The mountain peaks shown below were initially formed millions of years ago through the processes of folding, faulting, and overthrusting. image courtesy of the u. s. nps over the past several million years, these peaks have been gradually worn down. if not for the process of carrying small bits of sediment away, the peaks above might be 1,000 meters taller. a. erosion b. chemical weathering c. deposition d. physical weathering

A. Erosion  

Explanation:

Erosion is the process in which soil and rock are worn away and transported by wind or water and transported to another location.

The image below shows how water has eroded a coastline.

B is wrong. Chemical weathering is the disintegration of rocks by reactions with water and the acids dissolved in it

C is wrong. Deposition is the process in which sediments carried by wind, water or ice are deposited at another location.

D is wrong. Physical weathering is the breakdown of rocks and soil by physical processes like the freezing of ice in the cracks of rocks.
