Can you name layers of the atmosphere? Where do geostationary satellites stay? What is molten, the inner core or the outer core? These simple 5th grade questions can leave you stumped someday.

We all left school long ago but these technical terms seemed to have pledged to haunt us everytime. Every now and then, we discuss something about the Earth and we are at a loss of words  to explain what we really mean. So, if you want to really know the Earth, here is a simple poster on Etsy that you can buy and put up on your wall. Other than helping you learn the Layers of the Earth, this hand made poster also makes for a great decoration in the house and even gets your nerdy side out.
