Question

9 the movement of the plates is caused by (4 points)
convention currents
pressure
speed
density

Explanation:

In the context of plate tectonics (a subfield of Geography within Natural Science), the movement of tectonic plates is caused by convection currents in the Earth's mantle. Convection currents transfer heat, creating forces that move the plates. Pressure, speed, and density do not primarily drive plate movement in this geological context.

Answer:

A. convention currents
