NCERT Solutions for Class-6 Geography Chapter-2 Globe Latitudes and Longitudes

NCERT TEXTBOOK EXERCISES

Question 1. Answer the following questions briefly:
(a) What is the true shape of the earth?
(b) What is the globe?
(c) What is the latitudinal value of the Tropic of Cancer?
(d) What are the three heat zones of the Earth?
(e) What are parallels of latitude and meridians of longitude?
(f) Why does the torrid zone receive the maximum amount of heat?
(g) Why is it 5.30 p.m. in India and 12.00 noon in London?
Solution:
(a) The earth looks like an orange, bulging on the sides and slightly flat at the top and bottom. The true shape of the earth v a geoid.
(b) A globe is an exact miniature model of the earth. It shows the earth in its actual shape, with all continents, oceans, etc marked at their proper places.
(c) It is 23% North.
(d) The heat zones of the Earth are the Torrid Zone, the Temperate Zones, and the Frigid Zones.
(e) All parallels circles from the equator up to the poles are called parallels of Latitudes. Meridians of longitude are the lines of reference running from the North pole to the South pole.
(f) The mid-day sun directly faces the area between the Tropics of Cancer and Capricorn. So the heat received is maximum at these latitudes. These latitudes fall under the Torrid Zone.
(g) The time difference between India and London is five and a half hours. India is located east of Greenwich at 82° 30’E. So, it will be 5.30 p.m. in India when it is 12.00 noon in London. The time difference between each degree of longitude is 4 minutes and since India is in the east, the time here will be ahead of Greenwich Time.

Question 2. Tick the correct answers.
(a) The value of the prime meridian is
(i) 90°
(ii) 0°
(iii) 60°

(b) The frigid zone lies near
(i) the Poles
(ii) the Equator
(iii) the Tropic of Cancer

(c) The total number of longitudes are
(i) 360
(ii) 180
(iii) 90

(d) The Antarctic circle is located in
(i) the Northern hemisphere
(ii) the Southern hemisphere
(iii) the Eastern hemisphere

(e) Grid is a network of
(i) parallels of latitudes and meridians of longitudes
(ii) the Tropic of Cancer and the Tropic of Capricorn
(iii) the North Pole and the South Pole.
Solution:
(a) → (ii) 0°
(b) → (i) the Poles
(c) → (i) 360
(d) → (ii) the Southern hemisphere
(e) → (i) parallels of latitudes and meridians of longitudes

Question 3. Fill in the blanks:
1. The Tropic of Capricorn is located at …….
2. The Standard Meridian of India is ………
3. The 0° Meridian is also known as ……….
4. The distance between the longitudes decreases towards ……….
5. The Arctic Circle is located in the ………. hemisphere.
Solution:

1. 2312 South of equator
2. 8212° E
3. Prime Meridian or Greenwich Line
4. Poles
5. Northern

INTEXT QUESTIONS

Question 1. How to locate a place on it (the Earth/globe)?
Solution: If we want to locate a place on the globe we have to do the following exercise,
1. First, we have to know the latitude and longitude of that place.
2. Now we draw the meridian and parallel of latitude of that place on the basis of its longitude and latitude.
3. The point where this meridian and parallel of latitude intersect themselves will be the location of that place.

Question 2. In which direction does the equator run-North-South or East-West?
Solution: The Equator runs in East-West direction.

Question 3. How many Torrid and Temperate Zones are there on the Earth?
Solution: On the Earth,
1. There is only one Torrid Zone lying between Tropic of Cancer and Tropic of Capricorn.
2. There are two Temperate Zones.
    (a) North Temperate Zone lies between the Tropic of Cancer and the Arctic Circle in the Northern hemisphere.
    (b) South Temperate Zone lies between the Tropic of Capricorn and Antarctic Circle in the Southern hemisphere.

Question 4. Do all longitudes meet at the same place?
Solution: Yes, all the longitudes meet at the North Pole and the South Pole. They are semi-circles.

Question 5. Do you know what is the time difference between India and England?
Solution: The time difference between India and England is of 5.30 hours.

• If it is noon in England, it is 5.30 p.m. in India because time is ahead in India than in England by 5.30 hours.
• This can be calculated in the following manner:
  • Difference between 0° longitude and 8212 E longitude = 8212°
  • Time in the East is ahead by 4 minutes on passing every meridian
  • Hence time ahead 8212 x 4 = 330 minutes or 5.30 hours.
