The Gibraltar Strait is a narrow waterway that connects the Atlantic Ocean to the Mediterranean Sea. It is located between the southern tip of Spain and the northern coast of Morocco, making it a crucial passage for maritime traffic. The strait is approximately 13 kilometers (8 miles) wide at its narrowest point. This strait is historically significant as it has served as a strategic military and trade route for centuries. The Rock of Gibraltar, a prominent limestone promontory, stands at the northern entrance of the strait and is a well-known landmark. The area is also rich in biodiversity, supporting various marine life.
