Coordinates in the northern and western hemispheres would have positive latitude and negative longitude. For example, a coordinate like 40°N, 100°W falls in the northern and western hemispheres.
There has been a tremendous historical significance to the hemispheres. The eastern hemisphere is the Old World from whence came the European colonists to the western hemisphere or New World (even the aboriginal people also came to the western hemisphere from the eastern hemisphere, they just did it some 30,000 years earlier than the Europeans). The vast Altantic and Pacific oceans make a natural geographic division of the world into east and west hemispheres, since north and south America are set apart by the oceans. The other hemispheric division of the world into north and south hemispheres also serves a purpose, since seasons are experienced differently depending upon whether you are in the north or the south hemisphere. Winter in the north hemisphere is summer in the south hemisphere, and summer in the north is winter in the south, so this is a meaningful distinction.
El Salvador is in the southern hemisphere because it is south of the equator. That is how the northern and southern hemispheres are set. Any place north of the equator is in the northern hemisphere. Any place south of the equator is in the southern hemisphere.
Both differentiations are often made, but the world is sometimes arbitrarily divided between the Eastern and Western hemispheres as a mark between the "New World" (the Americas, perceived as a vast new land to colonize and expand into by European and a few Asian kingdoms) and the "Old World." This is also where we get the geographic regional names "Middle East" and "Far East." The dividing line is the Prime Meridian, or zero degrees longitude, which runs through Greenich, England; most (but not all) of Europe and Africa lies to the east of this line. The "far boundary" is at 180 degrees longitude, roughly where the International Date Line is. Extreme eastern Russia does cross 180 degrees longitude and is technically in the Western Hemisphere, though the International Date Line was drawn in the Bering Straight between Asia and North America (and Russia and the United States) to keep it on the same day with the majority of Asia. Crossing the International Date Line boundary, going eastward, one must set one's calendar back by a day.
There are many imaginary lines circling the Earth. The Equator is one of them that circles the Earth round the middle, the Tropics of Cancer and Capricorn are further north and south and the Arctic and Antarctic circles further north and south again.yea
An escarpment is a steep slope or long cliff that separates two level surfaces of differing elevations. The Great Plains are part of the western region that is set apart by the Rocky Mountains escarpment, which marks the transition from the Rocky Mountains to the flat plains.
That depends on which set of hemispheres you are talking about. Both Paris, France, and Miami, Florida are north of the Equator, putting both in the Northern Hemisphere. However, a much more artificial set of hemispheres is "East" and "West" defined by the Prime Meridian. As this is a throwback to British Imperialism that line is drawn to make England the center of the world, with the New World to the west, and most of France, including Paris, to the east. So, long story short, both are in the Northern Hemisphere, however Miami is in the Western Hemisphere while Paris is in the East Hemisphere.
The name given to a set of coordinates is "coordinate system".
The northern and southern Hemispheres each comprise 90 degrees of latitude. On your map or globe, you're free to draw as few or as many lines as you'd like to see in that range. There is no standard set of 'lines'.
It's a set of geographic coordinates. These coordinates describe a point in the Pacific Ocean, almost exactly 1,000 miles due west of Shelter Cove, on the northern coast of California.

The set of all the x-coordinate is called The Range. * * * * * Though more often, the x-coordinates are called the DOMAIN (and the y-coordinates are the RANGE).

Interpolation in general is a way to determine intermediate values from a set of coordinates. Linear interpolation would be to fit a single linear function to the entire set of coordinates. Piecewise linear interpolation would then be to determine intermediate values from the set of coordinates by fitting linear functions between each set of coordinates. Connect-the-dots so to speak.
