Geography (The Earth Our Habitat) -Class 6 – Chapter 2- Globe Latitudes and Longitudes -NCERT Exercise Solutions

1. Answer the following questions briefly.

(a) What is the true shape of the earth?
Answer The earth is not a sphere. It is slightly flattened at the North and South Poles and bulges in the middle.

(b) What is a Globe?
Answer Globe is a true miniature model of the earth where countries, continents, and oceans are shown in their correct size.

(c) What is the latitudinal value of the Tropic of Cancer?
Answer The latitudinal value of the Tropic of Cancer is 23.5° north, where the sun is directly overhead at noon on June 21.

(d) What are the three heat zones of the Earth?
Answer The three heat zones of the earth are-
(1) Torrid Zone- This zone receives the maximum heat.
(2) Temperate zones- these zones receive moderate heat.
(3) Frigid zones- these zones are very cold.

(e) What are parallels of latitude and meridians of longitude?
Answer All parallel circles from the equator up to the poles are called parallels of latitudes and The line of reference running from the North Pole to the South Pole is called Meridians of Longitude.

(f) Why does the torrid zone receive the maximum amount of heat?
Answer Because the Torrid zone lies between the Tropic of cancer and the Tropic of Capricorn where the mid-day sun is exactly overhead at least once a year on all latitudes between this zone hence this zone receives the maximum amount of heat.

(g) Why is it 5.30 p.m. in India and 12.00 noon in London?
Answer In London, the Greenwich Mean Time is followed. The Indian Standard Time is 5.30 hours ahead of Greenwich Mean Time. That is why, when it is 12 noon in London, it is 5.30 p.m. in India.
