Worked Solution & Example Answer:GLACIATION Which of the following are all features of glacial deposition? Esker, moraines, drumlins - Junior Cycle Geography - Question 9B - 2012
Step 1
Esker, moraines, drumlins.
Answer
This selection includes key features associated with glacial deposition. Eskers are long, winding ridges formed by sediment deposited by meltwater streams beneath glaciers. Moraines are accumulations of debris that have been pushed along by the glacier, while drumlins are smooth, elongated hills formed by the advance of glacier ice.
Step 2
Corries, drumlins, erratic.
Answer
This selection is incorrect. While drumlins are indeed a feature of glacial deposition, corries (or cirques) are primarily features of erosion rather than deposition. Erratics are boulders that have been transported by glacial action, but they do not represent major depositional landforms.
Step 3
U-shaped valleys, moraines, cirque (corrie).
Answer
This selection is also incorrect. U-shaped valleys are formed by glacial erosion rather than deposition. Moraines do signify deposition, but cirques, like corries, are areas where glaciers erode the landscape rather than deposit material.
