The world’s largest waterfall is underwater! Beneath the Denmark Strait (which separates Iceland and Greenland), frigid water from the Greenland Sea meets warmer water from the Irminger Sea. The cold, dense water quickly sinks below the warmer water and plunges 11,500 feet straight down, flowing at 123 million cubic feet per second. The Denmark Strait Cataract dwarfs any giant waterfall you could find on land. Angel Falls in Venezuela, the tallest waterfall above sea level (3212 feet high), is three times shorter than the Denmark Strait cataract, and Niagara Falls carries 2,000 times less water, even during peak flows.
