The term 'truncated spur' is associated with which one of the following??

a) Aeolian process

b) Fluvial process

c) Glacial process

d) Weathering process

Answer- Glacial Process

Before glaciation, mountain valleys have a characteristic "V" shape, produced by downward erosion by water. However, during glaciation, these valleys widen and deepen, forming a "U"-shaped glacial valley. Besides the deepening and widening of the valley, the glacier also smooths the valley due to erosion. In this way, it eliminates the spurs of earth that extend across the valley. Because of this interaction, triangular cliffs called truncated spurs are formed.
