The correct answer is B) After the stove is turned off convection currents continue to transfer energy to the water for a period of time.
The statement that best describes the convection currents is: After the stove is turned off convection currents continue to transfer energy to the water for a period of time.
Convection currents transfer heat. By mass motion of a fluid, it could be water, convection currents transfer the heat from one place to another. Besides water, it could be air or molten rock. The transfer of heat of convection currents is what makes ocean currents possible, and weather. So conduction currents depend on the motion of the water and the motion of the air.
The other options of the question were, a) convection currents move thermal energy from the stove to the pot, c) connection currents in the water cause warmer, denser water to rise and transfer energy upward, and d) when the stove is turned on conviction currents cause an increase in the chemical energy of water molecules.
