When a warm fluid rises and a cool fluid sinks.

Huh?
Convection Precipitation.
Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
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.
No. Convection occurs when warm air rises and cool air sinks. It is not limited to air, either, but can occur in virtually any liquid or gas.
Convection only occurs in fluids. Fluids are gases or liquids.

It refers to a region in which convection occurs.
When convection occurs in the air, winds are formed.

Conduction occurs in solids and liquids but not gases. Convection occurs in gases and liquids.
Convection only occurs in fluids. Fluids are gases or liquids.
Heat transferred in convection occurs through movements of fluids.
