Step 1: Understanding the question.
The question asks for the landforms created by glacial erosion. Glaciers can erode the landscape to create a variety of features.
Step 2: Analyzing the options.
(A) Fjords: Correct — Fjords are steep, glacially-carved valleys filled with water, typically seen in coastal regions.
(B) Moraines: Incorrect — Moraines are formed by the deposition of debris, not by glacial erosion.
(C) Drumlins: Incorrect — Drumlins are formed by glacial deposition, not erosion.
(D) Cirques: Correct — Cirques are bowl-shaped depressions formed by glacial erosion at the head of a glacier.
Step 3: Conclusion.
The correct answer is (A), (D), as these landforms are formed through glacial erosion. Moraines and drumlins are formed through deposition, not erosion.
