It gets to a maximum-known depth involving in relation to 10.91 kilometres (6.78 mi) (35,800 ft) on the Challenger Deep , a smaller slot-shaped area inside it's floor, from it is the southern area of end, although many unrepeated size location the actual deepest percentage at 11.03 kilometres (6.85 mi).

At the underside of the trench, in which the actual system meet, the actual previously mentioned exerts your involving 1,086 cafes (15,750 psi), above a thousand occasions the with sea level.

The trench is not that component to the actual seafloor closest to the center of the actual Earth . This will be because the Earth is not an ideal world : it has the radius is related to 25 kilometres (16 mi) less at your posts in comparison with on the equator.
