Fault-block mountain of the tilted type. [16] Sierra Nevada Mountains (formed by delamination) as seen from the International Space Station. When a fault block is raised or tilted, a block mountain can result. [17] Higher blocks are called horsts, and troughs are called grabens. A spreading apart of the surface causes tensional forces.
A triangular crest runs the length of its top. The boulder is balanced on three smaller stones roughly 1 m (3 ft 3 in) in diameter that raise it above the bedrock by about 0.5 m (1 ft 8 in) at its lowest point. The point of contact between the boulder and its support stones forms an approximate 3-4-5 triangle.

The name comes from the German word fliessen, which means to flow, because Studer thought flysch was deposited by rivers. The insight that flysch is actually a deep marine sediment typical for a particular plate tectonic setting came only much later. [5] The name flysch is currently used in many mountain chains belonging to the Alpine belt.
Sedimentary rocks are formed through the gradual accumulation of sediments: for example, sand on a beach or mud on a river bed. As the sediments are buried they get compacted as more and more material is deposited on top. Eventually the sediments will become so dense that they would essentially form a rock. This process is known as lithification.
The name Blencathra is likely derived from the Cumbric elements *blain ‘top, summit’ and cadeir ‘seat, chair’, meaning ‘the summit of the seat’. [1] Andrew Breeze has proposed an alternative interpretation of the second element of the name, arguing that it represents a Cumbric cognate of Middle Welsh carthwr ‘working horse’. [2]
Moro Rock is a dome-shaped granite monolith.Common in the Sierra Nevada, these domes form by exfoliation, the spalling or casting off in scales, plates, or sheets of rock layers on otherwise unjointed granite.
