Detailed explanation-1: -The type of isthmus built up with sand connecting to land masses is called a tombolo. Isthmus of Panama showing landform connecting two larger landmasses.
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: -Little by little, over millions of years, the sediment deposits added to the islands until the gaps were completely filled. By about 3 million years ago, an isthmus had formed between North and South America. (An “isthmus” is a narrow strip of land, with water on either side, that connects two larger bodies of land.)
