Which best describes the shape of a convection current?

linear
spiral
circular
wave

Answer;

The shape of convection current is circular

Explanation;Convection is type of heat transfer which involves the transfer of thermal energy in fluids, that is gases and liquids. Convection creates convection currents which helps in the distribution of thermal energy in all parts of a fluid. The convection currents occurs in a circular motion, such that heat is transferred from the hotter parts of a fluid to the cold parts of a fluid, until all the fluid attains the same temperature.The convection currents that aid in the transfer of thermal energy in fluids are created by the temperature differences together with density differences in fluids.
