Another typo - called the moon phase a waning gibbons instead of gibbous. Gibbons are primates....not moon phases. For $50 a book, I expect someone to get an editor on this content.

Pg 35 section on sea floor spreading "the crust is several million years younger than the continental crust"

This is incorrect. Continental crust is several BILLIONS of years old whereas the oceanic crust is around 200-350 million years old.

Pg 26s section on sea floor spreading correctly explains this.

I should not have to fact check an instructional text like this. Especially a study book.
