Schools in the U.S. Teach that there are FOUR

Have never heard of a "southern" ocean in my LIFE

If you look at the globe there's only 1, cuz they are all connected, but they named areas of that big ocean so people know what they are talking about + the climate/temperature/biodiversity is different in several parts

Pacific
Atlantic
Indian
Arctic
Southern (Antarctic)

Also, being taught that there are 5 is NOT something American/European/whatever, it's worldwide scientific conventions

Four

1, the Antarctic Ocean
