Most of our questions above can be answered by understanding how our planet and our Sun relate to each other. The shape of our planet, the way it rotates, and its position in relation to the Sun all have something to do with our questions. Our planet is a spherical shape, that is, it is almost round like a ball.
Sunlight radiates to the earth.
This radiation provides light, heat, and other types of electromagnetic energy. Earth, while revolving, also rotates on an axis. The earth's axis is tilted in relationship to the Sun. All of these things are major factors in understanding long days, high noon and why Randy and Janice will be shivering at the South Pole. Never look directly at the Sun.
