Melissa graduated from NC State University with a Bachelor's Degree in geology in and currently works as a lab technician. Figuring out the geologic history of an area seems like a daunting task, but there are several strategies that geologists use to figure out which rocks are older than other rocks, and what geologic processes occurred in a particular order. Geologists can numerically date certain rocks by using the radioactive decay of elements trapped in rocks or minerals to figure out their exact age. However, these radioactive isotopes aren't always present in a rock, so geologists must use context clues to build a calendar called a geologic timescale of when each rock layer in a formation was created. Relative dating uses a series of 5 principles listed in the following paragraphs that help geologists compare the ages of different layers of rock and create a geologic timescale for an area. Most sediments that you see in rock formations are deposited in horizontal layers originally, due to the effect of gravity.

Home sedimentary Stratigraphy. In , Niels Stensen , better known then and now by his Latinized nameii Nicolaus Steno, formulated a few basic rules that helped him make sense of the rocks of Tuscany and the various objects contained within them. Three of these are known as Steno's principles, and a fourth observation, on crystals, is known as Steno's Law. In a sequence of strata, any stratum is younger than the sequence of strata on which it rests, and is older than the strata that rest upon it.

Our planet inherits a large number of artifacts and monuments bestowed upon us by older historic civilizations. These remains are subjected to dating techniques in order to predict their ages and trace their history. This ScienceStruck post enlists the differences between the absolute and relative dating methods. Although both relative and absolute dating methods are used to estimate the age of historical remains, the results produced by both these techniques for the same sample may be ambiguous.
