What form does the crust do?

plate tectonics.


How can you define plate tectonics not plate tectonics theory?

But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theory aren't really two separate things. However plates are pieces of the Earth's crust which are moving.


Which theory describes the motion of earth's crust on its mantle?

plate tectonics=D


WHAT forces change earth's crust?

plate tectonics


What does plate tectonics cause a change in?

The earth's crust


What is the primary reason why the oceanic crust subducts below the continental crust and not vice versa when they collide together?

The oceanic crust subducts beneath the continental crust due to its higher density. Oceanic crust is basaltic and has a specific gravity of 3.3. Continental crust is granitic and has an average specific gravity of 2.9.


What layer of Earth makes up plate tectonics?

The crust


What is the bending and tilting of Earth's crust called?

Plate Tectonics .


What movements of the earth's crust and mantle are referred to as?

Plate tectonics.


Why is oceanic crust always subducted underneath the continental crust?

Oceanic crust is denser and thinner than continental crust, making it more likely to be subducted beneath the less dense continental crust. This process occurs because the denser oceanic crust is pulled downward into the mantle at convergent plate boundaries due to gravitational forces. The subduction of oceanic crust beneath continental crust helps to recycle Earth's materials and plays a key role in plate tectonics and the geologic cycle.


Does plate tectonics occur on venus?

No. Plate tectonics are not possible on Venus because the crust is too thick and the upper mantle is not softened by water.


What is the name of the process of denser crust sinking beneath less dense crust after collision?

The process is called subduction. It occurs when one tectonic plate is forced beneath another due to differences in density, typically in convergent plate boundaries. This subduction process is a key driver of plate tectonics.
