Chapter 2 Globe Latitudes and Longitudes

Question 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 parallels of latitude and meridians of longitude?
(f) Why does the torrid zone receive 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 sphere. It is slightly flattened at the North and South Poles and bulge in the middle.

(b) Globe is the true model of the Earth.

(c) The latitudinal value of the Tropic of Cancer is 23½ N.

(d) The three zones of the Earth are :

(i) Torrid Zone
(ii) Temperate Zone
(iii) Frigid Zone.

(e) All the parallel circles from the equator to the poles are called parallels of latitudes.

All the semi-circles which join north pole to south pole are termed as meridians of longitudes.

(f) The torrid zone receive maximum amount of heat when the mid-day Sun is exactly overhead at least once a year on all latitudes in between the Tropic of Cancer and Tropic of Capricorn.

(g) India is located east of Greenwich at 82°30′ E is 5 hours and 30 minutes ahead of GMT. So it will be 7:30 p.m. in India when it is 2:00 p.m. noon in London.

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 merdians of longitudes
(ii) the Tropic of Cancer and the Tropic of Capricorn
(iii) the North Pole and the South Pole

Answer

(a) (ii) 0°

(b) (i) the Poles

(c) (ii) 180 

(d) (ii) the Southern hemisphere

(e) (i) parallels of latitudes and meridians of longitudes

Question 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

(a) The Tropic of Capricorn is located at  23 ½ ° N

(b) The Standard Meridian of India is 80° 30´ E Longitude.

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

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

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