Waterfall (geological term):

Waterfalls are called falling water in geology, that is, rivers fall vertically from the sky when they flow through faults, depressions and other areas. Waterfalls are temporary features during the existence of rivers and will eventually disappear.

Waterfall (Chinese word):

Waterfall is a Chinese word, pronounced as pùbù, which is defined as water flowing down a cliff like a hanging cloth.

The formation of waterfalls:

The main reason for the formation of the waterfall is that the hardness of the rocks at the bottom of the river bed is inconsistent and severely eroded by the impact of the river, while the hard rocks are relatively suspended. When the river flows here, it flies down and forms a waterfall. Waterfalls are a temporary feature. Due to the influence of waterfall drop, water volume, rock type and structure, the waterfall finally disappeared. Waterfall is a sudden vertical drop of flowing river water, which is the main obstacle to the flow of river water. In some cases, the cliffs or scarps of waterfalls are washed away by the current and recede in the upstream direction, while in other cases, the erosion is often downward.

Cut and bevel the whole river including the waterfall. With the passage of time, the combined effect of these factors makes any possible waterfall inevitably disappear. The energy of the river will eventually produce a relatively smooth, concave longitudinal section. Although all waterfalls will die out, at the same time, new waterfalls will be born in the long years. The geological movement of the earth makes mountains and platforms uplift, strata fracture and dislocation, which create conditions for the birth of new waterfalls.

The disappearance of the waterfall:

Where there are waterfalls, the river will always erode upstream, trying to flatten the heights and flatten the river. The faster the water flow, the stronger the erosion to rivers and banks. The river continuously disintegrated the upper part of the waterfall, causing the rock strata to break and fall, so the position of the waterfall gradually retreated upstream, and the fall of the waterfall also decreased. In some cases, the position of the waterfall will fade upstream because the cliff or scarp is washed by the current; In other cases, this erosion tends to go deep and obliquely cut the whole river section including waterfalls. As time goes on, if one or both of these two factors are at work, the waterfall will gradually disappear.

World famous waterfalls:

The three major waterfalls in the world refer to Niagara Falls, Victoria Falls and Iguazu Falls.

Niagara Falls 1:

Niagara Falls was formed when the glaciers in Wisconsin retreated at the end of the last ice age. On the way to the Atlantic Ocean, the water in the newly formed Great Lakes opened a road through the Niagara Cliff. Niagara Falls is famous for its beautiful and precious hydropower.

Niagara Falls is characterized by the formation of Wisconsin glaciers about 10000 years ago. A large number of melting ice sheets (see Algonquin Lake, Chicago Lake, Iroquois Glacial Lake and Planan Sea) filled the carved basins of glaciers, so they are in the Great Lakes because we know them today. Scientists believe that there is an ancient valley near the present Welland Canal, which was buried by glacier drift and became the burial canyon of St. David.

Geology:

When the ice melts, the upper reaches of the Great Lakes flow into niagara river and then rearrange along the terrain of Niagara Cliff. As time goes by, the river cuts the canyon through the cliff facing north or cuesta. Due to the interaction of the three main strata, the erosion of bedrock is not uniform. The top rock layer is composed of limestone and dolomite, which is corrosion-resistant. Hard stone layers corrode more slowly than the underlying materials. The aerial photo on the right clearly shows the hard overburden, Rockport stratum (Middle Silurian), which is located above the waterfall and below the rapids, about the upper third of the high canyon wall. Just below the hard rock, accounting for about two-thirds of the cliff, is a soft and inclined Rochester stratum (Lower Silurian). The formation is mainly composed of shale, but there are also some thin limestone layers. It also contains ancient fossils. Over time, rivers eroded the soft layer supporting the hard layer and weakened the hard cover, while the hard hard layer was replaced by a large number of rocks. This process was repeated countless times, and finally the waterfall was destroyed.

2. Victoria falls:

Victoria Falls is located in the middle reaches of Zambezi River in Africa, and Zambia borders Zimbabwe. Waterfall width1700m, highest point108m. The average annual flow is about 934 cubic meters per second. The Zambezi River flows slowly before it reaches the waterfall. When the waterfall falls, it sounds like thunder. Local residents call it "Mosio Tunia" (meaning "fog of lightning"). The water from Victoria Falls flows into a canyon with a width ranging from 25 meters to 75 meters.

3. Iguazu Falls:

Iguazu Falls is located on the Iguazu River on the border between Argentina and Brazil. It is the widest waterfall in the world. It is a horseshoe waterfall, 82 meters high and 4 kilometers wide, four times the width of Niagara Falls and much wider than Victoria Falls. There are many rocky islands with trees on the edge of the cliff, which makes the Iguazu River fall into about 275 rapids or waterfalls with heights ranging from 60 meters to 82 meters. 165438+ During the rainy season from 10 to March of the following year, the maximum discharge of the waterfall can reach 12750 m3/s, with an average annual rate of about1756m3/s. ..
