Question

Quizplus · Accepted Answer

The terminal moraine is the ridge or mound of glacial debris deposited at the farthest extent of a glacier. It marks the maximum advance of the glacier. Hanging valleys are formed when smaller tributary glaciers join the main glacier and then melt away, leaving a cliff or steep valley. Lateral moraines are debris deposits on the sides of a glacier. Valley trains are sediment deposits left by braided streams flowing from the glacier. Tarns are small mountain lakes formed in cirques or depressions left by glacial erosion.
