When a sharp irregularly shaped rock falls into a river, it typically begins to be smoothed and rounded over time due to the constant flow of water and the movement of sediment. The water erodes the rock's sharp edges and corners, gradually changing its shape. Additionally, the rock may become embedded in the riverbed or transported downstream, depending on the river's current and the rock's size and weight. This process is a part of the natural cycle of erosion and sedimentation in river ecosystems.
A crescent-shaped lake formed by a river meander is called an oxbow lake. It occurs when a meandering river cuts off a meander bend, forming a U-shaped body of water separated from the main river channel. Oxbow lakes are often found in flat landscapes and are a natural part of a river's evolution.
It is called a delta.
A fan-shaped deposit at the mouth of a river is known as a delta. Deltas form when a river flows into a larger body of water, like a sea or ocean, and deposits sediment and other material it has carried downstream. Deltas are typically characterized by their flat, triangular shape.
Iguazu Falls (The Devil's Throat). Iguazu Falls is located on the Iguassa or Iguaça River on the border of Brazil and Argentina. Iguazu is composed of an impressive set of nearly 300 waterfalls all plunging over the border between two countries. In total the falls are over 492 feet long, although the cliff from which the water falls is up to 2.5 miles long and at its tallest falls reaches heights of 269 feet. Iguazu is a wide horseshoe shaped set of falls, some would call it crescent shaped, surrounded by thick green jungle forests filled with bamboo and palm trees. The river before it hits the falls is meandering over the Parana Plateau in its attempt to make it to sea level. Most of the Iguazu Falls are cascade waterfalls and in the process of falling they send up lots of mist which prisms the daylight creating lots of rainbows to dazzle the observer. Its said that the sound of the falls can be heard from miles away. In fact one of its waterfalls is called, 'Garganta del Diablo' or Devil's throat may hearken from the thunderous roaring of the falls. This area of the falls is particularly tumultuous, sending a spray of water high over the cliff and is thought to be the home of the river's god. The name Iguazu comes from the local Guarani language, which is 'y guasu' or big water.
The different types of river valleys include V-shaped valleys, U-shaped valleys, and canyon valleys. V-shaped valleys are typically narrow with steep sides, carved by erosion from a river. U-shaped valleys are wider and have more gradual slopes, formed by glaciers. Canyon valleys are deep and narrow with steep sides, often formed by a combination of tectonic activity and erosion.
