Answer:
hello friends if you have any questions or need any further information
1) North pole & South pole
2)The North frigid zone, between the Arctic Circle 66.5° N and the North Pole 90° N. Covers 4.12% of Earth's surface. The North temperate zone, between the Tropic of Cancer 23.5° N and the Arctic Circle 66.5° N. Covers 25.99% of Earth'ssurface.
3)The torrid zone receives the maximum amount of heat throughout the year because the rays of the sun fall vertcally on this regon. This is located between the tropic of Cancer and Tropic of Capricorn in 23 1/2N to 23 1/2 S.
4)As the reference for GMT, the Prime Meridian at Greenwich therefore became the centre of world time and the basis for the global system of time zones. ... It was recommended that the meridian line would indicate 0° longitude. Therefore this also became the start of the Universal Day.
5)Because 15 degrees of longitude is equivalent to 1 hour in time (that is 360 / 24) it is convenient to adopt time zones at 7.5 degrees
1)Latitude is the angular distance of a place north or south of the Equator
There are 180 parallels of latitudes apart from the Equator.
Each parallel of latitude is a circle
2)Standard time is the transpiration of timers within a geographic territory or region to a different time standard, rather than employing solar time or a regionally fixed time (longitude) to set a local mean time standard. ... Consequently, the standard time for India has been taken from Mirzapur for the entire nation.
