The Dymaxion map projection, also called the Fuller projection, is a kind of polyhedral map projection of the Earth's surface onto the unfolded net of an icosahedron. The resulting map is heavily interrupted in order to reduce shape and size distortion compared to other world maps , but the interruptions are chosen to lie in the ocean.
A landmass, or land mass, is a large region or area of land that is in one piece and not noticeably broken up by oceans. [1] [2] The term is often used to refer to lands surrounded by an ocean or sea, such as a continent or a large island. [3] [4] In the field of geology, a landmass is a defined section of continental crust extending above sea ...
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.
Pangaea, the supercontinent that existed about 200 million years ago and combined most of dry land on Earth into one giant landmass (according to the BBC), is well known.
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, ranked by total area, including land and water. This list includes entries that are not limited to those in the ISO 3166-1 standard, which covers sovereign states and dependent territories.
Antarctica provides the water hemisphere with the majority of Earth's ice. Most of the Pacific Ocean and the Indian Ocean, and the whole Southern Ocean, are in the water hemisphere. The water hemisphere is approximately 89 percent water (almost all pertaining to the World Ocean), 6 percent dry land and 5 percent polar ice cap. [1]
A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
The Schmidt net's horizontal axis can then be used as a scalar measuring device to convert the point's latitude (relative to the pole) into a radial distance from the centre of the circle. Alternatively, the Schmidt net could be replaced entirely with a correctly projected polar grid, and grid squares from a map re-drawn into this disc.
