Natural harbors are sheltered bodies of water that provide safe anchorage for ships and boats. They are formed by geographical features such as mountains, islands, or peninsulas that protect the water from strong winds and waves. This makes them ideal locations for ports and maritime activities. These harbors often have deep waters, allowing large vessels to dock without the risk of running aground. Many major cities, like San Francisco and Sydney, are built around natural harbors, benefiting from their strategic locations for trade and transportation. Natural harbors play a crucial role in global commerce and naval operations.
