The correct option is A-3, B-4, C-2, D-1
Explanation
Major landforms such as mountains, plateaus, plains, and deserts are characterized by distinct geomorphic features formed by natural agents (wind, water, ice). Human settlement patterns also vary significantly across these landforms based on resource availability and terrain suitability.
Detailed Analysis:
- A. Glaciers (Matches 3. Mountains): Glaciers are slow-moving rivers of ice formed by the accumulation and compaction of snow. They are primarily found in high-altitude mountain regions (e.g., the Himalayas) and polar areas.
- B. Hundru Falls (Matches 4. Plateau Area): Hundru Falls is a significant waterfall located on the Subarnarekha River in the Ranchi district of Jharkhand. It is a characteristic feature of the Chota Nagpur Plateau, formed where the river drops from the plateau escarpment.
- C. Thick Population (Matches 2. Plains): Plains (e.g., the Indo-Gangetic Plain) offer flat terrain, fertile alluvial soil, and ease of transport. These conditions support intensive agriculture and urbanization, leading to high population density.
- D. Sand Dunes (Matches 1. Deserts): Sand dunes are depositional landforms created by wind action (aeolian processes). They are a defining feature of arid and semi-arid desert regions (e.g., the Thar Desert).
Key Takeaway:
Hundru Falls is associated with the Chota Nagpur Plateau (Subarnarekha River). Plains are the most densely populated landforms, while glaciers and sand dunes are specific to mountains and deserts, respectively.
