The cycle of rising and falling in a lava lamp is an example of B) convection. Convection is the process by which heat causes the movement of fluids (liquids and gases), resulting in the transfer of heat through the fluid itself. In the case of a lava lamp, the heated wax becomes less dense and rises, while the cooler wax becomes denser and falls, creating the characteristic motion.
This is a lava lamp. When the light bulb heals the wax, the wax rises. When the wax cools, it falls. This cycle of rising/ falling in an example of; A) conduction B) convection C) radiation D) none of the above
