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.

∙ 13y agoBeneath 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.

How does tension change the shape of earths crust?
by pulling it making it thinner in the middle
Earth's outermost layer is the?
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.
Describe the movement of the crust at a hotspot?
The crust moves in 1 direction at a hotspot due to the convection currents of the mantle
What is direct evidence in science?
Physical samples of rock extracted (taken) from deep within Earths crust.
Which rock group makes up least of 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.
What are plate movement?
the movement of earths plates or crust
What theory explains changes in the earths crust?
Contenintal Drift theory
Does an earthquake mean there is a movement in the earths crust?
yes and no
What is a geololgist?
a person who studies the movement of the earths crust
What causes stress earths crust?
The movement in earths plates create powerful forces that pull or squeeze the rock in the crust.
How is heat transfer in the earths mantle related to the movement of the earths crust?
The heat transfer is moved to the crust. The earth's crust moves to the inner core
Which movement of the Earths crust implies that the continental crust is less dense than the oceanic crust?
Plate tectonic movement and subduction zones.
Theory that explains changes in Earths crust by internal forces?
Plate tectonics
An earthquake is a shaking caused by the sudden movement of the earths crust?
True((;
What causes faults in Earths crust?
The constant plate movement
What theory explains the movement of the pieces of earths surface?
theory of plate tectonics
What is the name of the long deep valleys that are formed by the movement of the earths crust?
rifts
