Detailed explanation-1: -One of the most famous examples of the isthmus landform is the Isthmus of Panama. The Panama isthmus is a narrow strip of land that connects Costa Rica and Colombia. Essentially, the Isthmus of Panama connects North and South America. It is bordered by the Caribbean Sea and the Pacific Ocean.

Detailed explanation-2: -An isthmus is a narrow strip of land that connects two larger landmasses and separates two bodies of water. This type of isthmus is called a tombolo, and is formed as waves and tides slowly build up a sand bar to create a permanent link between a coastal island (called a tied island) and the mainland.

Detailed explanation-3: -Over time, massive amounts of sediment from North and South America filled the gaps between the newly forming islands. Over millions of years, the sediment deposits added to the islands until the gap was completely filled. By no later than 4.5 million years ago, an isthmus had formed between North and South America.

Detailed explanation-4: -This opens in a new window. As dates in geologic history go, the formation of the slender land bridge that joins South America and North America is a red-letter one.
