Oceans Meet at Cape Horn_ Why?

Oceans Meet at Cape Horn – Why?

Cape Horn, located at the southern tip of South America, is where the Atlantic and Pacific Oceans meet. But surprisingly, they don’t blend right away. This happens because the two oceans have different characteristics—like temperature, salinity (saltiness), and density. The Pacific Ocean is generally warmer and less salty, while the Atlantic is colder and denser. These differences create a kind of "invisible wall" that slows down the mixing of their waters.

When you look at the meeting point, you can sometimes see a visible line separating the two oceans, with each side showing slightly different shades of blue. This striking natural phenomenon is due to a process called oceanic cline, where layers of water with different properties resist mixing. Over time, the waters do blend, but the moment they meet is like watching nature draw a line in the sea.
