1. They tell the absolute of the
rock.
2. They tell the ages of MANY rock
layers in different locations
3. They tell how the fossil was
formed.
4. They tell the EXACT age of the
entire rock layer.

1. Its age compared to other rocks or
fossils.
2. The number of years since it
formed.
3. Its age as determined by carbon
dating.

1. A break in the rock
2. Layers of rocks bend or curve
3. When magma pushes through
rock layers
4. When lava reaches the surface.
This law states that layers of sediment
were originally deposited horizontally
under the action of gravity.

1 Sedimentary layer of D was created.
1 Sedimentary layer of H was created
1 Sedimentary layer of A was created
Layers D, H, and A are compressed and bent to form folds.
An intrusion C cuts through layers D,H and A but not to the
surface.
A fault G cuts through layers D, H, A and the Intrusion C.
1 Sedimentary Layer F was created
1 Sedimentary layer I was created
1 Sedimentary layer B was created
Layers F, I, B are uplifted and titled.
1 Sedimentary layer of E was created.
Cross Cuts- C Intrusion, G is a Fault
UnconformitiesNonconformities between lines D and C, F and C
Disconformities between lines D and H, H and A
Angular Unconformities between lines F and E, I and E, and B and E
