There are several famous places in the world where two oceans or seas meet but their waters don’t immediately mix, creating a striking visible boundary. One well-known example is where the Atlantic Ocean meets the Arctic Ocean near Greenland. The difference in temperature, salinity, and density causes the waters to stay separate for some distance before gradually blending.

This natural phenomenon can also be seen at places like the meeting of the Gulf of Alaska and the Pacific Ocean. These ocean boundaries affect marine life and currents, creating unique ecosystems. Observing where waters don’t mix reminds us of the complexity of Earth’s oceans and how different water bodies interact in fascinating ways. Shutdown123
