Question

the latitudinal and longitudinal extent of iindia is 30 degrees but north -south extent is bigger tan east -west extent .Explain!!

Answer 1

The latitudinal and longitudinal extent of India is approximately the same i.e. 30o. The Andaman and Nicobar Islands extend further southwards and add to the latitudinal extent of India. The latitudinal extent of India from Kashmir in the north to Kanyakumari in the south is 3,214 km. India's longitudinal extent from the Rann of Kutch in the west to Arunachal Pradesh in the east is 2,933 km.

If we look at maths point of view,  the radius of earth along the lattitude and along the longitude could be different as earth's surface is not exactly spherical. radius along lattitude could probably be bigger? not sure.

Answer 2

If you have noticed in a map that the latitudes are till 90 degree while the longitudes are till 180 degree.this means that one latitide is larger as compared to one longitude.this is why the north south extend more than the east west.
