The earth is a dynamic system and it is constantly changing, even when we can t see those changes on a daily basis.     law of cross-cutting if a rock layer is cut by a fault or igneous intrusion, the rock that is cut must be older than the layer that cuts it. Then, watch the video lesson to learn more. One method is absolute dating, which uses the half-life of radioactive isotopes to date the age of each rock sample.     law of lateral continuity rock layers will extend outwards until the environment that produced them changes relative rock dating worksheet.     law of original horizontality layers of sediment, such as you would have in the bottom of a lake, or the ocean, are deposited by gravity into flat layers. Finally, apply what you learned in the activity and practice sections.

  these techniques were first articulated by nicolas steno, a dane living in the medici court of italy in the 17th c.   his four observations on relative age relationships have been coined “steno’s laws” and are fundamental to the study of rock strata, or stratigraphy. Imagine climbing a trail from the top of the canyon down to its base. Geologists use a collection of guiding principles when determining relative sequencing of geological formations. A second method is relative dating, which places the order of geologic events by comparing rock layer positions without setting a specific time of formation. Perhaps you have seen it in photographs or videos. Although each principle may make common sense, using them together to unravel the history of ancient rock formations can prove very complex.

 relative relative dating (steno s laws):     long before geologists tried to quantify the age of the earth they developed techniques to determine which geologic events preceded another, what are termed relative age” relationships.

Geologists work to piece together the story and timeline of these changes using a combination of methods. .
