This is a lava lamp. When the light bulb heats the wax, the wax rises. When the wax cools, it falls. This cycle of rising/falling is an example of:

• Conduction.
• Convection.
• Radiation.

Warm air rises and the cool air sinks demonstrates this type of heat transfer. 

• conduction
• convection
• radiation
• Insolation
