Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds.
The major features of Copernican theory are: Heavenly motions are uniform, eternal, and circular or compounded of several circles (epicycles). The center of the universe is near the Sun. Around the Sun, in order, are Mercury, Venus, the Earth and Moon, Mars, Jupiter, Saturn, and the fixed stars.
Allows calculation of planetary orbital periods around Sun. Allows geometric calculations of planetary distances from Sun. These show nice regularity: more distant planets have longer periods, move slower. Easier to calculate planetary positions than with Ptolemaic model.
The flooding of the Nile was so important to the Egyptian civilization because the thick rich mud was excellent soil. This made it great for them because they could plant seeds in it and grow crops.
The peasants would be unable to provide enough for the quotas and so their goods were simply taken away from them and instead were given to the cities and the military. Millions of peasants as a result would starve to death and would end up moving to the cities where all of the food was being sent.Explanation:
