We'll even visit the Grand Canyon to solve the mystery of the Great Unconformity!

Imagine that you're a geologist, studying the amazing rock formations of the Grand Canyon.

Relative dating is the science of determining the relative order of past events (i.e., the age of an object in comparison to another), without necessarily determining their absolute age, (i.e. In geology, rock or superficial deposits, fossils and lithologies can be used to correlate one stratigraphic column with another.

Prior to the discovery of radiometric dating in the early 20th century, which provided a means of absolute dating, archaeologists and geologists used relative dating to determine ages of materials.

Your goal is to study the smooth, parallel layers of rock to learn how the land built up over geologic time.

These strata make up much of the famous prominent rock formations in widely spaced protected areas such as Capitol Reef National Park and Canyonlands National Park.Throughout the history of life, different organisms have appeared, flourished and become extinct.Many of these organisms have left their remains as fossils in sedimentary rocks.Though relative dating can only determine the sequential order in which a series of events occurred, not when they occurred, it remains a useful technique.Relative dating by biostratigraphy is the preferred method in paleontology and is, in some respects, more accurate.
