Waterfalls may be seen as some of the most beautiful river formations in the world. They are essentially places where the river water drops sharply, due to a sudden change in the river gradient. There are many different types of waterfalls of various forms. There are many notable waterfalls for tourists to visit, and they can be found across the globe. All it takes is a search of notable waterfalls to get a list hundreds of waterfalls worth visiting. For example, the world's tallest water fall, Angel Falls in Venezuela, named a UNESCO heritage site, with water from the Auyantepui Mountain plummeting more than nine hundred metres before continuing into the Kerep River.
There are also the world's most visited waterfalls; the Niagara falls, featured in multiple films. They are a source of hydroelectric power and a huge source of tourism every year, resting partially in Canadian territory, and partially in American territory. There are also the Boyoma falls in Congo, with the highest volume of flow, and ‘Mosi-oa-Tunya' - ‘smoke that thunders' also known as Victoria Falls in Zambia and Zimbabwe, forming what may be the largest waterfall in the world. Other notable waterfalls include the Huangguoshu Waterfall in China, which can be viewed from multiple angles due to the ‘water curtain cave'.
The tallest waterfall in Europe is located in Norway, the ‘Vinnufossen'. The most one can do to ‘preserve' waterfalls, is not to litter and ruin its aesthetic value. The reality is that waterfalls are not permanent structures, over hundreds of years, they are known to naturally ‘cut back', essentially eroding its base at the plunge pool until a section of the top collapses, and the waterfall is ‘moved' further upstream. The process continues and can often result in the formation of an equally stunning gorge or valley.
