GPT-4o mini
When glaciers melt and recede, they leave behind **moraines**. Moraines are accumulations of dirt and rocks that have been scraped up and carried along by the glacier. When the glacier retreats, these materials are deposited, forming various types of moraines, including terminal, lateral, and ground moraines.
The other options have different meanings:
- **Dunes** are formed by wind and are not directly related to glaciers.
- **Icebergs** are chunks of ice that break off from glaciers and float in water, but they are not left behind once the glacier melts.
- **Loess** is a windblown silt that is not specifically related to glacial activities.
So, the correct answer is moraines.
