What is the nature of the length of the latitudinal circle as we move ...
  • The length of the lines of latitude decreases as we move towards the poles.
  • The total number of latitudes is 181.
  • The distance between two latitudes is about 111 km.
  • The distance between two latitudes is called a 'zone'.
IMPORTANT FACTS-:
Latitude Line-:
  • The angular distance from the equator of a place on the globe to the center of the earth towards north or south is called the latitude of that place.
  • Here the angular distance is related to the angle formed at the center of the earth from the equator.
  • If a place is north of the equator then its latitude will be north and if it is south then its latitude will be south.                                                
  • In the figure there is a place A on the earth, whose angle from the equator to the center of the earth is 45 degrees. 
  • So the latitude of this place will be 45 degrees. 
  • The total number of lines of latitude is 90 (south) + 90 north + equator = 181 latitudes.
  • The total number of longitude lines is 360.
  • The distance between two lines of longitude is 111.3 km. On moving towards the poles, the distance between the lines of longitude decreases. And the distance between them at the poles is 0 km.
GEOGRAPHICAL ASPECTS-:
Time offset-:
  • When there is a difference of one longitude, there is a difference of 4 minutes in time.
  • Since the earth rotates from west to east.
  • As a result, on moving east, time increases by 4 minutes at each longitude and on moving west, time decreases by 4 minutes at each longitude.
