What effect does the Sun have on Earth?
The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis. Without the sun’s heat and light, life on Earth would not exist.
How bad is the Sun for your skin?
The sun radiates light to the earth, and part of that light consists of invisible UV rays. When these rays reach the skin, they cause tanning, burning, and other skin damage.

Your risk increases based on the length and depth of exposure. You are at greater risk if you have fair skin or moles.
What happens to the Earth if there is no sun?
Electricity would still work, and it would still take up to an hour for the light from our planets to be reflected back to Earth, so there would be a peaceful glow in the sky. With no sunlight, photosynthesis would stop, but that would only kill some of the plants —there are some larger trees that can survive for decades without it.
Can a person get skin cancer from the Sun?
Although the skin appears to be thicker, it actually has been weakened and, as a result, it will bruise more easily. However, the sun’s most serious threat is that it is the major cause of skin cancer, which is now the most common of all cancers. Doctors believe that most skin cancers can be avoided by preventing sun damage.
