Q: Which of the following is an endogenic force?

Answer: C. Volcanism — Endogenic forces originate within the Earth. Volcanism is an internal process that builds and modifies landforms.

Q: Weathering means:

Answer: B. Breaking down of rocks in situ — Weathering is the disintegration and decomposition of rocks at or near the Earth's surface without movement of the material.

Q: The removal of eroded material by moving water is called:

Answer: B. Transportation — Transportation is the movement of sediments from one place to another by agents like rivers, wind, or glaciers.

Q: A river in its youthful stage is most likely to form which feature?

Answer: C. Waterfall — In the youthful stage, vertical erosion is dominant, often creating waterfalls and gorges in steep terrain.

A. The movement of weather systems
B. Breaking down of rocks in situ ✓
C. Transport of sediments by rivers
D. Deposition of alluvial soil

Answer: B. Breaking down of rocks in situ

The removal of eroded material by moving water is called:

A. Weathering
B. Transportation ✓
C. Deposition
D. Mass wasting

Answer: B. Transportation
Transportation is the movement of sediments from one place to another by agents like rivers, wind, or glaciers.

A river in its youthful stage is most likely to form which feature?

A. Ox-bow lake
B. Flood plain
C. Waterfall ✓
D. Delta

Answer: C. Waterfall
In the youthful stage, vertical erosion is dominant, often creating waterfalls and gorges in steep terrain.

Which option is the best reason why deposition dominates in the lower course of a river?

A. The river gradient becomes steeper, increasing velocity
B. The load increases and the river gains more erosive power
C. The river loses velocity and can no longer carry all its load ✓
D. Weathering stops completely in the lower course

Answer: C. The river loses velocity and can no longer carry all its load
As the river approaches its mouth, the gradient decreases and velocity drops, so the river deposits much of its load.
