Not too easy. Not too difficult.
The Professor is very motivated and really knows what he is teaching, as well as being very open to questions and quick to respond to emails. As long as you pay attention during lecture and study the study guides, you should be fine.
The class gave me a solid foundation of Earth Science knowledge, and was enjoyable enough to recommend to even non-majors.

Advice for students:
Make sure you pay attention during lecture and study each of the study guides he gives. Those guides will have almost everything you need. I never really used the textbook.
