a. The energy is transferred to the gravel through a process called conduction. Conduction is the process by which heat energy is transmitted through collisions between neighboring atoms or molecules. In this case, the heater generates heat, which is transferred to the gravel that is in direct contact with it. The atoms in the gravel vibrate more rapidly as they absorb the heat energy, and these vibrations spread to the neighboring atoms, thereby heating the entire gravel bed.

b. The energy is transferred throughout the water in the aquarium through a process called convection. Convection is the movement of heat because of the bulk movement of molecules within fluids (gases and liquids). When the gravel gets heated, it heats the layer of water that is in direct contact with it. This heated water expands, becomes less dense, and rises to the top. The cooler, denser water from the top then sinks to the bottom where it is heated by the gravel. This cycle continues, creating a convection current that distributes the heat throughout the entire aquarium.
