What is a Coastline?

Coastline refers to the boundary between the land and the sea, where the shore meets the ocean. It includes both the beaches and cliffs along the edge of the continent, as well as any islands or other landforms that are located close to the coast. The length of a country's coastline can vary greatly depending on how it is measured, and some countries have very long coastlines due to their location on large bodies of water such as oceans or seas.

Example:
"The coastline of Australia stretches for over 25,000 kilometers, making it one of the countries with the longest coastlines in the world."

10. What is a strait ?
A strait is a narrow body of water that connects two larger bodies of water, such as oceans or seas. It allows for navigation and trade between the two bodies of water, and can also be an important route for shipping and other marine activities. Some well-known straits include the Strait of Gibraltar, which connects the Mediterranean Sea to the Atlantic Ocean, and the Bering Strait, which separates Asia and North America.

Example:
"The Strait of Hormuz is a strategic waterway that connects the Persian Gulf to the Gulf of Oman, and is a vital shipping route for oil exports."
