Because the cordinate system is set up to provide a unique reference to every point on the planet.
Three coordinates suffice to define a location in space. On a surface only two coordinates are required.
None, only the earths core is more closer, the moons surface is 37.000 Vertices from earth
Well this is my thought depending on where the point of dilation is the coordinates of the give plane is determined. The point of dilation not only is main factor that positions the coordinates, but the scale factor has a huge impact on the placement of the coordinates.

A point is a zero-dimensional object. It has no length, width, height, etc. Coordinates are the numerical location of that point. Point A can be at the coordinates (2,3) on a Cartesian grid.

Given only the coordinates of that point, one can infer that the point is located 10 units to the right of the y-axis and 40 units above the x-axis, on the familiar 2-dimensional Cartesian space.
A set of two coordinates defines a single point. There is only one point that has boththis latitude and this longitude.The point is in Iceland, about 80 miles northeast of Reykjavik.
71.13% of the earth is covered by water. Only 3% of that water is fresh water, the rest is salt water.
Sedimentary rocks are the type of rocks that can only form on or very near Earth's surface. Sedimentary rocks form from weathering processes that occur on Earth's surface.
Some of them but not all. For example, uniqueness. The rectangular coordinates (x, y) represent a different point if either x or y is changed. This is also true for polar coordinate (r, a) but only if r > 0. For r = 0 the coordinates represent the same point, whatever a is. Thus (x, y) has a 1-to-1 mapping onto the plane but the polar coordinates don't.
