Monarchs, such as royal families.
What are all the options?
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.
<h3>Why do plates move?</h3>
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.
