The correct answer is Delta: A delta is a fan-shaped deposit of sediment that forms where a river meets a larger body of water, such as an ocean or lake. Deltas are not formed by glaciers, but rather by the deposition of sediment carried by rivers.

Here are the options and explanations:

Cirque: A cirque is a steep-walled, semicircular basin that is formed when a glacier erodes a mountainside.

Arête: An arête is a sharp, narrow ridge that is formed when two glaciers erode the sides of a mountain.

Moraine: A moraine is a ridge of sediment that is deposited by a glacier.

Delta: A delta is a fan-shaped deposit of sediment that forms where a river meets a larger body of water.

Therefore, the correct answer is Delta.
