Located in the small area of the ocean between Greenland and Iceland, this ginormous waterfall is known as Denmark Strait Cataract is 100 miles broad. It stretches 11,500 feet straight from Greenland sea to the Irminger sea carrying 175 million cubic feet of water per second. You should now probably make out why this is the largest waterfall in the world. Angel Falls, the tallest waterfall above the sea is three times shorter than the Denmark Strait whereas Niagara falls carry 2000 times less water even in the peak flows.
The most interesting fact about the Denmark Strait is that even with such a massive flow of water under the sea, the seawater has managed to be very dynamic with varied temperature, salinities and water of different densities thus making it look like any other sea.
The Denmark Strait is formed by the difference in the temperature of the super cold Arctic waters meeting with not so cold water of Irminger sea. The molecules in the cold water are slightly less active than and take up less space than warm water. The molecules in the warm water are packed more closely making the warm water denser and thus it slides down right to the bottom of the ocean.
Mother nature has never let us feel less astonished, isn’t it?
The water in the Denmark Strait doesn’t just sit at the bottom once it reaches there. It forms a massive travelling south and flows with the velocity that is 20-30 times more than that of the combined water of all river that flows into the Atlantic. Now isn’t that amazing?
