question 21 of 25
what causes earths tectonic plates to move?
a. convection currents
b. gravitational changes
c. crust destruction
d. atmospheric pressure

Explanation:

Convection currents in the Earth's mantle drive the movement of tectonic plates. Heat from the Earth's interior causes the mantle material to rise, spread out, and then sink back down, creating a circular - like motion that moves the plates above. Gravitational changes, crust destruction, and atmospheric pressure do not directly cause the movement of tectonic plates.

Answer:

A. Convection currents
