When the sun goes back behind the clouds and no longer shines through the moisture such as rain in the sky. Thats what creates a rainbow. Loke the sun shing through a crystal pendant or prism refracts and reflects making a rainbow effect. If you take the crystal out of the sun , the rainbows go away. When the sun hides behind a cloud, the rainbow fades and then goes away as it needs the sun to make a rainbow. Usually rainbows only last a few minutes because the clouds and the moisture and the sun must be in just the right place for us to see them. So they are rather rare as the weather has to be just right to see one. I hope I answered your question. Forgive any typos please as i am using an ipad. Lol. Keep chasing those rainbows-

And have a nice day!
