Ans:  Towards the pole - The distance between each line of longitude gets less as you get closer to the poles, until they converge at the North and South Poles.

2. State true and false. 

(i) IST is Indian Standard Time

Ans: True - With a time offset of UTC+05:30, Indian Standard Time is observed throughout India.

(ii) There are lines of references running from the North to the South Pole.

3. Match the following:-

Ans: 

1. South Equator - The Tropic of Capricorn is located around 23°27′ south of the terrestrial Equator. This latitude corresponds to the Sun's ecliptic's southernmost declination relative to the celestial equator.

3. Indian Standard Time - With a time offset of UTC+05:30, Indian Standard Time (IST) is observed throughout India. India does not observe any seasonal changes, including daylight saving time.

4. Near the Poles - Near the poles is the Frigid Zone. The Polar Regions have a particularly chilly environment, which is why they are known as the Frigid Zone.

4. Choose the correct option 

(i) The total number of longitudes are__________. 

1. 720 

2. 360 

3. 180 

4. 60 

Ans: 360 - Longitude lines that travel from the north pole to the south pole form full circles, covering 360 degrees, which is why there are 360 longitudes.

(ii) The Antarctica circle is located in________. 

1. The Southern Hemisphere 

2. The Northern Hemisphere 

3. The Eastern Hemisphere 

4. None of the above 

Ans: Southern Hemisphere - At approximately 66.5 degrees south of the equator, the Antarctic Circle is a parallel of latitude on the Earth.

5. Define the Following 

(i) South Pole 

Ans: At 900 degrees S, the South Pole is located in the southern hemisphere.

(ii) Antarctic Circle 

Ans: At 66½ *C, the Antarctic Circle is located south of the equator.

6. Write the position of North Temperate Zone. 

Ans: From the Tropic of Cancer (about 23.5° north latitude) to the Arctic Circle (roughly 66.5° north latitude), the north temperate zone exists.

7. What is the importance of the globe? 

Ans: On a little ball, the globe allows us to comprehend the entire planet. It aids in the proper comprehension of various aspects of the world.

8. How pole star can be useful to find latitude? 

Ans: For example, the Pole star will be around 52 degrees above the horizon from southern England, indicating a latitude of 52 degrees north. Near the North Pole, Polaris will be straight overhead, while at the Equator, it will be on the horizon.

9. Why do you think temperate zone has moderate climate conditions? 

Ans: Since it is located away from the equator, the temperate zone features mild climatic conditions.

10. Why equator is important? 

Ans: The equator serves as a reference point for locating various locations.

11. Where does the Frigid Zone lie? 

Ans: The coldest zones are the frigid zones. Near the poles is the Frigid Zone. This is the area between the Arctic Circle and the North Pole in the northern hemisphere. This is the area between the Antarctic Circle and the South Pole in the southern hemisphere. The sun rays are continually slanting in this direction, and there is very little heat.

12. What is Prime Meridian? 

Ans: The Prime Meridian is said to be the reference point, with a longitude of 0 degrees. We have 180 degrees eastward and 180 degrees westward from this prime Meridian. The earth is supposed to be divided into equal halves by the prime meridian and the 180 degree meridian.

13. Which are the four parallel latitudes? 

Ans: There are four key latitude parallels. The Tropic of Cancer is located in the northern hemisphere, the Tropic of Capricorn is located in the southern hemisphere, the arctic circle is located at 66 degrees north of the equator, and the Antarctic Circle is located at 66 degrees south of the equator.

14. What are latitudes? 

Ans: Longitudes are perpendicular lines to the equator, while latitudes are parallel lines to the equator. Knowing the latitude and longitude of any spot on the globe makes it simple to locate it.

15. What is 0° Meridian? 

Ans: All countries agreed that the meridian that passes through Greenwich, where the British Royal Observatory is located, is the starting point for counting longitudes. The Prime Meridian was defined as a meridian with a value of 0 degrees.

16. Explain about the three heat zones of the earth. 

Ans: The earth's three heat zones are:-

1. Torrid Zone -The Torrid Zone is the region between the Tropics of Cancer and Capricorn that receives the highest heat.

2. Temperate Zone - This is the area in the northern hemisphere between the Tropic of Cancer and the Arctic Circle, and in the southern hemisphere between the Antarctic Circle and the Tropic of Capricorn. The temperature is moderate.

3. Frigid Zone - This part of the world is quite chilly. In the northern hemisphere, this is the area between the Arctic Circle and the North Pole, while in the southern hemisphere, it is the area between the Antarctic Circle and the South Pole.

17. What are the meridians of longitude and parallels of latitude? 

Ans: The imaginary line that separates the planet into the Northern and Southern Hemispheres is known as the Equator. By 0 degrees latitude, the equator is represented. The North Pole is located at 90° north latitude, whereas the South Pole is located at 90° south latitude. The world is divided into equal halves by this circular line. From the equator to the poles, there are parallel circles. The measurement units for latitudes are degrees.

18. Torrid zones receive maximum amount of heat, why? 

Ans: The Torrid Zone is located between the Tropics of Cancer and Capricorn. On all of the latitudes included in this area, the midday sun is directly overhead once a year. This occurs as a result of the fact that this area receives the most heat. Because the sun's rays fall vertically on this region, the torrid zone receives the most heat throughout the year. It is between the Tropics of Cancer and Capricorn, between 23 1/2N and 23 1/2S.

19. Why is having a standard time is necessary? Define IST. 

Ans: Indian Standard Time is abbreviated as IST. Every country must have a standard time zone. The following things will help to understand it:-

1. Time zones are important when creating a schedule for trains and aircraft. It's difficult to build a time table without a common time because different time zones have different times.

2. Standard time also aids in maintaining time consistency across the country.
   
   

The standard meridian is located at a longitude of 82°30'E and is known as IST (Indian Standard Time). This meridian is used to calculate India's standard time.

20. What is the Meridian that is taken as the standard time of India? 

Ans: In India, 82° 30' E is regarded as a standard meridian because the time difference between 1° longitude and 82° 30' E is 4 minutes.

The whole longitudinal space of India is 30 degrees (97°E-67°E=30°E). As a result of the total time difference of 30X4=120 minutes or 2 hours, the time difference between Gujarat and Arunachal Pradesh is 2 hours.

We chose a standard meridian to avoid such confusion and to ensure that everyone in the country is on the same time.
