At the bottom of a substance, part of it is heated by something. This causes it to rise above the rest. However, it soon cools and drops back down again where it is then heated, etcetera. This forms a constant current of part of the substance rising then dropping and repeating.

Is convection current kinetic energy before transferring?
In a convection current the kinetic energy will most likely be a small part of the total as the rate of flow won't be very high. Most heat transfer in convection will be simply thermal energy transfer, ie from a warmer place to a cooler one.
What is unique about the materials convection takes place in?
it is cool
The transfer of thermal energy by particles moving from one place to another is?

Does convention occurs in solids?
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.
