Facts about water’s power
36. The largest waterfall on earth carries 123 million cubic feet of water per second—and is underwater.
While Angel Falls in Venezuela is often called the largest land-based waterfall, the underwater Denmark Strait cataract is the planet’s biggest waterfall. It’s caused by differing water temperatures flowing over a huge, 11,500 ft drop on the seabed (earthsky.org).
37. The Mississippi River has the fourth largest watershed in the world, covering 40% of the continental US.
The river releases over 16,000 cubic meters of water into the Gulf of Mexico every second.
38. The Marianas Trench in the Pacific ocean has an atmospheric pressure of around 1000 times that of sea level.
At this pressure, which is equivalent to eight tons for every square inch, even water itself takes on a different, more ice-like structure (nasa.gov).
39. Hydropower plants convert water’s potential energy to kinetic energy, then from mechanical energy to electrical energy.
Most hydroelectric plants use large reservoirs and dams to generate kinetic energy in water as it’s released and falls (waterpowercanada.ca).
40. There are 321,003,271 cubic miles of water in the Earth’s oceans.
This is equivalent to around 352 quintillion, or 352,000,000,000,000,000,000, gallons of water (oceanservice.noaa.gov).
