Final answer:
When a glacier recedes, it leaves behind deposited material known as moraine, which is a mixture of rock, gravel, sand, and clay. Different types of moraines, such as lateral, medial, and terminal moraines, can form depending on the location and movement of the glacier.
Step-by-step explanation:
When a glacier recedes, it leaves behind deposited material known as moraine. Moraine is a mixture of rock, gravel, sand, and clay that the glacier picked up as it moved and carried with it. As the glacier melts, the sediment is deposited and forms various types of moraines, such as lateral moraines, medial moraines, and terminal moraines
.
For example, lateral moraines are ridges of sediment that form along the sides of a glacier, while medial moraines run down the center of a glacier where two glaciers merge. Terminal moraines are created at the end of a glacier and mark its farthest extent.
