As a very spectacular geological landscape, the waterfall is very popular no matter which country. Waterfalls are also tourist attractions that people like to watch.
There are many existing waterfalls in the world today, which are loved by people. Many waterfalls have also existed for a long time.
The waterfall was a flowing river suddenly falling vertically, and it was the main blockage in the flow of the river.
There are many reasons for the formation of waterfalls in the world. In the same river, due to the different rock structures of the river bed, the soft places are easily eroded, and the hard places are eclipsed slowly.
At the junction of soft and hard rocks, the height difference between the river bed is very large, so the waterfall will appear.
After the volcanic eruption, the water of the volcano accumulated into a lake, and the lake water overflowed from the gap, which would also form a waterfall.
The volcanic eruption of magma hinders the river, causing the lake to come out, and also form a waterfall.
Waterfalls are not forever. Where there is a waterfall, the river is always eroding upstream.
The upper part of the waterfall is continuously broken, causing the rock layer to rupture and whereabouts. In the end, the location of the waterfall will gradually decline in the upstream direction, and the gap between the waterfall is getting smaller and smaller.
After a long time, the cliff will be destroyed by the flowing water, and any large waterfall will eventually disappear.
With the disappearance of the waterfall, the surrounding ecology will be damaged to a certain extent with the continuous erosion of the terrain.
Many animals will have to migrate due to the lack of food, and even the number will decrease sharply.
In fact, many large waterfalls on the planet have an obvious retreat, such as Niagara Falls.
Today, the gap between Niagara Falls is about 50 meters. According to the surrounding rock formations, we can infer that the previous position of Niagara Waterfall is at the lower reaches, and the gap may be 100 meters.
Now, the waterfall has retreated more than 1 meter upstream each year, and the gap is decreased.
At this speed, Niagara Falls will disappear completely after 50,000 years.
Let's get to know some famous waterfalls in the world.
U.S., Havasu Waterfall
The color of the Havasu Waterfall looks like another world. Have Su Waterfall is composed of orange rocks and sky-blue pools. The dynamic color of the water is attributed to the calcium carbonate in the water.
Switzerland, Rhine Waterfall
The most powerful waterfall in Europe looks like roaring from fairy tales. Rhine Waterfall is located upstream of the Rhine. Rhine Waterfall slowly flows from a height of 255 meters, but this scene can only be seen in March and April.
Brazil, Higuasu Waterfall
Iguazu Waterfall is the largest waterfall system in the world and of course one of the most awesome landscapes. This waterfall system includes more than 270 waterfalls, with a total length of 2.7 kilometers.
It spans the border between Brazil and Argentina and flows in the staircase.
