Interesting Facts About Waterfalls: Charismatic Waterfall Video!

A waterfall is typically a river or any other body of water steep naturally fall over a rocky ledge into the plunge pool below it. Waterfalls are also known as cascades. The wearing away of Earth, the process of erosion, plays a very crucial role in the formation of waterfalls. Also, waterfalls themselves contribute to erosion. Usually, waterfalls form as streams flow from soft rock to hard rock. This occurs both vertically (as the stream drops in a waterfall) and laterally (as the stream flows across the land). In these cases, the soft rock erodes, leaving a very rocky ledge over which the stream falls. A fall line is an imaginary line along which parallel rivers always plunge as they flow from uplands to lowlands. Several waterfalls in a particular location assist hydrologists and geologists determine a location’s fall line and underlying rock structure.
waterfallWaterfalls also establish where meltwater drops over an edge of an ice shelf or tabular iceberg. It’s believed that the underwater waterfall-the Denmark Strait cataract- is the biggest waterfall by all measures with a drop of 3,500 m (11,500 feet) and a flow rate beyond 5.0 million cubic meters (175 million cubic feet) per second, making it 350 times as voluminous as the nonexistent Guairá Falls on the border of Paraguay and Brazil that was once believed to be the top voluminous waterfall in the world.
Waterfalls are usually formed in the higher course of the river. At these periods, the channel is usually deep and narrow. When the river flows over any resistant bedrock, erosion occurs gradually, while downstream the erosion happens more quickly. As the watercourse rises its velocity at the edge of a waterfall, it removes the material from the riverbed. Whirlpools developed in the turbulence as well as stones and sand carried by the watercourse raise the erosion volume. This results in the waterfall to carve more deep into the bed and also recede upstream. Usually, over time, the waterfall will eventually recede to develop a canyon or gorge downstream while it recedes upstream, and it’ll carve deeper into the ridge directly above it. The rate of retreat for a particular waterfall can be as high as 1 ½ meter annually.
Usually, the rock stratum just under the highly resistant shelf will be of a softer kind that means undercutting because of splashback will take place here to create a shallow cave-like creation called a rock shelter behind and under the waterfall. Finally, the outcropping, highly resistant cap rock will fail under pressure to add some blocks of rock to the base of a waterfall. The blocks of rock are now broken down into small boulders by attrition while they collide with each other. Also, they always erode the base of a waterfall by abrasion, forming a deep gorge or plunge pool.
Streams become shallower and broader just above waterfalls because of flowing over the rock shelf, and there’s often a deep area just under the waterfall due to the kinetic energy of the water volume hitting the bottom. Waterfalls generally form in a rocky place due to erosion. After a long time of being totally formed, the water volume falling off the ledge will finally retreat and cause the horizontal pit to parallel to the wall of a waterfall. Ultimately, as the pit increases in depth, the waterfall will collapse to be substituted by a sharply sloping stretch of the river bed. On top of slow processes like erosion, earth movement as a result of earthquakes or volcanoes or landslides can cause a differential in heights of land that interfere with the normal course of a water flow, and create waterfalls.

Fun Facts about Different Types of Waterfalls
1. Type can categorize waterfalls. There are numerous types of waterfalls, and it is possible for a waterfall to suit more than one category.
2. Ledge (Curtain, Classical) waterfalls usually descend vertically over a cliff maintaining its partial contact with the bedrock.
3. Block (sheet) waterfalls descend from a broad river or stream. For example, Niagara Falls in the United States.
4. Cascade waterfalls descend over multiple rock steps; they are often a relatively safe kind of waterfall e.g. Monkey Falls, in India.
5. Cataracts waterfalls are broad, powerful and usually dangerous. An extremely wide and wild cataract falls is Iguazu River at the Argentina and Brazil border.
6. Chute waterfalls force a tremendous amount of water through thin vertical passages at a high pressure e.g. Three Chute Falls, Yosemite National Park, US.
7. Frozen waterfalls will eventually freeze over for the short period of the year. Mountaineers usually test their skills by only climbing frozen waterfalls e.g. The Fang, Vail, Colorado, US.
8. Horsetail waterfall will easily maintain contact with the bedrock underneath them.
