What are different kinds of isthmus?

There are several types of isthmuses, each characterized by its unique geographical features:

- Land Isthmus: A land isthmus is a narrow strip of land connecting two larger landmasses or separating two bodies of water. For example, the Isthmus of Panama connects North and South America, while the Isthmus of Suez connects Africa and Asia.

- Sea Isthmus: A sea isthmus occurs when a narrow strip of sea separates two larger bodies of land. The Isthmus of Corinth in Greece is an example of a sea isthmus, where the narrow Gulf of Corinth separates the Peloponnese peninsula from mainland Greece.

- Lake Isthmus: A lake isthmus is a narrow land bridge or strip of land that separates two parts of a lake. The Isthmus of Ometepe is an example of a lake isthmus, connecting the two volcanic islands of Ometepe in Lake Nicaragua.

- River Isthmus: A river isthmus is a narrow strip of land that separates two parts of a river. The Isthmus of Bratislava in Slovakia is an example of a river isthmus, where the Danube River splits into two branches around a small island.

- Canal Isthmus: A canal isthmus refers to a narrow strip of land that has been cut through to create a canal. The Panama Canal, which connects the Atlantic and Pacific Oceans, is a notable example of a canal isthmus.
