Be careful, once you go down the geology rabbit hole you find it is really deep and you just have to keep digging.
A good college textbook that was recommended by
@Georgia Yankee is "Earth: Portrait of a Planet" by Marshack. I got an old edition for a reasonable price about a year ago. I highly recommend a real book if you want to learn. It would not help you with what you are seeing, but would give you a basic understanding to build on.
An awesome book is "Annals of the Former World" by John Mcphee. It is about geology and the plate tectonic revolution in the late 60s. It also has lots of interesting history. Great book.
