Question

in which form of heat transfer do changes in temperature and density play a role in moving tectonic plates? continental conduction convection radiation

Explanation:

To determine the correct answer, we analyze each option:

• "Continental" refers to continental drift or continental plates, not a heat transfer method.
• "Conduction" is heat transfer through direct contact, not involving density changes for tectonic plate movement.
• "Convection" involves heat transfer by the movement of fluids (like magma in the mantle). As magma is heated, it becomes less dense and rises; as it cools, it becomes denser and sinks. This convection current drives tectonic plate movement.
• "Radiation" is heat transfer via electromagnetic waves, not related to density - driven movement of tectonic plates.

Answer:

C. convection
