Question

1) Why latitudes are expressed in degrees
2) why longitudes are also known as meridians
3) mention any two features of latitudes.

Answer 1

1) Latitude and longitude form a geographical coordinate system used for locating places on the surface of the earth. They are angular measurements, expressed as degrees of a circle measured from the center of the earth. The earth spins on its axis, which intersects the surface at the north and south poles. And hence they are measured in degrees.
