Globe : Latitudes and Longitudes : Lesson 2 NCERT Class VI (6th) Social Science Geography Exercises

 Questions and Answers

1. Question : Answer the following question briefly :-

(a) What is the true shape of the Earth ?
Answer : The Earth look like an orange, bulging on the side and slightly flat at the top and bottom. The true shape of the Earth is a geoid.

 (b) What is a globe ?
Answer : A globe is a three-dimensional representation of the Earth.

(c) What is the latitudinal value of the the Tropic of Cancer?

Answer : It is 23 1/2 degree North.

(d) What are the three heat zones of the Earth ?
Answer : The three heat zones of the Earth are torrid zones, temperate zone and frigid zone.

(e) What are parallel of latitude and meridian of  longitude?
Answer: All parallel circle from the equator up to the poles are called parallels of latitude . Meridians of longitudes are the lines running from north pole to the south poles.

(f) Why does the torrid zone receive maximum amount of heat ?
Answer : The torrid zone  is the area that receive maximum heat of the Sun because the mid day Sun is exactly overhead at least once in a year on all latitude in between the Tropic of Cancer and the Tropic of Capricorn.

(g) Why is 5.30 p.m. in India and 12:00 noon in Londen ?
The time difference between India and London is 5 and a half hours. India is located east of the Greenwich at 82 degree 30 E. So, it will be 5:30 pm in India when it is 12 noon in London. 
The time difference between each degree of longitude is 4 minute and since India is in the east, the time here will be ahead of the Greenwich time.
