NCERT Solutions for class 6 Geography chapter 2 – Globe: Latitudes and Longitudes

Back Exercise

1. Answer the following questions briefly.

(a) What is the true shape of the earth?

(b) What is a 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 the parallels of latitude and meridians of longitude?

(f) Why does the torrid zone receive a maximum amount of heat?

(g) Why is it 5.30 p.m. in India and 12.00 noon in London?

Answer 1.

(a) The earth is not a perfect sphere. It is slightly flattened at the North and the South Poles and bulge in the middle.

(b) Globe is a miniature form of the Earth.

(d) The three heat zones of the Earth are:

Torrid Zone
Temperate Zone
Frigid Zone

(e) All parallel circles from the equator to the poles are called parallels of latitudes. The lines of reference running from the North Pole to the South Pole are called meridians of longitude.

(f) The torrid zone receives the maximum amount of heat, because it is present between the Tropic of Cancer and the Tropic of Capricorn. The sun is exactly over the head once a year, on all the latitudes between these two tropics.

(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 time of 82 $\frac { 1 }{ 2 }$ ° E longitude is taken as standard time in India.
There is a difference of 82 $\frac { 1 }{ 2 }$ between the longitude of London and the Standard Meridian of India (82 $\frac { 1 }{ 2 }$ 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 82 $\frac { 1 }{ 2 }$ = 330 minutes or 5.30 hours).

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 longitude

(ii) the Tropic of Cancer and the Tropic of Capricorn

(iii) the North Pole and the South Pole

Answer 2.

(ii) 0°
(i) the Poles
(ii) 180
(ii) the Southern hemisphere
(i) parallels of latitudes and meridians of longitude

3. Fill in the blanks.

(a) The Tropic of Capricorn is located at _________________.

(b) The Standard Meridian of India is ____________________.

(c) The 0° Meridian is also known as ____________________.

(d) The distance between the longitudes decreases towards___________.

(e) The Arctic Circle is located in the ____________ hemisphere.

Answer 3.

(a) The Tropic of Capricorn is located at 23½° S.

(b) The Standard Meridian of India is 82½° E Longitude.

(d) The distance between the longitudes decreases towards the poles.

(e) The Arctic Circle is located in the northern hemisphere.

In-Text 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:

First we have to know the latitude and longitude of that place.
Now we draw the meridian and parallel of latitude of that place on the basis of its longitude and latitude.
The point where these 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,

There is only one Torrid Zone lying between Tropic of Cancer and Tropic of Capricorn.
There are two Temperate Zones.
- North Temperate Zone lies between Tropic of Cancer and Arctic Circle in the Northern hemisphere.
- South Temperate Zone lies between Tropic of Capricorn and Antarctic Circle in the Southern hemisphere.

Question 4.
Do all longitudes meet at same place?
Solution:
Yes, all the longitudes meet at North Pole and 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 82 $\frac { 1 }{ 2 }$ E longitude = 82 $\frac { 1 }{ 2 }$ °
- Time in the East is ahead by 4 minutes on passing every meridian
- Hence time ahead 82 $\frac { 1 }{ 2 }$ x 4 = 330 minutes or 5.30 hours.
