Relative Dating. To . determine the relative age of different rocks, geologists start with the assumption that unless something has happened, in a sequence of sedimentary rock layers, the newer rock layers will be on top of older ones. This is called the Rule of Superposition.. https://. www.youtube.com/watch?v=rQx2wLyagk4. . Essential Question:. How are layers of the Earth different from one another?. Standard:. S6E5a.

How are layers of the Earth different from one another?. Standard:. S6E5a. Compare and contrast the Earth’s crust, mantle, and core including temperature, density, and composition.. Estimating age in the archaeological record is the primary focus of archaeological sciences. Being able to establish a timescale is what sets archaeologists apart from other disciplines. . However. , relative dating techniques are still fundamental to the discipline.. Deformation. - the process by which the shape of a rock changes because of stress is called deformation.. compression. : stress that occurs when forces act to squeeze an object at a convergent boundary..
