Detailed explanation-1: -The Sun provides us with light and heat. It also gives out dangerous ultraviolet light which causes sunburn and may cause cancer. Without the Sun there would be no daylight, and our planet would simply be a dark, frozen world, with no oceans of liquid water and no life.
Detailed explanation-2: -Without the Sun’s heat and light, the Earth would be a lifeless ball of ice-coated rock. The Sun warms our seas, stirs our atmosphere, generates our weather patterns, and gives energy to the growing green plants that provide the food and oxygen for life on Earth.
Detailed explanation-3: -In space or on the Moon there is no atmosphere to scatter light. The light from the sun travels a straight line without scattering and all the colors stay together. Looking toward the sun we thus see a brilliant white light while looking away we would see only the darkness of empty space.
Detailed explanation-4: -We see the visible spectrum of light simply because the sun is made up of a hot gas – heat produces light just as it does in an incandescent light bulb.
Detailed explanation-5: -Unlike our Sun, the Moon doesn’t create its own light. We can only see it because light from the Sun is reflecting off of its surface.
