Waterfalls are sometimes interchangeably referred to as "cascades" and "cataracts", though some sources specify a cataract as being a larger and more powerful waterfall [1] [4] [5] and a cascade as being smaller. [6] A plunge pool is a type of stream pool formed at the bottom of a waterfall. [7] A waterfall may also be referred to as a "foss ...
Cataract: A large, powerful waterfall. [1] Multi-step: A series of waterfalls one after another of roughly the same size each with its own sunken plunge pool. [1] Block: Water descends from a relatively wide stream or river. [1] [2] Cascade: Water descends a series of rock steps. [1] [2] Segmented: Distinctly separate flows of water form as it ...
The falls form when seawater rushes through two short and narrow gorges which are about 300 metres (1,000 ft) apart from each other. They are located in the coastal McLarty Ranges situated within Talbot Bay (Ganbadba) within the Buccaneer Archipelago. The seaward gap is about 20 metres (70 ft) wide and the landward one is about 10 metres (30 ft).
The staircase character of the falls consists of a two-step waterfall formed by three layers of basalt.The steps are 35 and 40 metres (115 and 131 ft) in height. The columnar basalt rock sequences are part of the 1,000-metre-thick (3,300 ft) Serra Geral formation within the Paleozoic-Mesozoic Paraná Basin.
The falls are formed where the full width of the river plummets in a single vertical drop into a transverse chasm 1,708 metres (5,604 ft) wide, carved along a fracture zone in the basalt plateau. The depth of the chasm, called the First Gorge, varies from 80 metres (260 ft) at its western end to 108 metres (354 ft) in the centre.
The waterfall has been known as Angel Falls since the mid-20th century; they are named after Jimmie Angel, a U.S. aviator, who was the first person to fly over the falls. [3] Angel's ashes were scattered over the falls on 2 July 1960.
Plunge pools are formed by the natural force of falling water, such as at a waterfall or cascade; they also result from man-made structures such as some spillway designs. [3] Plunge pools are often very deep, generally related to the height of the fall, the volume of water, the resistance of the rock below the pool and other factors. [4]
River rejuvenation can lead to a number of changes in landscape. These include the formation of waterfalls and rapids, knick points, river terraces and incised meanders. [1] Rejuvenated terrains usually have complex landscapes because remnants of older landforms are locally preserved.
