Q7: What is the true shape of the earth?
Answer: The true shape of the earth is geoid. The earth is slightly flattened at the North and South poles and bulges in the middle.
Q8: What is a globe?

Q9: What are latitudes?
Answer: Latitudes are imaginary lines drawn from west to east on the globe. These lines help us to find the location of places on the surface of the earth.
Q10: How are latitudes and longitudes drawn?
Answer: Latitudes are drawn east to west and longitudes are drawn north to south on the globe.

Q11: What is the latitudinal value of the Tropic of Cancer?
Answer: The Tropic of Cancer lies 23½° north of the Equator.
Q12: What are the three heat zones of the Earth?
Answer: The three heat zones of the earth are:
- Torrid zone,
- Temperate zone and
- Frigid zone.
Q13: What are parallels of latitude and meridians of longitude?
Answer: All parallel circles from the Equator up to the Poles are called parallels of latitudes. The lines of references running from the North Pole to the South Pole are called meridians of longitudes.
Q14: Why does the torrid zone receive maximum amount of heat?
Answer: The area between the Tropic of Cancer and the Tropic of Capricorn is known as the Torrid Zone. The mid-day Sun is exactly overhead at least once a year on all the latitudes in this area; therefore, this area receives maximum amount of heat.
Answer: An equator is an imaginary line running horizontally on the globe divides it into two equal halves.
Q16: Name the four important parallels of latitudes.
Answer: The four important parallels of latitudes are:
- Tropic of Cancer,
- Tropic of Capricorn,
- Arctic Circle and
- Antarctic Circle.
Q17: What is Prime Meridian?
Answer: The meridian which passes through Greenwich (where the British Royal observatory is located) is called Prime Meridian.
