Question

7/10
how do tectonic plates move according to the theory of plate tectonics?
expansion of the earth’s core
gravitational pull from the moon
convection currents in the mantle
magnetic forces from the sun

Explanation:

The theory of Plate Tectonics states that the rigid tectonic plates float on the semi-fluid asthenosphere (upper mantle). Heat from Earth's interior creates circular convection currents in the mantle; these currents drag the overlying tectonic plates, causing their movement. The other options are incorrect: Earth's core expansion is not a driver of plate motion, lunar gravity causes tides not plate movement, and solar magnetic forces have no significant role in plate tectonics.

Answer:

Convection currents in the mantle
