Correct option is A
The correct answer is (a) 23.5°N.
The Tropic of Cancer (23.5°N) passes through the Rann of Kutch in Gujarat.
It marks the most northerly circle of latitude on Earth at which the sun can be directly overhead.
Its passage through India significantly influences the climate and vegetation of the regions it crosses.
Information Booster:
Tropic of Cancer (23.5°N) crosses 8 Indian states including Gujarat, making it a key climatic boundary.
Rann of Kutch is one of the largest salt marshes in the world and becomes submerged during monsoons.
The Great Rann and Little Rann are home to wildlife like the Indian Wild Ass and host the Rann Utsav cultural festival.
This region also shares an international border with Pakistan.
Additional Information (Other Key Geographical Lines):
Equator (0° latitude):
Divides the Earth into the Northern and Southern Hemispheres.
Passes through countries like Ecuador, Kenya, and Indonesia.
Regions near the Equator experience a tropical rainforest climate.
Tropic of Capricorn (23.5°S):
Southern counterpart of the Tropic of Cancer.
Passes through countries like Brazil, South Africa, and Australia.
Arctic Circle (66.5°N) & Antarctic Circle (66.5°S):
These mark the boundaries of polar day and polar night.
Regions beyond these circles experience continuous daylight or darkness during solstices.
Prime Meridian (0° longitude):
Passes through Greenwich, London.
Divides Earth into Eastern and Western Hemispheres.
Used as the reference for Greenwich Mean Time (GMT).
International Date Line (~180° longitude):
Not a straight line; it zigzags to avoid dividing countries into different days.
Crossing it changes the calendar date by one day.
