Convection only occurs in fluids. Fluids are gases or liquids.
A convection current, however, this can also occur with gases.
It can occur through conduction, convection and radiation.

No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
A convection current, however, this can also occur with gases.
Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
Radiation is the only type of heat transfer that can occur through vacuum (space with no particles).

Convection
Convection currents take place in the mantle.
Convection currents are in the liquid and gas states.
