(2) Many [✓]
(3) Two [ ]
(B) Observe a globe and examine the following statements. Correct the wrong ones:
(1) Parallels of latitude lie parallel to the Prime Meridian,
Ans: Wrong:- Parallels of latitude lie parallel to the equator.
(2) All parallels of latitude converge at the equator.
Ans: Wrong:- All meridians of longitude converge at the poles.
(3) Parallels and meridians are imaginary lines.
Ans: Right.
(4) 8° 4′ 65″ N is a north meridian.
Ans: Wrong:- 8° 4′ 65″ N is a north parallel.
(5) Meridians are parallel to each other.
Ans: Wrong:- Latitudes are parallel to each other.
(C) Find the correct graticule out of the following and put a tick mark against it.
Ans: Figure (a) is correct.
(D) Answer the following:
(1) How will you express the latitude and longitude of the North Pole?
Ans: The latitude of the North Pole would be 90°N. All the meridians of longitudes pass through the North Pole. So the North pole would be 0° longitude.
(2) How much is the angular distance between the Tropic of Cancer and Tropic of Capricorn?
Ans: The angular distance between the tropic of Cancer and tropic of Capricorn is 47°.
(3) Using a globe, write down the names of the countries through which the equator passes.
Ans: The Ecuador, Colombia, Brazil, Sao tome and Principe, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, Somalia, Maldives, Indonesia and Kiribati are the countries through which the equator passes.
(4) Write down the main uses of the graticule.
Ans: (1) Graticules help us to determine the locations on the earth.
(2) In the modern age, Geographical Information Systems, Global Positioning System, Google Maps, Wikimapia, Bhuvan of ISRO also make use of graticules.
(E) Complete the following table:
