This was an exercise in illustration to produce something magazine worthy. I have always admired earth cutaways and decided to do one of my own.
I have recently had help from Dr. Hugh O’Brien, Senior Geologist at the Geological Survey of Finland. He has been advising me on the dimensions and composition of the Earth.
I’d like to thank Hugh for his help, and all the other educators who have chosen to use my image in their classrooms and presentations.
