How much sunlight does an average Earth day receive?

Answer 1

Every place on earth averages 12 hours of daylight and 12 hours of darkness. Each pole which is the farthest away from the equator receives an equal amount, but it comes in bunches of six month periods due to the angle of inclination which is 28.5 degrees. The only place where the 12 hour daylight and 12 hour darkness is constant is at the equator and from the Tropic of Cancer going north and the Tropic of Capricorn going south the days and nights begin to stretch and shrink through the seasons until we reach that six month day and six month night at the poles. Hence, Tampa Florida has twelve hours on the average of daily sunlight and so does Madison Wisconsin, but the differences come with the distance from the equator which gives Madison shorter winter sun and longer summer sun than Tampa Florida. The growing season is shorter in Madison than in Tampa, but it evens out so that both have a pretty comparable growing season due to the extension of daylight hours in Madison.
