Quizplus · Accepted Answer

Latitude determines the angle at which the sun's rays hit the Earth's surface, and thus has the greatest effect on the amount of incoming light that strikes an area. The closer a location is to the equator, the more direct the sunlight and the more intense the light energy. Conversely, the further away from the equator a location is, the more indirect the sunlight and the less intense the light energy. Temperature, humidity, the ozone layer, and wind patterns can all affect the amount of incoming light to some degree, but they are not as significant as latitude.
