The theory of plate tectonics implies that Earth's crust is composed of many lithospheric
plates that are in gradual, but continuous movement. Which statement explains the
movement of these lithospheric plates?
A
The underlying mantle layer is molten where convection currents cause the
movement of the lithospheric plates.
B
Earth's magnetic polarity differences at the poles cause the movement of the
lithospheric plates.
The gravitational pull from both the Sun and the Moon cause the movement of
the lithospheric plates.
C
Earth's rotation on its axis and its revolution around the Sun cause the movement
of the lithospheric plates.

The reason why the lithospheric plates that compose the Earth's crust are constantly moving is A. The underlying mantle layer is molten where convection currents cause the movement of the lithospheric plates.

Why do plates move?

The earth's crust is made up of lithospheric plates that rest on the mantle which is molten as a result of the high temperatures of the core.

Convection currents in the mantle result in the plates moving as the currents come up from the core to heat up the mantle.

In conclusion, option A is correct.

Tectonics are that Earth's crust is composed of many lithospheric plates are  in  continuous movement the convection currents in the mantle result in the plates moving as the currents come up from the core to heat up the mantle.

What is tectonic plates and its movement?

Tectonic plates also called lithospheric plates  are large, irregular solid rocks consist both continents and oceans.

The underlying mantle layer is molten, where convection currents cause the movement of the lithospheric plates. In other, words, The heat from the mantle make the tectonic plates move.

Therefore, it can be said that option A causes the movement of tectonic plates.
