Undersea Waterfalls and Density

The largest waterfall on Earth is located underwater in the Denmark Strait, between Greenland and Iceland. It is formed by cold, dense water from the Nordic Seas sinking below warmer North Atlantic water, creating a waterfall over an undersea mountain called a cataract. This underwater waterfall is over three times taller than Angel Falls and has a water flow rate 130 times greater than the largest land waterfalls.
