Question 1:Which one of the following scholars coined the
term ‘Geography’?
A) Herodotus
B)Eratosthenes
C)Galileo6
D) Aristotle
Explanation:Option (b) is correct.
About Geography:
❖ The term geography was first coined by a
Greek scholar (around 300-200 BC)
Eratosthenes.
❖ The word geography has been derived
from two words of the Greek language
geo (earth) and graphos (to describe).
❖ It means the description of the earth.
❖ It is the science or study which is devoted
to the overall analysis of all features and
associated phenomena like Land, Oceans,
Atmosphere, etc..
Question 2:Consider the following statements:
1. Centrifugal force is the apparent outward
force on a mass when it is rotated.
2. The centripetal force keeps an object
moving in a circle and is always pointed
toward the centre. of that circle.
3. In the solar system, centrifugal forces are
always greater than centripetal forces.
Which of the statements given above is/are
correct?
A)1and 3 only
B) 1 and 2 only
C) 3 only
D) 1, 2, 3
Explanation:Option (b) is correct: ❖ Centripetal and centrifugal forces are the
forces experienced by rotating objects.
❖ Centrifugal force is the apparent
outward force on a mass when it is
rotated. (statement 1 is correct)
❖ The centripetal force keeps an object
moving in a circle and is always pointed
toward the centre of that circle. For
instance, the gravitational force of the sun
is a centripetal force that keeps the Earth
orbiting around it. (statement 2 is
correct)
❖ In the solar system, centrifugal and
centripetal forces are balancing each
other. (statement 3 is not correct).
Question 3:The angular distance of a point on the earth’s
surface, measured in degrees from the Centre
of the earth is known as
A) Longitude
B) Latitude
C)Greenwich line
D)International Date Line
Explanation:Option (b) is correct:
About Latitude:
❖ Latitude is the angular distance of a
point on the earth’s surface, measured in
degrees from the Centre of the earth.
These are parallel to the equator ,
therefore, called parallels of latitude.
❖ These parallels are in the form of circles
with unequal diameters to study every
zone of the earth.
❖ The largest circle is the Equator (0°
latitude) while at the poles they shrink to
a point (90° N & S).
❖ There are 181 latitudes in total..
Question 4: Which gas do plants absorb from the atmosphere?
A) Carbon dioxide
B) Oxygen
C) Nitrogen
D) Hydrogen
Explanation: Plants absorb carbon dioxide from the atmosphere.
Question 5: With reference to the earth, consider the
following statements:
1. It is the fourth nearest planet to the sun in
the solar system.
2. It is the largest planet in the solar system.
Which of the statements given above is/are
correct?
A) 1 only
B)2 only
C)1 and 2 only
D)Neither 1 nor 2
Explanation:Option (d) is correct:
About Earth:
❖ It is the third nearest planet to the sun.
(statement 1 is not correct)
❖ It is the fifth largest planet in the solar
system. (statement 2 is not correct)
❖ It is slightly flattened at the poles, which
is described as a Geoid (earth-like shape).
Question 6: Which of the following planet is also called
Blue Planet?
A)Venus
B)Mercury
C)Earth
D) Mars
Explanation: Option (c) is correct: ,
About Earth:
❖ It is the third nearest planet to the sun.
It is the fifth largest planet in the solar
system.
❖ It is slightly flattened at the poles, which
is described as a Geoid (earth-like shape).
❖ The earth is neither too hot nor too cold
and favourable conditions to support life
are found only on the earth.
❖ Its two-thirds surface is covered by
water thus it appears blue. Therefore it is
also called a blue planet.
❖ Earth rotates on its axis which is called
the axis of rotation.
❖ The Equator divides the earth into
two equal parts or halves..
