All the water on land flows from high to low.Because the steeper the ground, the faster the water flows.And in places where the terrain is high and low and the terrain is shifting, water suddenly falls from the top, creating a waterfall.
In many famous mountains and rivers in our country, there are waterfalls in many places.For example, the famous huangguoshu waterfall in guizhou province has a huge curtain of water up to 75 meters high. After the water falls down, it forms white spray, then turns into water mist, and then sends out a roaring sound. The scene is very spectacular!
The formation of a waterfall must have water, and it must have a variety of terrains that vary steeply from high to low.Why did this form of terrain?
Because the earth's crust is moving.The earth's crust would break, and the rocks on either side of the fault would rise and fall, creating steep rock walls.So when the river passes over the steep cliff, it falls down naturally, forming a waterfall.
Since the eruption, a crater has been left at the top of the volcano.If the water into a lake, the water will overflow, there may also be a place outside the crater of the waterfall.For example, the waterfall in baitou mountain is formed by this way.In addition, lava from a volcano, or landslides caused by an earthquake, blocks the river and creates a natural dam that not only raises the head of the water, but also overflows and becomes a waterfall.
In addition, the bed of a river is made of different rock properties, hard and soft, so their ability to resist the erosion of water is not the same, hard rock resistance is stronger, not easy to be eroded;Soft rocks are less resistant to erosion.So there are differences in the topography of the river bottom, and the formation of steep cliffs on the channel, which is also an important reason for the formation of the waterfall.
In some areas of the ancient distribution of glaciers, differences in the depth of ancient glacial erosion left a "u-shaped" valley of glaciers of different depths, which was later occupied by rivers, so that water flowed through the junction of valleys of quite different depths, thus forming a waterfall.
On some shores, where rivers flow into the ocean, they are shortened by the violent waves that often beat the shore and force it to "recede."If the coast is destroyed fairly quickly, the bottom of the river, which used to rise above the sea, will also be "inverted" on the shore, and the river will form a waterfall where it enters the sea.
Moreover, in limestone regions there are often subterranean rivers, and where they flow, if the terrain changes abruptly;Or a dark river flowing from a steep cliff, which makes the falls even more spectacular.
All the water on land flows from high to low.Because the steeper the ground, the faster the water flows.And in places where the terrain is high and low and the terrain is shifting, water suddenly falls from the top, creating a waterfall.
