Splash erosion is generally seen as the first and least severe stage in the soil erosion process, which is followed by sheet erosion, then rill erosion and finally gully erosion (the most severe of the four). [10]: 60–61 [13] In splash erosion, the impact of a falling raindrop creates a small crater in the soil, [14] ejecting soil particles. [4]
Bight – Shallowly concave bend or curve in a coastline, river, or other geographical feature; Blowhole – Hole at the top of a sea-cave which allows waves to force water or spray out of the hole; Blowout – Depressions in a sand dune ecosystem caused by the removal of sediments by wind; Bluff – Tall, near vertical rock face
Soil sloughing is soil falling off banks and slopes due to a loss in cohesion. [1] Soil sloughs off for the same reasons as landslides in general, with very wet soil being among the leading factors. [2] [self-published source] Sloughing is a relatively shallow phenomenon involving the uppermost layers of the soil.

Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
A stratum of erosion-resistant sedimentary rock (usually limestone) found in arid areas. Caprock forms the top layer of most mesas and buttes. [2] cardinal directions The set of four primary directions used in cartography and navigation: north (N), south (S), east (E), and west (W). Together they form the primary divisions of the compass rose.
Other common types of caprock are sandstone and mafic rock. In processes such as scarp retreat, the caprock controls the rate of erosion of the scarp. As the softer rock is cut away, periodically the caprock shears off. Caprock is also found in salt domes and on the top of mesa formations.
The Horseshoe Falls, one of the three Niagara Falls.The falls are a knickpoint, formed by slower erosion above the falls than below. In geomorphology, a knickpoint or nickpoint is part of a river or channel where there is a sharp change in channel bed slope, such as a waterfall or lake.
