Did You Know: Mariana Trench

Did you know? — By on 2011/10/17 5:05 AM

Did you know that the pressure at the deepest point in the ocean is more than 11,318  tons/sq m, or the equivalent of one person trying to support 50 jumbo jets?

And did you know that the deepest part of the world’s oceans is Mariana Trench?

It is located in the western Pacific Ocean, to the east of the Mariana Islands. The trench is about 2,550 kilometres (1,580 mi) long but has a mean width of only 69 kilometres (43 mi).

It reaches a maximum-known depth of about 10.91 kilometres (6.78 mi) at the Challenger Deep, a small slot-shaped valley in its floor, at its southern end, although some unrepeated measurements place the deepest portion at 11.03 kilometres (6.85 mi).

If Mount Everest, the highest mountain on Earth at 8,850 metres (29,040 ft), was set in the deepest part of the Mariana Trench, there would be 2,060 metres (6,760 ft) of water left above it.
