Stratigraphy Practice

What is the Law of Superposition?

• All principle that states that rock layers were formed as horizontal layers

• A gap in rock layers due to erosion of a weak layer of rock

• A principle that states that an intrusive layer of igneous rock will always be younger than the rock it cuts through.

• A principle that states that the deeper a rock is, the older it is unless it has been disturbed or altered.

What is the Law of Original Horizontality?

• All principle that states that rock layers were formed as flat layers

• A gap in rock layers due to erosion of a weak layer of rock

• A principle that states that an intrusive layer of igneous rock will always be younger than the rock it cuts through.

• A principle that states that the deeper a rock is, the older it is unless it has been disturbed or altered.
