Tectonic plates move due to ____
A
the moon
B
tsunamis
C
heated currents deep within Earth
D
the formation of mountains over time
Explanation: 

Detailed explanation-1: -Convection currents drive the movement of Earth’s rigid tectonic plates in the planet’s fluid molten mantle. In places where convection currents rise up towards the crust’s surface, tectonic plates move away from each other in a process known as seafloor spreading (Fig.

Detailed explanation-2: -In 1993 it was suggested that inhomogeneities in D” layer have some impact on mantle convection. Mantle convection causes tectonic plates to move around the Earth’s surface.

Detailed explanation-3: -These plates move due to convection currents in the mantle . Heat from the core makes magma in the mantle rise towards the crust. As the hot current nears the crust, it begins to cool and sink back towards the core. As the magma sinks, it drags the plates across the surface of the Earth.

Detailed explanation-4: -The Lithosphere: The Earth’s surface is made of tectonic plates. These plates are moved around by the convection currents within the mantle.
