Why there are no latitudes higher than 90N and 90S?

Question

Why there are no latitudes higher than 90N and 90S?

Answer 1

The earth's surface can be represented by the circumference of a circle.  The earth's poles are seperated by 180 degrees on that circle and the equator is halfway between the poles.  Latitudes are measured with respect to the equator and you end up 90 degrees in both the north and south directions.

Answer 2

If you want to see moon in mid sky, you lift head and gaze vertically up (that is 90). But at that instance, if you need to see the top of a skyscraper behind you, do you bend head still backward to see it; or turn around and see it straight?

We have adapted geometry for lat/long and so follow rules of geometry. Now, don't ask  'WHAT ARE THOSE?' If you want, go read a book about it.

Answer 3

You can't have latitudes higher than 90°. Those are the poles, of which the latitudes, or circles, resemble points. Looking directly above or below the globe, each latitude resembles a circle around the axis, with the Equator at 0° representing the largest circle around the globe.

Answer 4

because it is a 90 degree angle between the equator and the poles; you can't get any further than the poles

Answer 5

Our globe consists of 360 * from any point, but is officially  measured 90*  from the equator to the North Pole, likewise, so is there is  90* ticked off south.  

Similarly, in the Eastern hemisphere, 0* south from the equator where it descends to 90* at the South Pole.and ditto North.  (Since these latitudinals extend around the globe, ANOTHER 180* of the globe is delienated for the Eastern Hemisphere,)

The latitudinal lines encompass the entire globe and marked off as latitudinal lines frowing up from the South Pole and down from the North Pole over both hemispheres.

  

To simplify, you can think that the globe is 180* of the western circle and joins the eastern 180* at  the N.. Pole and then completes the 360* by circling the eastern hemisphere.



The longitudinal coordinates also use 0* as the equator, and fan out on a horizontal plane exactly as do the latitudes do vertically.  Hope  this helps.,
