Which of the following is NOT the reason for limited air services between 10°-35° latitudes in the Southern hemisphere?
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → Efficient railway network is available
Option (1) Limited landmass — A reason (Incorrect). Between 10° and 35° south most of the belt is ocean. With little land, there are few places to fly between, so few air routes are set up.
Option (2) Lack of economic development — A reason (Incorrect). Air travel is costly. Where economic development is low, few people and firms can pay for it, so low demand keeps air services few.
Option (3) Sparser population distribution — A reason (Incorrect). Few people means few passengers, and a regular air service does not pay without them, so fewer flights are run.
Option (4) Efficient railway network is available — Not a reason (Correct). Air services here are held back by few people, little land and low development; a railway network is not what limits them.
NCERT (2025-26): “Inter-Continental Air Routes In the Northern Hemisphere, there is a distinct east-west belt of inter-continental air routes. Dense network exists in Eastern U.S.A., Western Europe and Southeast Asia. U.S.A. alone accounts for 60 per cent of the airways of the world. New York, London, Paris, Amsterdam, Frankfurt Rome, Moscow, Karachi, New Delhi, Mumbai, Bangkok, Singapore, Tokyo, San Francisco, Los Angeles and Chicago are the nodal points where air routes converge or radiate to all continents. Africa, Asiatic part of Russia and South America lack air services. There are limited air services between 10-35 latitudes in the Southern hemisphere due to sparser population, limited landmass and economic development.” |
