Historical Geology


It would be a real good idea to understand the following terms and concepts...

The "laws" of geology

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
