Relate radioactive dating techniques to isotopes

In the Grand Canyon, the layers of strata are nearly horizontal.Most sediment is either laid down horizontally in bodies of water like the oceans, or on land on the margins of streams and rivers.

The study of strata is called stratigraphyand using a few basic techniques, it is possible to work out the relative ages of rocks.There are three general approaches that allow scientists to date geological materials and answer datimg question: Relative dating puts geologic events in chronological order without requiring that a radioactive numerical age be assigned to each event.Second, it is possible to determine the numerical age for fossils or earth materials.The techniques of original horizontality, superposition, and cross-cutting relationships allow events to be radioactive at a raduoactive location.However, they do not reveal the relative radioactibe of rocks preserved in two different areas.

Each technique a new layer of sediment is deposited it is laid down horizontally on top of an older layer.
