Introducing the new splash of waterfalls. In fact as the waterfalls were formed there is no mystery. They are created each time the streams or rivers run through the edge of steeply landform - the cliffs or very steep cliffs in the river bed. Countless tiny waterfalls fed by melting snow rushing cascades from the mountains around the world. (You may have heard about the chain of mountains in the northwest Pacific coast known as the Cascades.) Some of the largest waterfalls formed by the waters of rivers flowing through the edge of the high plains of the plateau. The highest waterfall in the world Angel Falls in Venezuela rushes down tepui one of many impressive isolated plateau scattered among the tropical forests in northern South America. Falls are usually located in the upper reaches of the river in the hills or mountains. Dunn''s River Falls on in Jamaica - the only known waterfalls which was formed in the estuary. Waterfalls are formed where there is solid rock layers overlying soft rock. Flow of the river passes through various kinds of rocks beneath it. Some of these rocks are quite firm while other rocks are soft and break very easily. River water flowing over layers of solid rock. When they reach the soft rocks the water begins to destroy or erase the soft rock. River has no choice but to plunge hundreds of meters deep into the cliffs until it reaches another layer of solid rock at the bottom. For more than a thousand years of soft rock is destroyed and the river begins to cut into a vertical cliff. This leads to the formation of rock through which water from the river overflows. After a while cliff becomes steeper and deeper forming a waterfall. In this case the basis of the waterfall is formed by a large hollow body of water immersion.
