Does radioactive dating tell the relative age of rocks?
No. Radioactive dating is an absolute dating tool.
How is earths geolgic history determined?
it is determined by studying the relative and absolute ages of rocks and fossils
What does relative dating provides?
It provides how old a rock/fossil is compares to the rocks/fossils around them.
How does the law of superposition help determine the relative age of rocks?
Radiometric dating can give us the absolute age of the rock. Trace fossils and the Law of Superposition can only provide the relative age of the rock. Radiometric dating is far more specific in formation analysis.
How do scientist use radioactive elements to determine the actual age of fossils?
scientist can determine a fossil's age in two ways: relative dating and absolute dating
What is examined to do relative dating?
The position of fossils in sedimentary rock layers.
Can fossils be used to determine the relative ages of rocks layers?
fossils can be used to determine the relative age of rock layer by using the classification of fossils to find the relative ages of rocks in which fossils are found. :] hoped i helped you out.
Do index fossils tell the relative or absolute age of fossils?
Index fossils can be used to help determine the relative age of rock layers. Index fossils are from species that only existed for a short time. Index fossils are found in rock layers. Trilobites and Graptolites are index fossils.
What two methods are used to determine the age of a rock?
The two methods are relative dating and radioactive dating for fossils. I think it's the same for rocks.
To determine the absolute age of rocks and fossils geologists use?
They would look for evidence of index fossils, those of certain rapidly evolving creatures that lived during a specific time period. This method is called relative dating. For a closer estimation they would be able to date the rock using radiometric techniques that base its age on the degree of isotope decay . This method would reveal the much more specific absolute age.
What fossils are useful in determining the relative age of rocks?
Index fossils
What do scientists use to date exact age of fossils?
For relatively recent fossils, dating by carbon 14 is the most accurate method. For older fossils it is necessary to analyse the geological layer in which they are found; fossils located in an undisturbed geological layer of a certain age, are the same age as the layer in which they are found, necessarily.
