Question: How deep is the Atlantic Ocean? Answer : The second-largest ocean on our planet, the Atlantic Ocean has some pretty deep spots. The average depth of this ocean is 3,660 meters. For comparison, a skyscraper like the Empire State Building in New York is only 381 meters tall. Imagine how many buildings you'd have to stack on top of each other to reach from the bottom of the ocean to above the waves! The very deepest part of the Atlantic is called the Milwaukee Deep. This area is just north of Puerto Rico and is about 8,530 meters deep. But the deepest spot in the whole world is in the Pacific Ocean.
