I know that the sky is blue because of the scattering of sunlight by the Earth’s atmosphere. Also, rainbows are formed when sunlight passes through raindrops and is refracted and reflected. Another fact is that plants perform photosynthesis, which is how they make food using sunlight, carbon - dioxide and water.
