How Is a Waterfall's "Height" Measured?
A waterfall's height is sometimes measured as the single uninterrupted "drop" where the water falls without breaking, and sometimes as the combined total height of a multi-tiered waterfall — which is why the same waterfall can rank differently depending on the measurement standard used.
Some Waterfalls Are Famous for Volume, Not Height
Waterfalls like Niagara Falls show that a waterfall's reputation isn't determined by height alone — despite its relatively modest height, its sheer volume of water has made it world-famous.
Frequently Asked Questions
What is the world's tallest waterfall?
By uninterrupted single-drop height, Angel Falls in Venezuela (about 979 m) is widely recognized as the world's tallest waterfall.
Why do waterfalls sometimes form and disappear over time?
Waterfalls form where a river meets a fault line or a boundary between rock layers of different hardness, and as erosion continues over time, a waterfall's position or shape can gradually shift or even disappear entirely.
