(QUESTION
ANSWERS)
__________________________________________________________________________
NCERT EXERCISE
1.
Answer the following questions briefly.
(a)
What is the angle of inclination of the earth’s axis with its orbital plane?
(b)
Define rotation and revolution.
(c)
What is a leap year?
(d)
Differentiate between the Summer and Winter Solstice.
(e)
What is an equinox?
(f)
Why does the Southern Hemisphere experience Winter and Summer Solstice at
different times than that of the Northern Hemisphere?
(g)
Why do the poles experience about six months day and six months night?
Answer 1.
(a) The angle
of inclination of the earth’s axis with its orbital plane is 66½°.
(b) The
movement of the earth on its axis is called rotation. The movement of the earth
around the sun in a fixed path or an orbit is called Revolution.
(c) Every
fourth year, February has 29 days instead of 28 days. Such a year with 366 days
is called a leap year.
(d) Summer
Solstice– When the Southern hemisphere experiences the winter season and it
is summer in the northern hemisphere. At that point in time, the position of
the earth on 21st June is called the Summer Solstice.
Winter Solstice– When the Southern hemisphere experiences the summer season and the reverse occurs at the Northern hemisphere. At that point in time, the position of the earth on 22nd December is called the Winter Solstice.

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) The three dimensional model of the earth is called as Globe.
(c) 23½° 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:
1. The
Sun shines perpendicular between Tropic of Cancer and Tropic of Capricorn
throughout the year.
2. Perpendicular sun rays give more heat than slanting sun rays.
