As the weathered bedrock turns to soil, there is a greater elevation difference between the soil level and the hard bedrock. With the introduction of water and the thick soil, there is less cohesion and the soil flows out in a landslide. With every landslide more bedrock is scoured out and the hollow becomes deeper.
Plucking (glaciation) Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the weathering and erosion of pieces of bedrock, especially large "joint blocks". This occurs in a type of glacier called a "valley glacier". As a glacier moves down a valley, friction causes the basal ice of the glacier to melt and ...
Spheroidal weathering is a form of chemical weathering that affects jointed bedrock and results in the formation of concentric or spherical layers of highly decayed rock within weathered bedrock that is known as saprolite. When saprolite is exposed by physical erosion, these concentric layers peel (spall) off as concentric shells much like the ...
Greenfield is a fictional city created in the sandbox video game Minecraft. As of May 2022, the city is one-fourth complete and has a size of 20 million blocks. [2] The city was started by Minecraft user THEJESTR in August 2011. [3] [4] As of April 2022, there are approximately 1.3 million downloads of the city map. [5]
Joint (geology) Horizontal joints in the sedimentary rocks of the foreground and a more varied set of joints in the granitic rocks in the background. Image from the Kazakh Uplands in Balkhash District, Kazakhstan. Orthogonal joint sets on a bedding plane in flagstones, Caithness, Scotland. Joints in the Almo Pluton, City of Rocks National ...
One of the last stages was the formation of Badwater Basin, which occurred by about 4 Ma. [20] Data from gravimeters show that Death Valley's bedrock floor tilts down toward the east and is deepest under Badwater Basin; there is 9,000 feet (2,700 m) of fill under Badwater. [21]
Nubbin (landform) Nubbins of Karlu Karlu, Central Australia. In geomorphology a nubbin is a small and gentle hill consisting of a bedrock core dotted with rounded residual blocks. [ 1][ 2] The blocks derive from disintegrated and weathered bedrock layers. In particular it is assumed that the boulders of the nubbins are the remnants of the outer ...
A bedrock river is a river that has little to no alluvium mantling the bedrock over which it flows. However, most bedrock rivers are not pure forms; they are a combination of a bedrock channel and an alluvial channel. The way one can distinguish between bedrock rivers and alluvial rivers is through the extent of sediment cover.
