The Atlantic Ocean has a long and indented coastline. In an indented coastline, water comes close to the harbor providing a large entrance to the ships. Thus, the Atlantic Ocean is the busiest ocean, as most of the trade between the countries of the world occurs through this ocean. North America and South America are located to its west and Europe and Africa are located to its east. Owing to the strategic location of the Atlantic Ocean, a lot of trading is carried out through it. The North Atlantic Ocean is the busiest route.
