Question

a process by which the earth's surface is changed through rock movements and displacement

Answer 1

Answer:

The process which changes the earth's surface through rock movements and displacement is known as an Earthquake.

Earthquakes are a result of some other phenomena occurring on the earth’s surface like volcanoes, landslides, etc., which cause the rocks below the Earth’s crust to shift and displace.

These phenomena cause undue stress on the rocks and tectonic plates in the Earth’s crust, forcing them to displace, thereby releasing some of the stress.  

Answer 2

Answer: Diastrophism

Explanation: Diastrophism changes the Earth's surface by rock movements and displacements. Diastrophism results in folding and faulting. Faults are large crustal features formed by the movement of the lithospheric plates of the Earth.

Types of faults are the normal, transform, reverse, and oblique-slip. Faults that are seen at the surface may form ridges along the fault line called fault scarps.
