The Role of the Sun
Life on Earth could not exist if it weren't for the sun. The sun is a big star that gives us light, heat and energy. Without it, plants wouldn't grow and the earth would be too cold for life to survive. When the sun shines, its heat gets trapped in our atmosphere. The atmosphere is an invisible layer of gas that surrounds the earth like a blanket of air. If the atmosphere didn't trap heat from the sun, our entire planet would be covered with ice!
