What seas and oceans wash South America?

From the north, South America is washed by the Caribbean Sea, belonging to the Atlantic Ocean basin, from the east by the Atlantic Ocean, from the west by the Pacific Ocean.
There are high mountains located in the west of the mainland, so air masses from the Pacific Ocean cannot penetrate deeply into the territory of South America, therefore the Atlantic Ocean has a greater influence on the climate of the mainland.
Off the western coast of South America, there is the cold Peruvian current, the east-east warm Guinea and Brazilian currents, and the cold Falklands currents. The cold current prevents the formation of clouds and precipitation, and the warm one favors.
