The tallest waterfall on Earth is, surprisingly, underwater. The Denmark Strait Cataract, between Greenland and Iceland, falls around 11,500 feet / 3,505 meters… 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:

1. Angel Falls, Venezuela: 3,212 feet / 979 meters
2. Tugela Falls, South Africa: 3,110 feet / 948 meters
3. Tres Hermanas Falls, Peru: 2,999 feet / 914 meters
