How are stratigraphic and radioactive dating different in regards to how they date fossils?

Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains. Relative dating, meanwhile, measures the order of past events, without determining their absolute age.


Why do scientist use radioisotopes to find the age of fossils?

Radiometric dating of fossils is not possible beyond roughly 70,000 years. However, when fossils are found in association with strata of volcanic and metamorphic rocks which can be dated radiometrically, a very accurate age of the fossils can be determined.


Carbon 14 is useful for dating fossils that are?

Carbon 14 is useful for dating organic remains less than 60-70,000 years old. It is not useful for fossils as the vast majority are much older than that.


How has radio metric dating made the construction and interpretation of the statigraphic record more reliable?

Radiometric dating has significantly enhanced the reliability of the stratigraphic record by providing precise numerical ages for rock layers and fossils, allowing geologists to establish a clear chronological framework. This method helps to correlate strata across different geographic locations, improving the understanding of Earth's history and the timing of geological events. Additionally, by integrating radiometric dates with biostratigraphy, scientists can create more accurate models of evolutionary timelines and major environmental changes. Overall, radiometric dating offers a robust tool for validating and refining the stratigraphic record.


How do we date events is earth's history?

Events in Earth's history are dated using a variety of methods, including radiometric dating of rocks and fossils, stratigraphic analysis of rock layers, and studying the patterns of biological evolution in the fossil record. By combining these different dating techniques, scientists can establish a timeline of events and understand the sequence in which they occurred on Earth.


What is the name of the fossils that are widespread geographically and are limited to a short span of geologic time?

Index Fossils. They are very important tools for geologists and used in paleontology and stratigraphic studies.


What are the flaws of evolution?

Yes. There are many flaws like carbon dating. It is only accurate for thousands of years not millions. Also fossils don't prove evolution because we don't know if these fossils had babies or not. Fossils don't come with tags to explain itself.


How does the age of fossils found in seafloor?

Fossils found on the seafloor can be dated using techniques such as radiometric dating or stratigraphic correlation. By analyzing the rock layers and the types of fossils found in them, scientists can determine the age of the fossils and the seafloor where they were discovered. This helps in understanding the history of the ocean and the evolution of marine life.


What is the connection between fossils and half-life dating?

The connection between fossils and half- life dating is that half-life dating is to determined how old the fossil is


What is the Specific age of a rock or fossil?

The specific age of a rock or fossil can be determined through radiometric dating techniques, such as carbon dating or uranium-lead dating. These methods measure the amount of radioactive isotopes present in the sample to calculate its age. Additionally, stratigraphic dating can be used to determine the relative age of rocks and fossils based on their position in layers of sedimentary rock.


What controversy exists in using radioactive dating?

Not everyone believes that radioactive dating is accurate. There are people out there who don't believe the earth is older then 10,000 years old claiming that there is no way that dinosaur fossils can be as old as they say they are.
