Today’s Agenda:
Agenda/Bell work
Stratigraphy
Objective:
Today we will be able to use stratigraphy to map out the layers of rocks
Daily Question:
How do you think scientists know the relative age of rocks?

2. Vocab:
relative dating: the science of determining the order of past events.
outcrop: a visible exposure of ancient rock.
strata: layers of rock (“stratum” is singular, “strata” is plural)
stratigraphy: a branch of geology which studies sedimentary rock layers.

3. 4 Geologic Principles:
Law of superposition - Sedimentary layers are deposited in a time sequence, with the oldest on the bottom and the youngest on the top
Law of crosscutting relationships -  states that the geologic feature which cuts another is the younger of the two features
Law of inclusions -  if a rock body contained fragments of another rock body, it must be younger than the fragments of rock it contained.
Law of faunal succession – observation that fossils follow each other in a predictable manner. Sequences are successive and correspond to their strata.

8. Law of lateral continuity Law of original horizontality state
While reading & filling out the worksheet, put the following terms in your notebook:
Uniformitarianism
Law of lateral continuity
Law of original horizontality state
Unconformity
