This happens both laterally and vertically. In every case the soft rock erodes and leaves the hard rock as it is. Over this a stream falls. The fall line is an imaginary line along which parallel rivers plunge while flowing from uplands to low lands. Many waterfalls in this way help the geologists determine a region's fall line and underlying rock structure. As the stream flows it carries various amounts of sediments- be it microscopic silt, pebbles or boulders. Sediments erode the beds of soft rocks like sandstone or limestone.
The stream then cuts the beds so deep that only hard rocks like granite are left. Waterfalls develop as the granite formations form cliffs and ledges. The stream's erosion increases near the base as velocity increases of the rivers. The movement of water at the top can erode the rocks to be flat and smooth. This way the plunge pool is formed at the base. Delving deep into this topic to try to gain an understanding is beyond the scope of our discussion.
So now that you have an idea of the basic principles behind waterfall formation, you may notice that you can leverage this information to predict where you can find waterfalls around the world.
For example, you know that you need hard rock layers to have the kind of terrain favorable for waterfalls. On top of the geology, you need to go where it tends to get reliable rain or snowmelt to feed the watercourses that ultimately drop over these hard rock layers. It also suggests that you can even time your visits if you know that there are pronounced wet and dry seasons. You must be logged in to submit content.

November 17, pm by Dale - Do waterfalls ever develop along fault lines where the earth has shifted vertically? Read More. Most waterfalls fit more than one category. A block waterfall descends from a wide stream.
Niagara Falls, in the U. A cascade is a waterfall that descends over a series of rock steps. The waterfall is safe enough for children to play in the water. A cataract is a powerful, even dangerous, waterfall.
Among the widest and wildest of cataracts are the thundering waters of the Iguazu River on the border between Brazil and Argentina. A chute is a waterfall in which the stream passage is very narrow, forcing water through at unusually high pressure.
Fan waterfalls are named for their shape. Water spreads out horizontally as it descends. Frozen waterfall s are just what they sound like. For at least part of the year, the waterfall freezes. Mountaineer s often climb frozen waterfalls as a challenging test of their skill.
The Fang is a single pillar of ice in Vail, Colorado that vertically plunges more than 30 meters feet. Horsetail waterfalls maintain contact with the hard rock that underlies them. Reichenbach Falls, a fall on the Reichenbach Stream in Switzerland, is a horsetail waterfall where legendary detective Sherlock Holmes allegedly fell to his doom. Multi-step waterfalls are a series of connected waterfalls, each with their own plunge pool. The breathtaking "falling lakes" of Plitvice Lakes National Park, Croatia, are a series of multi-step waterfalls.
Plunge waterfalls , unlike horsetail falls, lose contact with the hard rock. The tallest waterfall in Japan, Hannoki Falls, is a plunge waterfall that stands meters 1, feet. Hannoki Falls is seasonally fed by snowmelt from the Tateyama Mountains. Punchbowl waterfalls are characterized by wide pools at their base. Wailua Falls is a punchbowl waterfall on the island of Kauai, Hawaii.
Although the plunge pool is tranquil and popular for swimming, the area around Wailua Falls itself is dangerous. The water flowing over segmented waterfalls separate as distinct streams. Huge outcroppings of hard rock separate the streams of Nigretta Falls, a segmented waterfall in Victoria, Australia, before they meet in a large plunge pool.
The Niagara River has two falls, one in the U. Each waterfall is less than 60 meters feet tall, but together they are more than a kilometer. Niagara and many other falls with large volumes of water are used to generate hydroelectric power. A tremendous volume of water flows over Niagara Falls, as much as 5, cubic meters , cubic feet per second. Power stations upstream from the falls convert hydroelectric energy into electricity for residential and commercial use.
