Historical Geology
It would be a real good idea to understand the following terms and concepts...
Uniformity: the present is the key to the past
Original Horizontality: sedimentary layers are initially deposited in horizontal layers
Superposition: the layer on the bottom is the oldest, and they get younger as they pile up.
Cross-cutting relationships: the thing being cut is older that the thing doing the cutting
