��CLASS : VI��Subject: GEOGRAPHY��TOPIC:- �GLOBE : LATITUDES AND LONGITUDES

LONGITUDE AND TIME

WHY DO WE HAVE STANDARD TIME?

• In India, the longitude of 82½° 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.
• 97 – 68 = 29 longitudes
• 29 ÷ 2 = 14.5
• 97 – 14.5 = 82.5
• 68 + 14.5 = 82.5

RECAP QUESTION

1. How many longitudes pass in an hour from the Sun?
2. If a cricket match in England starts at 9:00 AM as per its local time, then what will be the time of the same match in India?
3. Can you determine IST (Indian Standard Time) using its Eastern 97°E and Western 68°E Longitudes.
4. Why Eastern and Western side longitudes of Prime Meridian should consider ahead and behind time respectively?

SUMMARY of the CHAPTER

• Earth is slightly flattened at the North and the South Poles and bulge in the middle.
• Globe is a true model (miniature form) of the earth.
• The three heat zones of the Earth are Torrid Zone, Temperate Zone and Frigid Zone.
• 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 North Pole to South Pole are called meridians of longitude.
•  Torrid zone lies between the Tropic of Cancer and Tropic of Capricorn. The mid-day sun is exactly overhead at least once a year on all latitudes in this area. Therefore, torrid zone receive maximum amount of heat.
•  London is situated at 0º longitude i.e., Greenwich mean time (GMT). India located east of Greenwich at 82° 30' E is 5 hours and 30 minutes ahead of GMT. Sp, when it is 5.30 p.m. in India, it is 12.00 noon in London.
