- Latitudes and Longitudes
Q1. Fill in the blanks.
The Frigid Zone lies near the Poles.
The Antarctic Circle is located in the southern
The Standard Meridian of India is
82½ degree east.
The 0° Meridian is also known as Prime
The southern half is known as the Southern
Tropic of Capricorn in the Southern
The distance between the longitudes
decreases towards the poles. True
The Arctic Circle is located in the southern
The northern half of the earth is known as the
Southern Hemisphere. False
90 degrees north latitude marks the North Pole
and 90 degrees south latitude marks the South Pole. True
Q3. How many
lines of longitude are there in total?
Q4. How many latitudes are
there in total?
Q5. What is the value of the prime meridian?
value of the prime meridian is zero degree.
Q6. What is
the latitudinal value of the Tropic of Cancer?
Ans. The latitudinal value
of the Tropic of Cancer is 23½ degrees north.
Q7. What is a grid?
is a network of parallels of latitudes and meridians of longitudes.
Q8. What are the three heat
zones of the Earth?
The three heat zones of the Earth are Torrid Zone, Temperate Zones and Frigid Zones.
Q9. What is the true shape of the earth?
is not a sphere. It is slightly flattened at the North and the South Poles and
bulge in the middle.
Q10. What is prime meridian?
which passes through Greenwich, where the British Royal Observatory is located
is called the Prime Meridian.
Q11. What do you mean by the term equator?
imaginary line running on the globe divides it into two equal parts. This line
is known as the equator.
Q12. What is a globe?
is a true model (miniature form) of the earth. On the globe, countries,
continents and oceans are shown in their correct size.
Q13. Why is it 5.30 p.m. in India and 12.00 noon in London?
located east of Greenwich at 82°30'E is 5 hours and 30 minutes ahead of GMT. So
it will be 5:30 p.m. in India when it is 12:00 noon in London.
Q14. Why does the Torrid Zone
receive maximum amount of heat?
The mid-day sun is exactly overhead at least once a year on all latitudes in between
the Tropic of Cancer and the Tropic of Capricorn. This area, therefore, receives
the maximum heat and is called the Torrid Zone.
Q15. Which longitude is treated as the standard meridian for
India, the longitude of 82.50° E (82° 30'E) is treated as the standard meridian.
The local time at this meridian is taken as the standard time for the whole
country. It is known as the Indian Standard Time (IST).
Q16. Which heat zone do these places lie in?
10 degree north, 25 degree south and 89 degree south
degree north – Torrid Zone
degree south – South Temperate Zone
degree south – Frigid Zone
