Did you know that the Earths longest mountain range
is underwater? The Mid-Ocean Ridge system, shown above snaking
its way between the continents, is more than 56,000 kilometers
(35,000 mi) long. This series of mountains and valleys marks
the areas where the Earths crustal plates are moving
apart. This is where most hydrothermal vents are located.
The University of Delawares Extreme
2000 deep-sea dive site is in a vent field in the Sea
of Cortés off the west coast of Mexico. Map
