The earth's crust moves because the earth has tectonic plates that move because the magma under the earth's surface is constantly boiling. Since the water moves, it causes the earth's crust to move.
by pulling it making it thinner in the middle
Earths outermost layer is the crust.Actually, the crust is divided into two parts,Sial and Sima.In that way, actually Sial is the outermost layer of the crust,as it lies above the Sima.
The crust moves in 1 direction at a hotspot due to the convection currents of the mantle
Physical samples of rock extracted (taken) from deep within Earths crust.
Just to say: This question refers to rock groups. Not what type of rock.Igneous rocks make up most of the earth's crust.

Contenintal Drift theory
a person who studies the movement of the earths crust
The movement in earths plates create powerful forces that pull or squeeze the rock in the crust.

Alfred Wegener named his theory of the horizontal movement of the Earth's crust "continental drift."
