The correct Answer is A-4, B-1, C-2, D-3
Explanation
This question requires matching various landforms with the geomorphic agents responsible for their formation. Geomorphic agents include running water, glaciers, waves and currents, and groundwater, each creating distinctive erosional and depositional features.
Statement-wise Analysis
- A. Stalactites - 4. Groundwater:
- Correct. Stalactites are depositional features found in limestone caves, formed by the precipitation of calcium carbonate from groundwater seeping through the cave roof.
- B. Point Bars - 1. Running Water:
- Correct. Point bars are depositional features found on the inside bend of a meandering river, formed by the deposition of sediment by running water where the current velocity is lower.
- C. Moraines - 2. Glacier:
- Correct. Moraines are accumulations of glacial till (unsorted debris) deposited by glaciers. They can be terminal, lateral, medial, or ground moraines, depending on their position relative to the glacier.
- D. Spits - 3. Waves and Currents:
- Correct. Spits are depositional landforms that are long, narrow ridges of sand or shingle projecting from the land into the sea, formed by the depositional action of longshore drift (waves and currents).
Key Takeaway
Landforms such as stalactites, point bars, moraines, and spits are distinctively associated with the geomorphic agents of groundwater, running water, glaciers, and waves and currents, respectively.
