NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes

Q1. Answer the following questions briefly.
(a) What is the true shape of the Earth?
Ans: The Earth is not a perfect sphere. It is slightly flattened at the North and the South Poles and bulge in the middle.

(e) What are parallels of latitude and meridians of longitude?
Ans: All imaginary parallel circles from the equator to the poles are called parallels of latitude. The imaginary set of semi-circle lines that run from the North Pole to the South Pole are called meridians of longitude.

(f) Why does the Torrid zone receive maximum amount of heat?
Ans: The Sun shines perpendicular between the Tropic of Cancer and the Tropic of Capricorn throughout the year. Perpendicular sun rays give more heat than slanting sun rays. Therefore, the Torrid Zone receives the maximum amount of heat.

(g) Why is it 5.30 p.m. in India and 12.00 noon in London?
Ans: 

  • India and the United Kingdom are situated on different longitudes, which leads to a difference in their local times. The Earth rotates 360 degrees in 24 hours, which means it covers 1 degree of longitude in 4 minutes. Therefore, every degree of longitude corresponds to a 4-minute difference in time.
  • London is located at 0° longitude, while the standard meridian of India is 82°30' E longitude. This difference in longitude results in a time difference between the two locations. Since India is to the east of London, time in India is ahead. For every degree eastward, time increases by 4 minutes.
  • Calculating for the 82°30' E longitude, the time difference between London and India is:
    82.5 degrees x 4 minutes per degree = 330 minutes or 5 hours and 30 minutes.
  • So, when it is 12 noon in London, it is 5:30 PM in India.

(iii) 90
Ans:
(ii) 180

NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes  View Answer

Longitudes are semicircles that meet at the poles, and there are 180 degrees of longitude east and 180 degrees west of the Prime Meridian.

(d) The Antarctic Circle is Located in 
(i) The Northern hemisphere 

(ii) The Southern hemisphere 
(iii) The Eastern hemisphere
Ans: 
(ii) The Southern hemisphere 

NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes  View Answer

The Antarctic Circle is situated in the Southern Hemisphere, at 66½° south of the equator.

(e) Grid is a Network of 
(i) Parallels of latitudes and Meridians of longitudes 

(ii) The Tropic of Cancer and The Tropic of Capricorn 
(iii) The North Pole and the South Pole
Ans:
(i) Parallels of latitudes and Meridians of longitudes

NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes  View Answer

A grid is formed by the intersection of parallels of latitude and meridians of longitude, helping in the precise location of places on the globe.


Q3. Fill in the blanks.
(a) The Tropic of Capricorn is located at _____.
Ans: 23.5 Degrees south of the Equator

NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes  View Answer
  • The Tropic of Capricorn is an important latitude line situated at 23.5° south. 
  • It marks the southernmost point where the Sun can be directly overhead, which happens during the December solstice.

(b) The Standard Meridian of India is _____.
Ans: 82½ Degrees E

NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes  View Answer
  • India's standard time is based on the longitude of 82.5° E, known as the Standard Meridian of India. 
  • This line of longitude was chosen to have a single time zone for the whole country and is 5 hours and 30 minutes ahead of GMT (Greenwich Mean Time).

(c) The 0° Meridian is also known as _____.
Ans: Prime Meridian

NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes  View Answer
  • The Prime Meridian is the starting point for measuring longitude and is set at 0°. 
  • It runs through Greenwich, London, and divides the Earth into the Eastern and Western Hemispheres.

(d) The distance between the longitudes decreases towards _____.
Ans: Poles

NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes  View Answer
  • Longitude lines, which run from the North Pole to the South Pole, are widest at the Equator. 
  • As they approach the poles, these lines converge, reducing the distance between them.

(e) The Arctic Circle is located in the _____ hemisphere.
Ans: Northern

NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes  View Answer
  • The Arctic Circle is an imaginary line located at approximately 66.5° north of the Equator, within the Northern Hemisphere. 
  • It marks the region where, for at least one day each year, there is continuous daylight or darkness.

FAQs on NCERT Solutions for Class 6 Geography - Globe - Latitudes and Longitudes

1. Globe पर अक्षांश और देशांतर क्या होते हैं?
Ans. अक्षांश और देशांतर पृथ्वी की सतह पर स्थान को निर्धारित करने के लिए उपयोग किए जाने वाले दो प्रमुख ग्रिड हैं। अक्षांश उत्तरी और दक्षिणी गोलार्धों के बीच की रेखाएं हैं, जबकि देशांतर पूर्वी और पश्चिमी गोलार्धों के बीच की रेखाएं होती हैं। अक्षांश को 0° से 90° तक मापा जाता है, जबकि देशांतर को 0° से 180° तक मापा जाता है।
2. अक्षांश और देशांतर का महत्व क्या है?
Ans. अक्षांश और देशांतर का महत्व यह है कि इनकी मदद से हम किसी विशेष स्थान को सटीकता से पहचान सकते हैं। यह नेविगेशन, भूगोल, जलवायु अध्ययन और मानचित्र निर्माण में अत्यधिक उपयोगी होते हैं। इसके अलावा, ये वैश्विक स्तर पर स्थान के समन्वय के लिए आवश्यक होते हैं।
3. अक्षांश रेखाएं किस दिशा में फैली होती हैं?
Ans. अक्षांश रेखाएं पूर्व से पश्चिम की ओर फैली होती हैं और इन्हें समानांतर रेखाएं भी कहा जाता है। ये रेखाएं पृथ्वी के गोल आकार के चारों ओर समांतर रूप से चलती हैं और 0° (एक्वेटर) से शुरू होकर 90° (उत्तर और दक्षिण ध्रुव) तक जाती हैं।
4. देशांतर रेखाएं कैसे होती हैं?
Ans. देशांतर रेखाएं उत्तर से दक्षिण की ओर फैली होती हैं और इन्हें मेरिडियन भी कहा जाता है। ये रेखाएं पृथ्वी के ध्रुवों को जोड़ती हैं और 0° (ग्रीनविच) से शुरू होकर 180° तक जाती हैं। देशांतर रेखाएं एक दूसरे को 90° पर काटती हैं।
5. Globe पर अक्षांश और देशांतर को कैसे समझा जा सकता है?
Ans. Globe पर अक्षांश और देशांतर को समझने के लिए, हमें Globe को ध्यान से देखना होगा। Globe पर अक्षांश रेखाएं समानांतर होती हैं और देशांतर रेखाएं एक-दूसरे को काटती हैं। इस तरह, हम किसी भी स्थान का अक्षांश और देशांतर जानकर उसे आसानी से पहचान सकते हैं।
