What types of moraines are shown as the dark stripes in the figure below?

Question

Quizplus · Accepted Answer

The dark stripes in the figure are located on the surface of a glacier and run approximately down the middle of the glacier. These are characteristic of medial moraines, which form when two glaciers merge and their individual lateral moraines become merged in the center of the combined glacier. Terminal moraines occur at the end of a glacier, lateral moraines are located along the sides of a glacier, and recessional moraines are formed during temporary halts in the retreat of a glacier. None of these types of moraines are depicted in the figure.
