Problems with relative dating techniques

The most common form of relative dating is called stratigraphic succession.This is just a fancy term for the way rock layers are built up and changed by geologic processes.

In this method, scientists compare different layers of rock to determine an ordered sequence of events in geologic history.In 1896, a French physicist named Henri Becquerel discovered radioactivity in an element called uranium.He saw that it underwent radioactive decay, or emission of energetic particles to produce new elements.Scientists are always spouting information about the ages of rocks and fossils. Well, they figure it out using two different methods: relative dating and numerical dating.Let's find out more about these geological dating methods in order to understand how Paul the Paleontologist can be so sure about the age of his dinosaur fossils.Again, this doesn't tell them exactly how old the layers are, but it does give them an idea of the ordered sequence of events that occurred over the history of that geologic formation.Sort of an offshoot of stratigraphic succession is fossil succession, or a method in which scientists compare fossils in different rock strata to determine the relative ages of each.Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.Consider the following scenario: Paul the Paleontologist is a very famous scientist who has studied dinosaur bones all over the world.In 1905, Ernest Rutherford figured out that we could use radiation to establish the ages of rocks.By studying how the mass of uranium changed with radioactive decay, Rutherford was able to determine the age of a rock containing a uranium mineral. It meant that scientists could suddenly establish the actual ages of all their rocks and fossils!


  1. Aug 2, 2014. This technique has posed a different problem for creationists, as this dating method does not make use directly of accelerated decay. By using dendrochronology scientists have dated certain living trees to having ages of around 4600 years. This finding showed the current model for carbon-14 dating to be.

  2. Our planet Earth consists of numerous rocks and formations. Archeologists, geologists, and anthropologists primarily make use of relative dating techniques to understand the sequence of events, in order to establish the facts such as the time period of formation of planet Earth.

  3. Learn how scientists determine the ages of rocks and fossils. We'll explore both relative and numerical dating on our quest to understand the process of geological dating. Along the way, we'll learn how stratigraphic succession and radioactive decay contribute to the work of paleontologists.

  4. Mar 10, 2018. With the accession of the new king the troubles began which ended in the disruption of the empire. Relative dating. Dates expressed relative to one another. Geological principle that in any pile of sedimentary rocks that examples of relative dating methods have not been disturbed by folding or overturning.

  5. Goals To define and distinguish between relative and radiometric methods of dating. To understand the types of dating information provided by the relative positions of geological strata. To apply principles of radioactive decay and Steno's Laws to problems about the age of organisms. To understand how information.

  6. Accuracy of dating. Dating in geology may be relative or absolute. Relative dating is done by observing fossils, as described above, and recording which fossil is younger, which is older. The discovery of means for absolute dating in the early 1900s was a huge advance. The methods are all based on radioactive decay.
