Match List I with List-II and select the correct answer using the code given below the Lists: List I (Landform) List II (Agent) A. Loess 1. Wind deposited B. Tombolo 2. Glacial deposited C. Point bars 3. River deposited D. Moraines 4. Sea deposited
Explanation
The landforms listed are created by distinct geomorphic agents. Loess is a wind-deposited (aeolian) landform consisting of fine, mineral-rich silt and dust that blankets large areas, such as the Loess Plateau in China [2]. Tombolos are sea-deposited features formed when waves and longshore currents deposit sand or gravel that connects an island to the mainland or another island [4]. Point bars are fluvial (river) depositional landforms found on the inside curves of meandering rivers, where reduced stream velocity causes sediment to settle [5]. Moraines are glacial depositional landforms composed of unsorted debris (till) left behind by moving or melting glaciers. Matching these pairs (A-1, B-4, C-3, D-2) aligns with standard geomorphological classifications of depositional processes across aeolian, coastal, fluvial, and glacial environments.
