Transcript text: 6. Which of the following is an example of a destructive force?
- A) Glacier formation
- B) Sediment deposition
- C) River erosion
- D) Mountain building
Solution
The answer is C) River erosion.
Explanation for each option:
A) Glacier formation: This is a constructive force. Glaciers can carve out landscapes, but the formation itself is a process of accumulation and growth, not destruction.
B) Sediment deposition: This is a constructive force. It involves the accumulation of sediments, which can build up landforms like deltas and beaches.
C) River erosion: This is a destructive force. It involves the wearing away of the riverbanks and the landscape through which the river flows, breaking down rocks and soil.
D) Mountain building: This is a constructive force. It involves the creation of mountains through tectonic activity, such as the collision of tectonic plates.
In summary, river erosion is an example of a destructive force because it involves the breakdown and removal of earth materials.
