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 classified as either "land" or "ocean"), the two hemispheres do not overlap. Determinations of the hemispheres vary slightly.
Alternative hemisphere schemes can divide the planet in a way that maximizes the prominence of one geographic feature or another in each division, such as the land-water division: Land Hemisphere: Centered near 47°N, 1°E, near the city of Nantes, France, this hemisphere contains the largest possible area of land, including most of the world's ...
The Southern Hemisphere from above the South Pole. The Southern Hemisphere is highlighted in yellow. The hemispheres appear to be unequal in this image because Antarctica is not shown. The Southern Hemisphere is the half (hemisphere) of Earth that is south of the Equator. It contains all or parts of five continents [1] (the whole of Antarctica ...
Marginal seas. v. t. e. The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Australia in the west and the Americas in the east.
Most water in Earth's atmosphere and crust comes from saline seawater, while fresh water accounts for nearly 1% of the total. The vast bulk of the water on Earth is saline or salt water, with an average salinity of 35‰ (or 3.5%, roughly equivalent to 34 grams of salts in 1 kg of seawater), though this varies slightly according to the amount of runoff received from surrounding land.
This is a list of seas of the World Ocean, including marginal seas, areas of water, various gulfs, bights, bays, and straits. [2] In many cases it is a matter of tradition for a body of water to be named a sea or a bay, etc., therefore all these types are listed here.
Northern hemisphere glaciation during the last ice ages. The setup of 3 to 4 kilometer thick ice sheets caused a sea level lowering of about 120 m. The Arctic is a region around the North Pole (90° latitude). Its climate is characterized by cold winters and cool summers. Precipitation mostly comes in the form of snow.
An annotated relief map. New Zealand is located in the South Pacific Ocean at , near the centre of the water hemisphere. [4] It is a long and narrow country, extending 1,600 kilometres (990 mi) along its north-north-east axis with a maximum width of 400 kilometres (250 mi). [5]
