Little Johnny, after a science lesson on the laws of gravity, returned home, determined to prove his teacher Mr. Knowles wrong.

"Not everything that goes up comes back down, and I'll prove it!" After some brainstorming, he placed a bowl of water in the 12PM, windless, Sunday sun, and watched as it evapourated. "It all went up," he said.

The next day at school, he confronted his teacher about his little science project. But Mr. Knowles told Little Johnny that he was a bit short sighted. How so?



Answer

Little Johnny was short sighted because he had not waited to see the water come back down a few days later as rain or some other form of precipitation.(even if advection took place, the water would still come back down). Little Johnny should have consulted his geography teacher before doing the experiment. He would have learnt about the water cycle.

I somewhat knew that the (evaporated) wat would come down. It's a part of the water cycle!

I said that the water going up wasn't really anti-gravity because it was hotter.
