Answer:
It's made of glacial debris, i.e, rocks and regolith.
Explanation:
Moraines are formed from this debris mentioned before that it's carried by a glacier. But its formation is not that simple, all you need to know is that a moraine is formed on a glacier, by its particules in self.
In formation processes, we could divided in two parts: passive and active.
- Passive processes: It's when is formed on the surface without a directly formation by ice movement, in this process can be formed hummocky moraines, this types of moraines has cross-stratification in its structure.
- Active processes: It's when a moraine is formed directly by the movement of ice, that process is called glaciotectonism.
