Which type of moraine is formed along the sides of a glacier due to the accumulation of rock debris derived from valley walls through weathering and mass wasting?

A. Terminal moraine
B. Lateral moraine✓ Correct Answer
C. Medial moraine
D. Recessional moraine

💡 Solution & Explanation

Lateral moraines are formed along the margins of a valley glacier through the accumulation of rock debris that falls from adjacent valley walls due to weathering and gravitational mass wasting. Terminal moraines mark the farthest advance of a glacier, whereas medial moraines form where two lateral moraines merge within a trunk glacier.
