Depth of the Mariana Trench

Why is the Mariana Trench so deep?

In 2003, the journal "Earth and Planetary Science Letters" published an article by six authors, entitled "Why is the Challenger Deep so deep?"

The Challenger Deep is the deepest part - as far as known - of the Mariana Trench. A journal is a magazine in which scientists write articles to tell each other what kind of work they have done (they do not get paid for those articles because writing is part of their job).

Abstracts are available on the web, for instance, here (at Ingenta - a large literature database) and here (at Elsevier, the publishing company of the article). I cannot post these abstracts here either.

More later!
