GLOBE: LATITUDES AND LONGITUDES
1: Answer the following questions briefly.
Question a:– What is the true shape of the Earth?
Answer:- Earth is not a sphere it is slightly flattened at the north and south pole and bulge in the middle.
Question b:– What is a globe?
Answer:- Globe is a true model (Miniature form) of Earth. The globe is not fixed. It can be rotated the same way as a topspin or a potter’s wheel is rotated. On the globe countries and continents and oceans are shown in their correct size
Question c:– What is the latitudinal value of the Tropic of Cancer?
Answer:- The latitudinal value of tropic of cancer is 23 1/2° North in the Northern Hemisphere.
Question d:– What are the three heat zones of the Earth?
Answer:- There are three types of heat zones in the Earth they are, Torrid Zone Temperature zone, Frigid zone.
Question e:- What are the parallels of latitude and meridians of longitudes?
Answer:– All parallel circles from the equator up to the poles are called parallels of latitudes. The lines of reference running from the north pole are called meridians of longitudes.
Question f:– Why does the Torrid Zone receive the maximum amount of heat?
Answer:- The area between tropic of cancer and tropic of Capricorn The midday sun is exactly overhead at least once in a year on all latitudes in this area receives the maximum amount of heat
Question g:- Why is it 5.30 P.M. in India and 12.00 noon in London?
Answer:- In India, the longitude of 821/2° E (82° 30E) is treated as the standard meridian. The local time at this meridian. The local time at this meridian is taken as the standard meridian for the whole country. It is known as the Indian Standard Time (IST) India located east of Greenwich at 82° 30E in 5 hours and 30 minutes ahead of GMT so it will be 5:30 in India when it is 2 noon in London
