When I was a kid, I was always picking up rocks. They looked interesting. I guess that spurred my interest in Geology. It's fascinating to figure out how the world works. What causes earthquakes? What is plate tectonics? What was Pangea? Geology answers (or tries to) them all. That's what's so interesting.
