What are the forces that push and pull on the earth's crust causing its deformation?

Answer 1

I believe it is pressure building inside that is pushing it outwards Plate tectonics is the movement of the earth's crust over the Mantle. Very similar to the way the thin chocolate coating of a choc ice slides over the melting ice cream. Sometimes the plates collide and one dives under the other. This is called plate subduction. Sometimes they move in opposite directions and new sea floor wells up from below to seal the gap. This is called sea floor spreading. If the plates moves sideways against each other the sudden movement causes earthquakes as the two forces suddenly equalise.

Answer 2

The primary forces that push and pull on Earth's crust and cause its deformation are tectonic forces. These include compressional forces (pushing together), tensional forces (pulling apart), and shear forces (side-by-side movement). These forces result from the movement of tectonic plates at plate boundaries.

Answer 3

Stress.

There are internal stresses caused by the shifting of the tectonic plates and the stress of gravitational forces of the sun and moon.

Answer 4

plate tectonics?
