Handouts

Our collection of 18 handouts totaling 200+ pages closely follows the official USESO syllabus and covers the major topics that show up on the exam. For your convenience, we have divided our handouts in the same fashion as USESO, into four sections: geosphere, atmosphere, hydrosphere, and astronomy. It is key to remember that earth science is all about interactions between the spheres, thus sphere-to-sphere interactions should be especially paid attention to for both students and earth scientists alike.
