With examples such as Panama and Suez, what is the name for a narrow strip of land connecting two larger land areas with water on each side?
Isthmus Isthmus An isthmus ( or ; plural: isthmuses; from ) is a narrow piece of land connecting two larger areas across an expanse of water by which they are otherwise separated. A tombolo is an isthmus that consists of a spit or bar, and a strait is the sea counterpart of an isthmus. Canals are often built across isthmuses, where they may be a particularly advantageous shortcut for marine transport. For example, the Panama Canal crosses the Isthmus of Panama, connecting the North Atlantic and Pacific Oceans; the Suez Canal connects the Mediterranean Sea and the Red Sea, cutting across
Land and water hemispheres Land and water hemispheres The land and water hemispheres of Earth, sometimes capitalised as the Land Hemisphere and Water Hemisphere, are the hemispheres of Earth containing the largest possible total areas of land and ocean, respectively. By definition (assuming that the entire surface can be classed as either "land" or "ocean") the two hemispheres do not overlap. Determinations of the hemispheres vary slightly. One determination places the centre of the Land Hemisphere at (in the city of Nantes, France). The center of the water hemisphere is the antipodal point of the center of the land hemisphere, and is therefore located
