transfer heat by fluid motion
..to flow as easily. A malleable (space between particles) structure is need for convection to take place.
Because convection occurs by convection currents. Convection currents occur as a result of the movement of a body. Since solids cant move, convection only occurs in fluid, i.e., liquids and gases
The molecules in solids are not free to move around as they are in liquids and gasses. It's the movement of the molecules that creates the convection currents.
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.
conduction takes place in solids while convection takes place in liquids and gas.
Conduction occurs in solids and liquids but not gases. Convection occurs in gases and liquids.

Matter doesn't move easily in solids.

Conduction is the transfer of heat by direct contact. It is more likely to occur in soilds and liquids because the particles are closer and move slower.
Solids do conduct heat better than gases, although not necessarily better than liquids. Some solids are actually composite materials, because they can have a porous structure which contains gas within the solid, and this results in solids that do not conduct heat very well. But it is the gas component which has this insulating property.
