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 Nantes, France). The center of the water hemisphere is the antipodal point of the center of the land hemisphere, and is therefore located at , near New Zealand's Bounty Islands in the Pacific Ocean.(in the city of
Distribution of continentsEdit
The Land Hemisphere has the substantial majority of the planet's land, including Europe, Africa, North America, nearly all of Asia and most of South America. However, even in the Land Hemisphere, the ocean area still slightly exceeds the land area. The Land hemisphere is almost identical to the hemisphere containing the greatest human population.
The Water Hemisphere has only about one-eighth of the world's land, including Australia, New Zealand, Hawaii, the Maritime Southeast Asia, and the Southern Cone of the Americas. Antarctica is solely within the water hemisphere, though sources differ as to whether it is considered land for the purposes of calculation.
The table below follows the assignments of Alphonse Berget of land to the two hemispheres.
