Chapter 2: Latitudes and Longitudes
Answer the following questions briefly.
a. What is the true shape of the earth?
Answer: The true shape of the Earth is not sphere. It is a bit flattened at the two poles, North and South and bulge in the middle.
b. What is a globe?
Answer: A globe is a small/miniature form of the Earth.
c. What is the latitudinal value of the Tropic of Cancer?
Answer: Tropic of Cancer is present in the Northern Hemisphere. The latitudinal value of the Tropic of Cancer is 23½° N.
d. What are the three heat zones of the Earth?
Answer: The three heat zones of the Earth are:
e. What are parallels of latitude and meridians of longitude?
Parallel of latitudes: The parallel circles starting from the equator up to the poles are called parallels of latitudes.
Meridians of longitudes: The line of references running from the North Pole to the South Pole are called meridians of longitudes.
f. Why does the torrid zone receive maximum amount of heat?
Answer: The area between the Tropic of Cancer and Tropic of Capricon is the torrid zone. The mid-day sun is exactly overhead on the latitudes lying in the Torrid zone. Thus, it receives maximum amount of heat.
g. Why is it 5.30 p.m. in India and 12.00 noon in London?
Answer: India is located at east of Greenwich at 82°30'E, which is 5 hours and 30 minutes ahead of GMT (Greenwich Mean Time). Thus, when it is 12:0 noon in London, it is 5:30 in India.
