A waterfall is a place where flowing water rapidly drops in elevation as it flows over a steep
region or a cliff. Waterfalls are commonly formed when a river is young. At these times the
channel is often narrow and deep. When the river courses over resistant bedrock, erosion
happens slowly, while downstream the erosion occurs more rapidly.
                         Waterfall is grouped into ten broad classes based on the average volume of water present on the fall using a logarithmic scale. Types of waterfalls: block, cascade, cataract, fan, horsetail, plunge,
punchbowl, segmented, tiered, multi-step.
                           The highest waterfall in the world is the Angel Falls in Venezuela. Angel Falls drops 3,212 feet (979 meters) from Devil Mountain in Venezuela. The waterfall was named for Jimmy Angel, an
American flyer who discovered it in 1935 and crash-landed nearby in 1937.
                             Widest Waterfall – Khone Falls stretch 6.7 miles (10.8 kilometers) across the Mekong River, stopping river traffic at the Laos-Cambodia border. The highest Waterfall in Africa is the Tugela
Falls at 947 meters. It is found in South Africa. Europe’s highest Waterfall, Utigard in Norway,
is 800 meters high. Victoria Falls is the largest \Waterfall in the world and is more than a mile
long. Tugela Falls is the world’s second tallest at 947 m (3110 ft) in KwaZulu-Natal province,
Republic of South Africa.
                            Some Waterfalls are constructed by artificial means indoors. The largest of these is in the lobby of the International Center, in Detroit.
