Match Column A (Denudational Processes) with column B ( Their Driving Forces/Energy):
Show answer & explanation
Correct answer: A
Explanation
Answer: A - 2, B - 3, C - 1, D – 4
Explanation: This question is based on geomorphology in Geography, specifically denudational processes, which wear down Earth’s surface.
Weathering → 2
Driven by chemical actions, molecular stresses, temperature changes
Occurs in situ (no movement of material)
Mass Movement → 3
Controlled by gravity
Includes landslides, soil creep, rockfall
Erosion & Transportation → 1
Requires kinetic energy (water, wind, ice movement)
Involves removal and movement of material
Denudation (overall process) → 4
Controlled by external forces acting on Earth’s surface
Includes weathering, erosion, transport, deposition
Additional Key Facts
Denudation = wearing down + lowering of Earth’s surface
Major agents: Running water, Wind, Glaciers and Gravity
It is a key concept in landform evolution
