In the context of geomorphological landforms, match the depositional features with their corresponding depositional agents: 1. Eskers - Glacial meltwater streams 2. Barchans - Aeolian wind action 3. Stalactites - Underground karst groundwater 4. Drumlins - Marine wave action Which of the pairs given above are correctly matched?

💡 Solution & Explanation

Eskers are winding ridges of stratified sand and gravel deposited by glacial meltwater streams flowing within or beneath ice sheets. Barchans are crescent-shaped sand dunes formed by unidirectional wind action in arid regions. Stalactites are calcium carbonate mineral deposits hanging from cave ceilings formed by dripping groundwater in limestone karst terrains. Drumlins are streamlined hills composed of unsorted glacial till shaped beneath moving ice sheets, not marine wave action. Coastal depositional features include spits, bars, and tombolos.
