Answers
The earth revolves around its axis and the sun completes a revolution once every twenty four hours.
The earth is divided into 360 degrees of imaginary lines called longitudes lining vertically between the poles which the sun crosses while completing its revolution.
360 degrees of longitudinal lines divided by twenty four hours is four minutes per longitude.
The sun is positioned at 360 degrees at 24 hours, 15 degrees at 1 hour and 1 degree per four minutes.
The time difference between each longitude is four minutes.
The difference between the two longitudes that are adjacent is 4 minutes.
Each longitude is called a degree.
The earth is divided longitudinally into 360 such longitudes, all of which are imaginary.
They run vertically along the surface of the earth from north to south pole and divide the world into time zones.
