Arêtes can also form when two glacial cirques erode headwards towards one another, although frequently this results in a saddle-shaped pass, called a col. [2] The edge is then sharpened by freeze-thaw weathering , and the slope on either side of the arête steepened through mass wasting events and the erosion of exposed, unstable rock. [ 3 ]
On the narrowest sharpest side of the bend, there is faster moving water so this side tends to erode away mostly. Rapid erosion by a large river can remove enough sediments to produce a river anticline , [ 27 ] as isostatic rebound raises rock beds unburdened by erosion of overlying beds.
Firth – Scottish word used for various coastal inlets and straits; Fjard – Glacially formed, broad, shallow inlet; Fjord – Long, narrow inlet with steep sides or cliffs, created by glacial activity; Geo – Inlet, a gully or a narrow and deep cleft in the face of a cliff; Gulf – Large inlet from the ocean into the landmass List of gulfs
This effect helps to erode, smooth and polish rocks. The definition of erosion is grinding and wearing away of rock surfaces through the mechanical action of other rock or sand particles. According to the IPCC, sea level rise caused by climate change will increase coastal erosion worldwide, significantly changing the coasts and low-lying ...
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
The alcoves erode further into the formation eventually meeting underneath the harder caprock layer, thus creating an arch. The erosional processes exploit weaknesses in the softer rock layers making cracks larger and removing material more quickly than the caprock; however, the caprock itself continues to erode after an arch has formed, which ...
