Question 17:
India lies entirely in the Northern Hemisphere. Justify this statement with reference to its latitudinal and longitudinal extent, and explain how this geographical position influences India's climate.
Answer:

India is located entirely in the Northern Hemisphere because its mainland extends between 8°4'N to 37°6'N latitude and 68°7'E to 97°25'E longitude. Since all latitudes are north of the Equator (0°), India lies completely in the Northern Hemisphere.

This position influences India's climate in the following ways:

  • The Tropic of Cancer (23.5°N) passes through the middle of India, dividing it into tropical and subtropical zones.
  • The northern location results in distinct seasons: winter, summer, monsoon, and post-monsoon.
  • The Himalayas block cold winds from Central Asia, giving India a relatively warmer climate compared to other regions at similar latitudes.
