Correct option is B
The correct answer is (B) Fold Mountains
Explanation:
· Fold Mountains are formed when sedimentary rock layers deposited in geosynclines are compressed, folded, and uplifted due to tectonic movements.
· These mountains arise because of compressional forces generated by the movement of tectonic plates toward each other.
· Famous examples include:
✔ The Himalayas (India)
✔ The Alps (Europe)
✔ The Rockies (North America)
✔ The Andes (South America)
Information Booster (SSC Essentials):
· Fold mountains are formed mainly along convergent plate boundaries.
· Sedimentary rocks like sandstone, shale, limestone undergo folding.
· Classified into:
✔ Young Fold Mountains – Himalayas
✔ Old Fold Mountains – Aravallis, Appalachians
Additional Knowledge (Expanded Headings):
1. Residual Mountains — Incorrect
· Formed by erosion, not folding.
· Examples: Western Ghats, Aravallis (older remnants).
2. Fold Mountains — Correct
· Created by continental–continental or ocean–continental collision.
· Contain major river systems and biodiversity.
3. Block Mountains — Incorrect
· Caused by faulting (uplifted blocks).
· Examples: Vosges, Black Forest.
4. Volcanic Mountains — Incorrect
· Built by lava eruption.
· Examples: Mount Fuji, Kilimanjaro.
