GK QUESTION#3042
Match the denudational processes with their driving force or energy in the NCERT geomorphic-process classification.
Read each row across both columns.
| Column A (Denudational processes) | Column B (Driving force or energy) |
|---|---|
| A. Weathering | 1. Kinetic energy |
| B. Mass movement | 2. Gravitational or molecular stresses and/or chemical actions |
| C. Erosion and transportation | 3. Gravitational force |
| D. Denudation (overall process) | 4. External forces acting on Earth’s surface |
Show Answer
Answer
A. A-2, B-3, C-1, D-4
Show Explanation
Explanation
The matching is A–2, B–3, C–1, D–4. In the NCERT geomorphic-process classification, weathering involves gravitational or molecular stresses and chemical actions; mass movement is driven directly by gravity; erosion and transport involve kinetic energy. Denudation is the broad group of exogenic surface processes. These are Geography classifications, not separate exclusive fundamental forces.
