Waterfall is a water curtain formed by the sudden fall of water from a steep cliff. The sound is deafening and magnificent. Waterfalls are formed for many reasons. For example, the vertical movement of the crust leads to the relative rise and fall of faults, forming cliffs, and rivers will form waterfalls when they pass through these places.
In addition, in the river bed, because the rock structure of each river bed is different, the ability to resist river erosion is also different, so the topography of the river bed will be different. This is also a reason for the formation of waterfalls. In addition, natural effects such as glaciers, volcanic topography, coastline erosion and underground rivers will also form waterfalls.
