Here’s a little guy who hopefully will help you remember the layers of our atmosphere.
Exosphere: There’s not much in the head of this person. But will give the molecules x’s and o’s (kisses and hugs) before they leave our atmosphere.
Thermosphere: The arms are great for holding a thermos and absorbing all those x-ray and UV light from the sun.
Mesosphere: It’s the meatier (meteor) part of the body where we are mesmerized by the shooting stars as the meteors burn up.
Stratosphere: The person is straddling the world. Unfortunately stuff is oozing out of his legs Must be the oozing zone where ozone resides.
Troposphere: It’s the tropical rainforest. Oh I see. And of course that’s where most of the water are in our atmosphere.
BTW, I thought of this mnemonic from the bottom up, so might be easier to lean in that direction as well. Enjoy!
