Consider the following statements about glacial landforms: Statement 1: Hanging valleys are often found opening into main glacial valleys at higher elevations. Statement 2: Spurs of such hanging valleys are frequently truncated into triangular facets. Which of the following Statements is/are Correct?
1 and 2 are correct
Statement 1 – Correct. Tributary glaciers carve shallower valleys than the main trunk glacier. After deglaciation, these tributary valleys are left perched (hanging) at higher elevations above the floor of the main U-shaped glacial valley, often producing waterfalls.
Statement 2 – Correct. The pre-glacial spurs (interlocking ridges) projecting into the main valley are sheared off by the powerful main glacier, leaving triangular facets / truncated spurs on the valley walls. Hanging valleys are commonly found between these truncated spurs.
Hence, both statements are correct → option C.
