Answer 1

The cycle of rising and falling of the wax in a lava lamp is an example of **convection**. Convection is the process by which heat is transferred through the movement of fluids (liquids or gases). In this case, the heated wax becomes less dense and rises, while the cooler wax becomes denser and falls.
