Question

dynamic earth mid - unit test - part 1
what makes plates move?
radiation from the sun
warm air currents on earths surface
conduction of heat between plates on the surface
heat convection within the earth

Explanation:

The movement of Earth's tectonic plates is driven by heat convection in the mantle. The mantle is semi - molten and the circulation of hot and cooler material creates forces that move the plates above. Radiation from the sun affects the Earth's surface climate but not plate movement. Warm air currents on the Earth's surface are part of the atmosphere and do not cause plate motion. Conduction of heat between surface plates is not the main driving force for plate movement.

Answer:

heat convection within the earth
