Explanation:

1. Finding the absolute age of rock by looking at the rate of decay: Radioactive Dating is a method that uses the decay - rate of radioactive isotopes to determine the age of rocks.
2. An igneous rock layer formed when lava flows onto Earth's surface and hardens: Extrusion refers to the formation of igneous rock from lava that cools on the Earth's surface.
3. An igneous rock layer formed when magma hardens beneath Earth's surface: Intrusion is the process where magma cools and solidifies below the Earth's surface to form igneous rock.
4. Principle stating that a fault or intrusion is younger than the rock it cuts across: The Law of Cross - Cutting Relationships states that any geological feature that cuts across another is younger than the feature it cuts.
5. Layers of sedimentary rock: Rock Strata are layers of sedimentary rock.

Answer:

1. Radioactive Dating
2. Extrusion
3. Intrusion
4. Law of Cross - Cutting Relationships
5. Rock Strata
