Question

Quizplus · Accepted Answer

Cirques, horns, and arêtes are landforms that result from the erosion or removal of rock and sediment by glaciers, which is a form of glacial erosion. On the other hand, moraines, erratics, and till are formed from the deposition or accumulation of rock and sediment by glaciers, which is a form of glacial deposition. Therefore, the correct option is A, erosion; deposition. Options C and D are incorrect because they refer to the movement of glaciers, which is not directly related to the formation of these landforms. Option B is also incorrect because it presents "carving" as the cause of deposition, which is not a suitable term to describe the process.
