What is the land connecting North America and South America?

The land connecting North America and South America is known as the Isthmus of Panama. It is considered an isthmus due to its narrow strip of land that connects the two continents, bordered by the Caribbean Sea to the north and the Pacific Ocean to the south. The formation of the Panama Canal played a crucial role in establishing the isthmus as the main route of transportation between the two continents, allowing ships to bypass the lengthy journey around the tip of South America.
