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.
NO
Sliding friction occurs when two solids rub against each other.

conduction takes place in solids while convection takes place in liquids and gas.
yes, this is mostly true.
