LAS ESPUELAS (The Spurs) Instr. A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. As ice and glaciers move, they scrape along the surrounding rock and pull away pieces of rock which causes erosion. Hanging valleys are found in between truncated spurs as they join the main glacial valley from the side. Answer:Cirque Glacier. The longitudinal profile sometimes reveals steps down the valley indicating rock (possibly less jointed or much harder) that resisted abrasion. 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. Most online reference entries and articles do not have page numbers. The snow compacts into ice and this accumulates over many years to compact and grow into a corrie/cirque glacier.

[1][2], A faceted spur is also a spur that ends in a triangular face, known as a triangular facet, with a broad base and an apex pointing upward. Types of spurs include interlocking spurs and truncated spurs. eg. The passage of glacial ice over underlying bedrock often results in asymmetric erosional forms as a result of abrasion on the stoss (upstream) side of the rock and plucking on the lee (downstream) side. They are formed when glaciers move through the main valley and cut off spurs. Required fields are marked *. Major features created by glacial erosion include corries, artes, pyramidal peaks, truncated spurs, glacial troughs, ribbon lakes and hanging valleys.
