The tallest waterfall on Earth is, surprisingly, underwater. The Denmark Strait Cataract, between Greenland and Iceland, falls around 11,500 ft / 3,505 m… several times farther than any on land. Cold water from the north sinks below warmer water, rushing down an underwater ridge. Here are the ten tallest waterfalls on land, measured in feet and meters:

1. Angel Falls, Venezuela: 3,212 ft (979 m)
2. Tugela Falls, South Africa: 3,110 ft (948 m)

4. Oloʻupena Falls, Hawaii (US): 2,953 ft (900 m)
5. Yumbilla Falls, Peru: 2,940 ft (896 m)
6. Skorga, Norway: 2,871 ft (875 m)
