Absolute Dating | arrow_right_alt | techniques allow us to predict a numerical age or range for past events relatively accurately. |
Radiometric Dating | arrow_right_alt | Technique that relies heavily on looking at the radioactive elements in rocks and the decay that took over time. |
Igneous Rocks | arrow_right_alt | forms when magma cools down and solidifies and is useful for radiometric dating. |
Fossilization | arrow_right_alt | is the process by which remains or traces of past life give rise to fossils. |
Geologic Time Scale | arrow_right_alt | is a linear representation of the most important events that occurred over a period of time in Earth’s history. |

|---|---|---|
Fault | arrow_right_alt | is a crack or break in the rocks of the Earth’s crust which results in the displacement of the rocks on the opposite sides of the fracture. |
Principle of Superposition | arrow_right_alt | are fossils that are widespread geographically and can be used as time indicators to match rock layers of the same age. Often, they lived over a large area for a short period of time. |
Sedimentary Rocks | arrow_right_alt | The action of geologic processes, such as faults, folds, magma intrusions, or erosion, that move rock layers into different positions. |
Index Fossils | arrow_right_alt | infers that rock layers are ordered on the vertical axis by age; younger rock layers are above ↑ and older rock layers are below ↓. |
Relative Dating | arrow_right_alt | Technique that allows us to order events by looking at the oldest vs youngest rock layers. |
Rock Strata | arrow_right_alt | are horizontal ↔ rock layers originating from the accumulation or compaction of sediments that give rise to sedimentary rocks. |
Principle of Cross-cutting | arrow_right_alt | forms by compaction of rock fragments or remains of living organisms. Useful for relative dating techniques. |
