Any sudden drop of water from a higher level to a lower level is called a waterfall.

If it is a large waterfall, it's called a cataract.

Iguazu Falls is a cataract with cascades. SOME OTHERS ARE:

• Niagara Falls
• Victoria Falls (on the Zambezi River in Africa)

If it is a small waterfall, or a series of small waterfalls over steep rocks, it's more likely to be called a cascade.

EXAMPLES ARE:

• St. Anthony Falls on the Mississippi in Minneapolis, Minnesota
• Yosemite Falls in California the tallest falls in North America (2,425 feet)
• The Krimml in Austria

Angel Falls in Venezuela is the world's tallest uninterrupted water fall dropping 979 meters (3212 feet)
