Test 9 - Age of Earth/Rock Cycle

method used to determine the age of rocks by comparing rocks with younger and older rock layers

• absolute dating

• fossil record

• relative dating

• radioactive decay

A principle that states that younger rocks lie above older rocks if the layers have not been disturbed.

• Theory of Plate Tectonics

• Law of Superposition

• Theory of Cross Cutting Relationships

• Theory of Unconformities

According to the law of superposition, which layer is the youngest?

• A
• B
• C
