Reasons for Seasons 1. Tilt of the Earth - the tilt of the earth stays the same as the Earth revolves around the sun.

  1. Angle of Incidence - Due to tilt and curvature of Earth's surface, sunlight strikes the surface of the Earth at difference angles, producing zones of direct light and zones of diffuse light.
  2. Hours of daylight - more hours of daylight produce summer months and fewer hours of daylight produce winter months. Locations with smaller latitude numbers have less variation in their lowest and highest daylight hours. Locations with larger latitude numbers have great variation in their daylight hours.

Direct sunlight Light from the sun directly hits the surface of the Earth, creating more concentrated heating.

Diffuse sunlight Light from the sun hits the surface of the Earth at an angle, causing it to be less concentrated and thus less heating occurs.

Tropic of Cancer 23.5 degrees north latitude; location of direct sunlight during the summer solstice.

Tropic of Capricorn 23.5 degrees south latitude; location of direct sunlight during the winter solstice.
