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 remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is somewhat humid and covered by vegetation, while large sheets of ice at Earth's polar deserts retain more water than Earth's groundwater, lakes, rivers and atmospheric water combined.
Southern Hemisphere climates tend to be slightly milder than those at similar latitudes in the Northern Hemisphere, except in the Antarctic which is colder than the Arctic. This is because the Southern Hemisphere has significantly more ocean and much less land; water heats up and cools down more slowly than land. [3]
Its surface is 60.7% water, compared with 80.9% water in the case of the Southern Hemisphere, and it contains 67.3% of Earth's land. [3] The continents of North America and mainland Eurasia are located entirely in the Northern Hemisphere, together with about two-thirds of Africa and a small part of South America.
The Western Hemisphere is the half of the planet Earth that lies west of the Prime Meridian —which crosses Greenwich, London, England —and east of the 180th meridian. [1][2] The other half is called the Eastern Hemisphere. Geo-politically, the term Western Hemisphere is often used as a metonym for the Americas or the "New World", even ...
List of countries and dependencies by area. Dymaxion map of the world with the 30 largest countries and territories by area. This is a list of the world's countries and their dependencies by land, water, and total area, ranked by total area. The entries in this list include, but are not limited to, those in the ISO 3166-1 standard, which ...
Water has a very high specific heat capacity, meaning it takes a lot more to warm it up than air or land. On the flip side, water also retains heat longer, leading to a much more gradual drop off ...
