The Short Answer:
High and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
If a country is isolated, it will have to produce everything that it needs: especially food clothes and medicine. It won't be able to specialize, but it will have to focus on satisfying the needs of the people.
If it is not isolated, it can specialize in the things that it can produce the best and fastest, and hope to exchange it for the things that it can't produce.
There are two potential alternative locations for another canal across the isthmus. These are in <u>Mexico</u> and <u>Nicaragua</u>?
An isthmus is a slim strip of land that connects two larger landmasses and separates two bodies of water. This form of the isthmus is called a tombolo and is shaped as waves and tides slowly building up a sand bar to create an everlasting hyperlink between a coastal island (known as a tied island) and the mainland.
Definitely, the 2 most famous isthmuses are the Isthmus of Panama, connecting North and South America, and the Isthmus of Suez, connecting Africa and Asia.
An isthmus is a slim piece of land connecting two large regions across an expanse of water by which they may be otherwise separated. A tombolo is an isthmus that consists of a spit or bar, and a strait is the ocean counterpart of an isthmus.
