, but quite often, most of the heat will be transposrted by convection, not conduction.

Wrong, transfer of heat does take place in fluids. In fact it can take place more efficiently in fluids than in solids because convection is possible in fluids.
Convection take place because of convection currents
they have no energy
Convection
convection takas place wen iron piece is heated
convection takes place in the outer core......... i think
