Convection occurs when and where a fluid is in a gravity field and heat is applied to its base.
Convection currents are in the liquid and gas states.

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.
Natural convection and turbulence are most likely to occur when there are significant differences in temperature or density within a fluid. This can lead to the formation of convection cells and vortices, which contribute to turbulence. Factors such as heating, cooling, and mixing can also enhance natural convection and induce turbulence in a fluid.
A convection current, however, this can also occur with gases.

Convection occurs mainly in the gaseous state, where heat is transferred through currents in air. Convection can also occur in liquids, however it is generally identified with gases.gas and liquid
Convection is most likely to occur in fluids, such as liquids or gases, due to the movement of their particles. Additionally, convection can also occur in certain solids that are capable of flowing, such as molten lava or heated metals.
They occur when the convection currents are less dense and rise.
When smoke goes up through a tube to a container and into fire.
Convection currents occur in the mantle, which is the middle layer of the Earth. The heat generated from the core causes the molten rock in the mantle to move in a circular pattern, creating convection currents.

Convection occurs in any liquid or gas that has variations in density due to uneven heating.
