The forces that move tectonic plates push deep rocks up to Earth's surface, and also push rocks at Earth's surface down to great depths. Tectonic plate motion may also lead to volcanic activity.
hope this helps!
Oh, yeah? Then why'd you post this, hmm?
Isostatic rebound occurs when a load is imposed on or removed from the lithosphere. The surface tends to rise or sink as the lithosphere rises or sinks in the asthenosphere. Loads may consist of large lakes, oceans (on continental shelves during eustatic sea level rise), ice, sediment, thrust sheets, and volcanoes.
Deposition is the geological process in which sediments, soil and rocks are added to a landform or land mass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.
