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

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 when it is 12.00 noon in London?
Answers:
(a) The true shape of the Earth is geoid-earth like shape. In other words, it is orange shaped.
(b) Globe. Globe is the three dimensional model of the earth.
(c) 2312° N.
(d) (i) Torrid Zone
(ii) Temperate Zone
(iii) Frigid Zone.
(e) Parallels of Latitudes and Meridians of Longitudes:
Parallels of Latitudes:
All the parallel circles from the equator to the poles are called parallels of latitudes.
Meridians of Longitudes:
All the semi-circles which join north pole to south pole are termed as meridians of longitudes.
(f) Torrid Zone receives the maximum amount of heat because of the following reasons:

The Sun shines perpendicular between Tropic of Cancer and Tropic of Capricorn throughout the year.
Perpendicular sun rays give more heat than slanting sun rays.

(g) It is 5.30 p.m. in India when it is 12.00 noon in London because of the following reasons:

London is located at 0° longitude while the time of 8212° E longitude is taken as standard time in India.
There is a difference of 8212 between the longitude of London and the Standard Meridian of India (8212 E).
Time in India is ahead of London. It is 4 minutes ahead at every longitude towards east.
Hence time in India is ahead of London by 5.30 hours (4 x 8212 = 330 minutes or 5.30 hours).

2. Tick the correct answer:

(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

Answers: (a)—(ii), (b)-(i),(c)-(i), (d)-(ii), (e)-(i).

Remark: Actually the number of longitudes is infinite. We can draw longitudes of any degree value. We show in diagrams distinct longitudes just for our convenience, e.g. the number of longitudes can be 360 (shown at gap of 1 degree), 180 (shown at every 2 degrees), and so on—as we wish.

Globe Latitudes and Longitudes Class 6 Geography Chapter 2 Very Short Answer Type Questions

Answer: Globe is a true model of the earth. It shows the earth in a small form.

2. What are the advantages of the globe? [V. Imp.]
Answer: The globe is small in shape, is convenient to carry and use, and depicts all features of the earth.

3. What are the two types of lines needed to locate any point on the earth’s surface? [V. Imp.]
Answer: Latitudes and longitudes are required to locate any point on the earth’s surface.

4. Define latitude.
Answer: One of the imaginary circles parallel to the Equator is called latitude.

5. Define longitude.
Answer: One of the imaginary circles parallel to the Prime Meridian is called longitude.

6. Which place is used as a standard for a time all over the world?
Answer: Greenwich in Britain is used as a standard for a time all over the world.

Class 6 Geography Chapter 2 NCERT Solutions Short Answer Type Questions

1. A cricket match begins at 10.30 am on January 10 in New Zealand (time zone of +12). TeU. the time in Greenwich when it is shown live on TV there.
Answer: New Zealand lies in time zone +12, Le. it is 12 hours ahead of Greenwich, or Greenwich is 12 hours behind New Zealand. So when it is 10.30 am on January 10 in New Zealand, it is 10.30 pm on January 9. So the cricket match will be telecast from 10.30 pm on Jan 9 in Greenwich.

2. Why do we have the concept of time zone? [V. Imp.]
Answer: The sun does not shine with the same intensity over all parts of the world at a particular time. If it is overhead at one place (midday), then it does not shine at all (midnight) at the place directly opposite to that place on the earth. So if we have the same time, then 12 noon will mean midday at one place, and midnight at another. To avoid such an awkward system, we have the system of time zones, so that everywhere a particular time means the same stage of the day.

3. Write a short note on Heat Zones. [Imp.]
Answer: Heat zones are the different zones of the earth, where the sun’s rays fall differently, thus causing different climate patterns. These zones are called the Torrid Zone, the two Temperate Zones, and the two Frigid Zones. The Torrid Zone is very hot since the sun shines overhead here. The Temperate Zones maintain a moderate climate, and the Frigid Zones are extremely cold.

5.How do latitudes and longitudes help in locating a point? Why is only one of them insufficient in doing this?[V. Imp.]
Answer: Latitudes and longitudes form a grid. Two different points may lie on the same latitude or the same longitude. But there exists only one point where latitude and longitude intersect. So a point can be identified with the help of the latitude and longitude on which it lies.
