contrary to popular belief, BBM does not stand for 'BlackBerry Messenger'; it bears a slightly more disturbing meaning. BBM is actually short for 'Big Black Meat', or so some Twitter users seem to think (one example being @BigBlackMeatMan). The abbrevaition is almost always used with the name Darelle, for reasons unknown. One thing is for sure, and it's that this word causes great confusion in the Twitterverse.
By Jennifer Kennedy. The Mariana Trench (also called the Marianas Trench) is the deepest part of the ocean. This trench lies in an area where two of the Earth's plates-the Pacific Plate and the Philippine Plate-come together. The Pacific plate dives under the Philippine plate, which also partially gets pulled along (read more about this collision under oceanic-oceanic convergence here).
The Mariana Trench (or Marianas Trench) is the deepest known submarine trench, and the deepest location in the Earth's crust itself.It is located in the floor of the western North Pacific Ocean, to the east of the Mariana Islands at 11Â° 21' North latitude and 142Â° 12' East longitude, which is near Japan.aking into account its latitude and the Earth's equatorial bulge, this puts it at 6366.4 km from the centre of the Earth. The Arctic ocean, on the other hand, is ~4 km deep, which would put its floor at ~6352.8 km from the Earth's centre, 13.6 km closer.
