Atmospheric Layers Riddles Test

I protect the earth from ultraviolet rays given off by the sun. Who am I?_______________________________ Since this is a layers of the atmosphere test question, you would probably say, Stratosphere.

But, wait, the Thermosphere has a UV protection layer of nitrogen and oxygen, so, Thermosphere, could also be correct.

But, wait!!! Most of the protection from UV rays comes from the ozone layer, found in the Stratosphere. Well, that's correct, as well.

Oh, and, I asked five questions pertaining to the ionosphere and exosphere, but, ran out of time in reviewing them as part of our layers of the atmosphere review. So, I kinda gave them away as free answers (no credit, no penalty).

I suppose I should be tickled the cherubs know we live in the Troposphere, the Jet Streams are in the Stratosphere; the Mesosphere is known as the meteoroid catcher, and you can't measure the temperature of the Thermosphere with a bulb-thermometer.

The pH of water
I nailed my BASE group. I gave them a sample of tap water, distilled water, bottled water, and well water, and asked them to distinguish the water pH using 0-13 pH paper. "But, Mr. Z, they all came out as neutral!?!?! How are we supposed to know which one is which? " Neutral is 'twix 6.5 and 7.5. All those water samples fall within that range.

Ain't I a stinker?

Have a good night, folks.

So the Thermosphere and the Stratosphere would be correct????
