Final answer:
The Drake Passage separates the tip of South America from Antarctica and connects the Pacific Ocean to the Atlantic Ocean.
Step-by-step explanation:
The passage that separates the tip of South America from Antarctica and connects the Pacific Ocean to the Atlantic Ocean is known as the Drake Passage. This strait is situated between Cape Horn, the southernmost point of the Tierra del Fuego archipelago of South America, and the South Shetland Islands of Antarctica. It is one of the most significant natural maritime channels, providing a navigable route for ships, although it is often considered difficult to navigate due to the strong ocean currents and occasionally harsh weather conditions.
