I. Answer the following questions briefly
Q 1. What is the true shape of the Earth?
Answer: The true shape of the Earth is Geoid. It is slightly flattened at the top and bottom and slightly bulging in the middle.
Q 2. What is a globe?
Answer: A globe is a small, miniature, three dimensional model of earth.
Q 3. What is the latitudinal value of the Tropic of Cancer?
Answer: The latitudinal value of Tropic of Cancer is 23½° N.
Q 4. What are the three heat zones of the Earth?
Answer: The three heat zones of the Earth are,
- Torrid zone
- Temperate zone
- Frigid zone
Q 5. What are parallels of latitude and meridians of longitude?
Answer: All parallel circles from the equator up to poles are called parallels of latitude. The lines of reference running from North pole to South pole are called meridians of longitude.
Q 6. Why does the Torrid Zone receive maximum amount of heat?
Answer: At Torrid Zone, the mid-day sun is exactly overhead at least once a year on all latitudes in between the Tropic of Cancer and the Tropic of Capricorn. Therefore this area receives the maximum heat.
Q 7. Why is it 5.30 p.m. in India and 12.00 noon in London?
Answer: It is 5.30 p.m. in India and 12.00 noon in London because the time difference between India and London is five and a half hours. As India is located east of Greenwich at 82° 30’ E, it is 5 hours 30 minutes ahead of GMT.
