## 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?

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

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

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

d) The three heat zones of the Earth are:
• Torrid Zone
• Temperate Zone
• Frigid Zone

e) All parallel circles from the equator up 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, as 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) India 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°
ii) 0°

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

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

d) The Antarctic circle is located in
i) the Northern hemisphere
ii) the Southern hemisphere
iii) the Eastern hemisphere
ii) the Southern 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
i) parallels of latitudes and merdians 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.

a) The Tropic of Capricorn is located at 23½°S.
b) The Standard Meridian of India is 82½° E (82° 30'E).
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.
