This erosion can also be caused by moving water. The term faceted spur is also applied to inverted-V rock faces formed by stream, wave, or glacial erosion and, thus, as a synonym for truncated spur.[1][2]. Most DDS systems are designed so that the phase truncation spurs are less than the DAC spurs. Truncated spurs can be found within mountain ranges, along the walls of river valleys, or along coastlines. e.g. Major features created by glacial erosion include corries, artes, pyramidal peaks, truncated spurs, glacial troughs, ribbon lakes and hanging valleys. A U- shaped valley is also referred to as a glacial trough, and it is a valley that is eroded glacially. Interglacials, on the other hand, are periods of warmer climate between glacial periods. .

Industrial Spur Gear in GOREGAON (W) Industrial Spur Gear. Glacier can also shape landscapes by depositing rocks and sediment. U-shaped valleys, fjords, and hanging valleys are examples of the kinds of valleys glaciers can erode. Hanging valleys are the glacial landforms formed when a glacier passes through a main valley with massive erosional power. This approximation is extremely useful in the applications of mathematics, for example in truncating Taylor series. How are hanging valleys and truncated spurs formed? As the ice melts they get filled up with water and become beautiful lakes in the mountains.
