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 Cross-Cutting Relationships?

• 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

What is Relative Age Dating?

• The dating of rocks in how they compare to the rocks that are around them.

• The use of fossils to help find the age of a rock.

• The use of radioactive elements in rock to find a highly accurate estimate of the age of the rock.

• Dating of a rock layer based on how far it is from Earth's core.
