What information do geomorphologists infer from a drumlin swarm?
Answer and explanation
Correct answer: Indication of former ice-flow direction and ice movement
A drumlin swarm is a group of streamlined hills shaped beneath former moving ice. Their long axes, and commonly their tapered ends, are aligned with the direction of ice movement. Mapping many drumlins therefore helps reconstruct the former glacier’s flow path and ice dynamics. Tides, karst-water hardness, and estuary salinity are not identified from drumlin alignment.
