Hole In Earth's Crust Defies Evolution

A team of British scientists has set sail on a voyage to examine why a huge chunk of the earth's crust is missing, deep under the Atlantic Ocean -- a phenomenon that challenges conventional ideas about how the earth works.
The 20-strong team aims to survey an area some 3,000 to 4,000 metres deep where the mantle the deep interior of the earth normally covered by a crust kilometres thick is exposed on the sea floor.

Experts describe the hole along the mid-Atlantic ridge as an "open wound" on the ocean floor that has puzzled scientists for the five or so years that its existence has been known because it defies existing tectonic plate theories of evolution.
