What is the primary driving force behind mass wasting processes?

• A. Water
• B. Temperature
• C. Gravity
• D. Soil composition

Answer: (C)

The primary driving force behind mass wasting processes is gravity. Mass wasting refers to the movement of soil and rock materials down slope due to the gravitational pull acting on them. Gravity causes materials to shift and slide, especially when they become unstable, leading to events such as landslides, rockfalls, and other forms of erosion. While water, temperature, and soil composition can influence the occurrence and rate of mass wasting by affecting material stability, they do not serve as the driving force in the same way gravity does. Water can increase the weight of materials or reduce friction, temperature can affect soil consistency, and soil composition can determine the strength and cohesiveness of the materials involved, but it is ultimately gravity that causes these masses to move.
