The sun produces light through a process of constant nuclear reaction in which atoms interact and produce high levels of energy. Human beings can feel the effects of this reaction as it produces both heat and light energy.Continue Reading
The energy of the sun is essential for life on Earth since it facilitates various processes like the manufacturing of food by plants. Some animals cannot see in the dark and thus have to take advantage of the sun's light to feed or engage in other activities. The sun also produces heat energy that helps maintain temperatures on Earth within conducive limits for any form of life.
The sun is a star situated lower than other stars, which is why it appears larger and shines more than any other object in the sky. It is made up of large amounts of hydrogen gas that constantly transforms into helium, causing energy production that results into light and heat. The light from the sun takes about 8 minutes to reach the Earth
