  • India is the only country after which an ocean has been named, that is Indian Ocean. 
  • This region may gain geopolitical and geoeconomic importance in the near future, it organised on the pattern of Asia-pacific region or European Economic Community. 

Size and Shape

  • India is the seventh largest country in the world after Russia, Canada, China, USA. Brazil and Australia.
  • India commands a total geographical area of 32,87,263 square km. which is roughly 0.57 per cent of the area of the earth and 2.4 per cent of the total area of the land. This is 2.4 per cent of the total area of the land. 
  • This 2.4 per cent of the land area is occupied by 16 per cent of the world population making India second most populous country in the world. 
  • India has roughly a quadrangular shape.

  • Infact the southernmost extent goes up to 6°45' north latitude to cover the last island known as Pygmalion point or Indira point. 
  • With almost 30° of longitudinal extent the country may be divided into two zones but India has adopted only one standard meridian that is 82°30' cast longitude to determine Indian Standard Time (5 ½  hours ahead of G.M.T.). 
  • The Tropic of Cancer divides the country into two equal halves—the southern halves falling under the Torrid Zone and the northern halves forming a sub-tropical zone. 
  • India's neighbours include Pakistan and Afghanistan in the west, China, Nepal and Bhutan in the north and Bangladesh and Myanmar in the cast.
