Answer 8: True

Explanation: If one measures the angle from the Pole Star to the place where he/she is, the measured value is the latitudinal value of the place.  

Question  9. How many standard times does Russia have?

Answer 9: Russia has eleven standard times.

Question 10. What is the latitudinal value of the Antarctic Circle?

Answer 10: The latitudinal value of the Antarctic Circle is 66 ½ ° S.

Question 11. What is a globe?

Answer 11:  Globe is a miniature representation of the earth. The continents and oceans are illustrated on the globe according to their appropriate size. The globe is not fixed but can be rotated around a needle just like the earth rotates around its axis. Globes can vary in size from small to big ones.

Question  12. What is the axis?

Answer 12: The axis is an imaginary line of the earth around which it rotates from the west to the east. The axis joins the North Pole and the South Pole of the planet. It is tilted. 

Question 13. What do you mean by IST?

Answer 13: The local time of the meridian at 82 ½ °E has been taken as the official time for India. This time is called Indian Standard Time or IST. The meridian at 82 ½ °E has been chosen because it is the central meridian of the country.

Question  14. What is the Equator?

Answer 14: The Equator is an imaginary line in the middle of the earth from the west to the east. It divides the globe into two equal halves: the Northern Hemisphere and the Southern Hemisphere. The Equator bears the value of  0°  determining how north or south a place is on the earth’s surface. It helps to locate places on earth.  

Question  15. What is the true shape of the earth?

Answer 15:  The earth is not a complete sphere. It is ellipsoid in shape. That means the earth is slightly flat at its poles and bulges in the middle. The geoid is the term that rightfully describes the actual shape of the earth.

Question 16. Write a difference between latitudes and longitudes.

Answer 16:  Parallels of Latitudes are imaginary circular lines drawn horizontally between both the poles and the equator. Its direction is west to East. The angle of latitude varies from 0° at the Equator to 90° at the poles. They decrease in size from the middle of the earth toward the Poles. The angle between the equator and the latitude is measured in degrees (latitudes to the south are negative). On the other hand, longitudes are half circles that run from the north to the south. They are the same in size and converge at the Poles. There are a total number of 360 longitude lines. Longitude is an angle measured to the east from the prime meridian (longitudes to the west are negative).

Question  17. What is the Prime Meridian? 

Answer 17: Prime meridian is the central meridian running from the North Pole to the South Pole. It is given the value of 0°, and the counting of meridians begins from it. This meridian runs through the British Royal Observatory in Greenwich, United Kingdom.

Question 18. Describe the Tropic of cancer and the Tropic of Capricorn. 

Answer 18: The Tropic of Cancer and the Tropic of Capricorn are two significant latitudes. The Tropic of Cancer is situated at 23 ½ ° N in the Northern Hemisphere. The Tropic of Capricorn is located at 23 ½ ° S in the Southern Hemisphere.

Question 19. What are the three heat zones of the earth?

Answer 19: The three heat zones of the earth are –i) the torrid zone lies between the Tropic of Cancer and the Tropic of Capricorn and receives the maximum heat from the sun. It’s also known as the Tropical Zone.

 ii)The temperate zone lies between the tropic of Cancer and the Arctic circle in the Northern Hemisphere and between the Tropic of Capricorn in the Southern Hemisphere. Unlike the torrid zone, it receives less sunlight as the sun’s rays are slanting and have a moderate temperature. 

iii) The Frigid Zone receives less heat and the temperatures are very low. It’s also known as the polar region. It lies between the Arctic Circle and the North Pole in the Northern Hemisphere and between the Antarctic Circle and the South Pole in the Southern Hemisphere. 

Question 20. How does time differ with longitudes?

Answer 20: The earth rotates 360° in 24 hours. So, it covers 15° in 1 hour. Thus, the earth completes 1° in 4 minutes. So, time changes by 4 minutes with an interval of 1° longitude. In other words, the time differs by 1 hour with the interval of 15° longitude.

Question  21. What are the parallels between latitude and meridians of longitude?

Answer 21: The parallels of latitude are parallel circles which run from the west to the east. They decrease in size from the middle of the earth towards the Poles. . The largest parallel of latitude runs through the middle of the earth, bearing the value of 0°. It is also called the Equator. The parallels to the north of the Equator carry ‘north latitudes’. Similarly, all the parallels to the south of the Equator are called  ‘south latitudes’. .

Meridians of longitude are other reference lines which run from the North Pole to the South Pole. They are half circles which are the same in size. Total of 360 meridians with an interval of 1° cover the earth’s surface. Among them, The Prime Meridian is the 0° meridian passing through the British Royal Observatory in Greenwich, United Kingdom. Meridians are counted from this Prime Meridian. The Meridian and the Prime Meridian divide the earth into two equal halves- the Eastern Hemisphere and the Western Hemisphere. 

Question 22. What is standard time? Why is it important?

Answer 22:  Standard time is the local time of a central meridian of a country or a region. A country may have more than one local time. So, there will be variation in time in the country, creating problems with   train- timetables. For this purpose, standard time is taken so that there remains uniformity in time throughout the country. For example, in India, the difference in local times of its west most and east most places is 1 hour 45 minutes. So, the local time of 82 ½ ° E meridian has been taken as the standard time in India. The whole country follows the time of this meridian as the official time.

Question  23. Why does the torrid zone receive the maximum amount of heat?

Answer 23: Torrid zone lies between the Tropic of Cancer and the Tropic of Capricorn on the earth’s surface. In this region, on all latitudes, the mid-day sun is directly overhead at least once a year. Thus, this region receives direct and vertical sunlight throughout the year.  That’s why the torrid region receives the maximum heat and becomes the hottest zone. It’s also known as the tropical zone.

Question  24. How can we determine the location of a place on the earth’s surface?

Answer 24: The location on the earth’s surface is determined with the help of latitudes and longitudes. Latitudes are parallel circles running from the west to the east, whereas longitudes are half circles joining both the poles. Both latitudes and longitudes bear the value in degrees. The latitudes and longitudes intersect each other and form net-like structures, which are called the grid. We can determine the location of a place from this grid. One has to measure the values of latitude and longitude that pass through this place. The respective values indicate the position of that place on the earth’s surface. 

Question 25. Why is it 5.30 p.m. in India and 12.00 noon in London?

Answer 25: We know time changes at a rate of 1 hour with 15° longitude or 4 minutes with 1° longitude. India’s standard time is the local time of the meridian at 82 ½ °E. On the other hand, the standard time of London is Greenwich Mean Time or GMT. As the meridian is to the east of the Prime Meridian, the standard time of India is always ahead of Greenwich Mean Time (GMT). So the time difference between GMT and IST is (82 ½ * 4) minutes or 330 minutes, i.e. 5 Hours and 30 minutes. So, when the time is 12.00 p.m. in London, the time in India will be (12 p.m. + 5 ½ Hours) or 5.30 p.m.
