True or false: The Mariana Trench is deeper than Mount Everest is tall.

True. From NOAA: "The Mariana Trench measures more than 1,500 miles (2,550 kilometers) long and 43 miles (69 kilometers) wide on average. If you cut Mount Everest off at sea level and put it on the ocean bottom in the Challenger Deep, there would still be over a mile of water over the top of it."
