Seasons

Seasons are caused by the tilt of Earth's axis as it revolves around the sun. During the Summer the Sun's rays are more direct. Also, the Sun is higher in the sky and the days are longer. When it's Autumn or Spring, daytime hours and nighttime hours are relatively equal. In the winter, there is very little direct sunlight and the days are shorter. as the Earth moves around the sun, the place on earth that receives the most direct sunlight changes. The more direct sunlight, the higher the solar energy, and the hotter the weather.
