Home to some of the most magnificent marine life and the richest fishing resource, it is also an environment with an abundance of natural gas fields as well as petroleum deposits.
On average, the overall depth of the Atlantic Ocean is approximately 3,339 metres deep, with the ocean floor being quite flat, except where the 4 deep trenches reside.
