Sunlight energy reaches the Earth, the amount depending where you are. At the equator at midday enough energy reaches each square meter of the Earth's surface to power a 1 kilowatt bar of an electric fire. Because of the curvature of the Earth, the amount of energy falls off as you move nearer to the poles.
This variation in sunlight causes the variation in the climate in different parts of the Earth. Sunlight may have played a part in the evolution of life. Sunlight is a form of radiation. |
