Quizplus · Accepted Answer

Erosion is the process of wearing away and removal of rock and soil materials by agents such as water, wind, and ice. This can cause a decrease in the elevation of a mountain over time. Lithification (choice A) is the process by which loose sediment is compacted and cemented together into solid rock. Sedimentation (choice B) refers to the deposition of sediment or particles that settle out of a fluid, but is not typically associated with the gradual decrease in the elevation of a mountain. Deposition (choice D) is the settling or laying down of sediment or other material by a natural agent, but is not typically associated with the gradual decrease in the elevation of a mountain.
