Summer progresses to fall The length of day (versus night) DECREASES.

3 factors create the season… The revolution of the Earth around the sun changes its position relative to the sun. As it revolves around the sun, the tilt of the Earth also changes in respect to the sun. If the Earth’s hemisphere is tilted towards the sun it is summer time. If the Earth’s hemisphere is tilted away from the sun it is winter time. The strength of the sun’s rays will be different at different latitudes because the Earth’s surface is curved. If the sun’s rays hit the Earth at 90 degree angle, it is called a direct ray – this produces the most intense energy. If the sun’s rays hit the Earth at angle less than 90 degree angle it is called an indirect ray. The higher angle indirect rays will be more intense than the lower angle indirect rays.
