Question

Which of the following is a subsurface event that takes place during the rock cycle?

Deposition

Erosion

Weathering

Plate tectonics

Answer 1

Strictly speaking, they all can happen in the subsurface, depending on what you define as the surface. However, cementation and melting are pretty well confined to the subsurface, whereas erosion and weathering are primarily surface processes. I would mention karst as a type of environment where erosion and weathering occur in the subsurface, as an example.
