Mo8-L6b: What are the Process That Transfer Thermal Energy?
Convection
Key Concept
Convection is the transfer of thermal energy by the What are the Processes that Transfer Thermal
movement of particles from one part of a material to Energy?
another. What are the three processes that transfer thermal
energy?
Convection only occurs in f uids.
This cycle of cooler water sinking and forcing warm-
er water upward is an example of convection.
The movement of f uids in a cycle because of
convection is a convection current.
Convection currents circulate the water in Earth’s
oceans and other bodies of water.
