Parents and Teachers: Please note we are making some internal changes to the site. As a result, the Great American Multiplication Challenge, Spellerz!, Burnside's Billions and couple of other games will not show statistics or return save codes for the next few days. They will be playable, but no data will be saved. They should be fully functional again by the end of the week. As always, please support this site by following me on FACEBOOK or TWITTER.

A long, steep-sided depression in the ocean floor.
 

What is an Example of a Trench?

 

Located in the Pacific Ocean, just southeast of the Mariana Islands, Mariana Trench is the deepest point on earth. At 35,798 feet below sea level, Marianas Trench is farther below sea level than Mt. Everest is above it. At the bottom of the Marianas Trench, water exerts a pressure of over a thousand times that of standard atmospheric pressure at sea level. In 1960, the U.S. Naval bathyscaphe (submersible vessel) reached the floor of the Marianas Trench. To the pilots surprise, they found various types of flatfish such as flounders and soles.
