IX. Give Reasons :

Question 1.
The 0° line of longitude is called the Greenwich Meridian.
Answer:

1. All nations of the world agreed to have the Greenwich Meridian as the international Standard Meridian (0°).
2. This line of longitude is called the Prime Meridian and it is also known as the Greenwich Meridian because it passes through Greenwich.

Question 2.
The regions on Earth between North & South lines of latitude (66 V20) and poles (90°) is called Frigid Zone
Answer:
This region receives very slanting rays of the sun. The temperature is very low. Hence, this region is known as Frigid Zone.

Question 1
What are the uses of globe?
Answer:

1. Since the Earth is huge and we live on a very area, we are not able to see the Earth as a whole.
2. But when we travel to space, we can see the Earth as a whole.
3. So, in order to see the shape of the Earth as a whole and to know its unique features, a three dimensional model of the Earth was created with a specific scale in the name of globe.

Question 2.
How are the hemispheres divided on the basis of lines of latitude and longitude?
Explain with diagrams.
Answer:

Question 3.
What are the significant lines of latitude? Explain the zones found between them,
Answer:
The significant lines of latitude are
(a) Equator – 0°
(b) Tropic of Cancer – 23 1/2°N
(c) Tropic of Capricorn – 23 1/2°S
(d) Antarctic Circle – 66 1/2°S
(e) Arctic Circle – 66 1/2°N
(f) North Pole – 90°N
(g) South Pole – 90°S.

(i) Torrid zone:
The region from the Equator towards the Tropic of Cancer (231A°N) and the Tropic of Capricorn (23 1/2 40S) is called the Torrid Zone.

(ii) Temperate zone:
From the Tropic of Cancer (23!/2°N) to the Arctic Circle (661/2°N) and from the Tropic of Capricorn (23 1/2 0S) to the Antarctic Circle (661/2°S), the Sun’s rays fall slantingly. Moderate temperature prevails in this region. Hence, this region is called Temperate Zone.

(iii) Frigid zone:
From the Arctic Circle (66 1/2°N) to the North Pole (90°N) and from the Antarctic Circle (66 1/2 0S) to the South Pole (90°S), the Sun’s rays fall further inclined, throughout the year. Hence, this region is called Frigid Zone.

Question 4.
Explain; Indian Standard Time.
Answer:

1.  The longitudinal extend of India is from 68° 7’E to 97° 25’E
2. As many as twenty nine lines of longitude pass through India.
3. Having 29 standard time is not logical.
4. Hence 821/2° E line of longitude is observed as the prime meridian to calculate the Indian standard Time.
