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.
Beneath the tectonic plates is a thick layer of molten rock called magma. There is a lot of heat generated by radioactive decay deep in the Earth's core and this rises through the outermost magma layer causing it to flow. Since the tectonic plates are effectively floating on this magma layer they are affected by the flow and hence move.
The crust is broken up into plates and these plates move on top of the mantle.
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.

yes and no
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.
The heat transfer is moved to the crust. The earth's crust moves to the inner core
