“It only appears that way, Veve. Instead, the sun shines upon dust and millions of water droplets already in the air. They reflect the sunshine and the rays show plainly against the cloudy sky.”
“But how did the water get into the air?” Veve asked.
“I’ll try to make it clear by a simple illustration. Did you ever leave a shallow pan filled with water out in the yard?”
“I guess so,” Veve admitted.
“And later the water nearly all disappeared?”
“That’s right. Danny, the dog that lives next door to us, drank it up!”
“Well, if Danny hadn’t come along, the water would have evaporated.”
“Oh, I’ve seen that happen,” Connie declared. “Once at our house a plant dish filled with water during a rain. A few days later every drop was gone.”
“But how does the water ’vaporate?” Veve demanded. “I never saw it happen.”
“The water separates into particles which are called molecules,” Eileen’s mother explained. “Molecules are too small to be seen. However, they turn into water vapor which is light enough to be carried away.”
