What are " Truncated Spurs"? Where and how are they formed?

( 150 words, 10 marks)

Answer. 

Truncated Spurs are erosional landforms found in glaciated regions. 

Truncated Spurs


Location:

Truncated Spurs are commonly found in regions where glaciation occurs. 

They are commonly triangular-shaped and found in between Hanging Valleys. 

They are mainly found in U-shaped valleys of the Alps, Rockies, Himalayas, Alaska, and Siberia.


Formation:

When glaciers move, they carve out eroding the rock and soil.

The glacier movement abrases the valley's wall and pulls away chunks of rock, resulting in the Truncation of Spur.


Truncated Spurs are important for understanding past glacial activity and landscape evolution.
