Sene 14 and June 21 are called unlike days of the Tropics and Temperates

Editor's Notes

1. The beauties of day and night of Sene 14 and June 21 are dissimilar   The beauty of day and night is 24 hours of the day is divided between 12 hours of daylight and 12 hours of night. This is always true for the entire earth. Half part of the earth that turns its face to the sun gets daylight and the other half part that gets no light is called night. The equilibrium is the equator in which 24 hours of the day is exactly equal to 12 hours daylight and 12 hours night. Equator is the greatest circumference of the earth that measures about 40,076.6 KM. Tropic of Cancer or Capricorn is greater circumference of the earth that measures 36,752.65 KM and Upper or lower boundary of Temperate is called great circle that measures about 15,980.5KM. The north flat part of the earth is called North Pole and south flat part of the earth is called South Pole. Thus areas of earth less than greater circumference and greater than or equal to great circumference is called Temperates. Temperates are divided into north Temperate and south Temperate. The bulged areas of earth which is less than the greatest circumference and more than or equal to greater circumference is called Tropics. The Tropics are divided into north Tropic and south Tropic. Here I divided the spherical earth into six zones. This means that it is both natural and scientific to make six zones of earth. 3 zones are found to be north of the equator: Zone 1 is North Pole, zone 2 is called north Temperate, zone 3 is north Tropic. Symmetrically, 3 zones are found to be south of the equator: zone 4 is called south Tropic, zone 5 is called south Temperate and zone 6 is called South Pole (look at Figure 1.1below).   If we see the day when the sun is overhead at the Tropic of Cancer, the beautiful shape of day and night is observed on Figure 2.1. The left side of Figure 2.1 shows that the beauty of daylight hours varies from the longest to longer and long in the North Pole, Temperate and Tropic and short, shorter and shortest length in the south Tropic, Temperate and Pole respectively. Whereas the right side of Figure 2.1 shows that the beauty of night varies from the shortest, shorter and short length in the North Pole, Temperate and Tropic, when long, longer and the longest hours in south Tropic, Temperate and Pole respectively.   First let analyze the beauty of daylight from the left side of the Globe, North Pole gets 24 hours daylight and no light. North Temperate gets the longer daylight hours that covers less than 24 hours and greater than 13.35 hours (length of daylight hours at Muscat). North Tropic gets long day light hours that lies less than or equal to 13.35 hours and greater than 12 hours. South Tropic gets short daylight hours slightly shorter than 12 hours and greater than or equal to 10.25 hours (the short daylight hours at Sao Polo). South Temperate gets shorter daylight hours that covers less than 10.25 hours and greater than or equal to 0 daylight hours. South Pole gets the shortest daylight hours that measures zero. When we observe the night side of the Earth, we get the opposite of daylight hours we discussed in the above paragraph. Since we discuss the day when the sun is found on the Tropic of Cancer, North Pole gets the shortest night (24 hours day light). North Temperate gets shorter night that covers less than or equal to 24 and less than 10.25. North Tropic gets short night that covers less than or equal to 10.25 and greater than 12 hours. South Tropic gets long night that covers between 12 hours and 13.35 hours. South Temperate gets longer night the covers greater than 13.35 and less than or equal to 24 hours. South Pole gets the longest night that covers 24 hours. In the 5th century bc, the Greek philosopher Parmenides proposed the division of the world into five zones, separated by lines of latitude. These divisions included a torrid zone between the Tropic of Cancer (about 23 y° N) and the Tropic of Capricorn (about 23 y° S); the north and south temperate zones between the tropics and the polar circles (66 y° N and S); and the north and south frigid zones, which lie between the polar circles and the poles. This system excluded other factors relevant to climate, such as differences in elevation, the proximity of oceans, levels of precipitation, and movement of air masses. The distribution of climate and biomes, or ecological communities such as deserts or rain forests, is therefore considerably more complex than these five zones suggest.
