The equator
There is a North and a South Atlantic
The North and South Atlantic Oceans are distinct due to the Earth's geography and tectonic plate boundaries. The equator divides the Atlantic Ocean into two hemispheres, creating the North Atlantic and South Atlantic Oceans. This division is further influenced by ocean currents, climate patterns, and marine ecosystems, which differ significantly between the two regions. Additionally, historical exploration and navigation have contributed to the identification of these two separate areas of the Atlantic.
