Download Solution PDFThe correct answer is Option 3.
Key Points
- Block Mountain: The correct example is the Black Forest (a)(ii). Block mountains are formed due to the faulting and uplifting of Earth's crust, creating elevated blocks between valleys.
- Old Folded Mountain: The Appalachian Mountains (b)(iv) represent this category. These mountains are formed through folding but have been significantly eroded over time.
- Relict Mountain: The Scottish Highlands (c)(iii) are remnants of ancient mountains eroded over time, leaving behind isolated highlands.
- Young Folded Mountain: The Himalayas (d)(i) are still tectonically active and represent the classic example of young folded mountains formed due to the collision of tectonic plates.
Important Points
- The classification of mountains is based on their mode of formation. Mountains can broadly be categorized into block mountains, folded mountains, volcanic mountains, and residual/relict mountains.
- Folded mountains (both young and old) are formed due to the compressional forces that fold the Earth's crust.
- Residual or relict mountains are formed due to prolonged erosion, leaving behind resistant rock masses.
