Oceanic passages are natural routes across the world's oceans that facilitate navigation and maritime trade. These passages are crucial for connecting different regions and countries, allowing for the movement of goods, people, and information. Examples include the Strait of Gibraltar and the Bering Strait, which serve as important links between major bodies of water. These routes are often influenced by factors such as weather patterns, ocean currents, and geopolitical considerations. Understanding oceanic passages is essential for shipping industries and environmental studies, as they play a significant role in global commerce and marine ecosystems.
