How do motions affect Earth's crust?
Plate motions produce stress in Earths crust that leads to faults, mountain building, and earthquakes.
Do compression and tension affect the thickness of earth's crust?
Compression and tension can indeed affect the thickness of the Earth's crust. Compression can thicken the crust by folding and faulting, while tension can cause stretching and thinning of the crust through processes like rifting and faulting. These tectonic forces play a significant role in shaping the Earth's crust over geological time scales.
