The Mariana trench is the deepest point on planet Earth. At its deepest point it reaches a depth of 36,200 feet deep. That's deep enough to put Mt. Everest in and still have over 2,000 feet to spare! The pressure on the bottom of the trench is 15,750 psi. That is over one thousand times the pressure we feel at sea level. In these extremes you may think that nothing would be able to survive, there are actually animals that can survive in these conditions. One of these animals is the angler fish (picture). The angler fish has lights on it to attract prey because in the depth where it lives there is no light. The Mariana Trench is one of the most extreme environment on the planet.
That's so interesting! I never knew that the Mariana Trench was deeper than Mount Everest is tall (with some extra room). Now I also know what that fish is called in "Finding Nemo".. but I wonder how Marlin and Dory survived at that depth and pressure :)
ReplyDeleteCool! I also didn't realize that Mount Everest could fit into... I didn't realize that there was anything in the ocean that went that far down. Do you know how the fish can have lights on it? Do they light up with electricity? Thanks for the interesting info!
