What do geologists use to determine the relative ages of a rock?
Relative dating refers to the process of determining the age of a rock, feature, or fossil by comparing it to the rocks around it. To use relative dating, you need to look at the order each rock layer was deposited.
What are two methods geologist use to determine the age of a rock?
Geologists use relative dating methods to determine the sequence of events that led to the formation of rocks by analyzing the layering of rocks. They also use absolute dating methods such as radiometric dating to determine the numerical age of rocks by measuring the decay of radioactive isotopes within them.
What do Geologists use radiometric dating to date sedimentary rock?
Geologists use radiometric dating of volcanic ash layers within sedimentary rock to determine the age of the sedimentary rock. By dating the igneous rock layers above and below the sedimentary rock, geologists can establish a bracket of time within which the sedimentary rock was deposited.
What is the technique in which natural laws govern the way geologists determine the age of rock deposits?
Geologists use the technique of radiometric dating to determine the age of rock deposits. This method relies on the natural decay of radioactive isotopes within the rocks to calculate their age based on the ratio of parent isotopes to daughter isotopes present in the sample.
What test do geologists use to discover the age of a fossil?
Geologists often use relative dating. When a fossil is found in a rock layer that has been dated, they know the age. If the fossil is found between two dated rock layers, they have an approximate age. If it's found above a dated layer, than it's younger, and vice versa. To date a layer of rock, radiometric dating is used. This measures the trace amount of a radioactive isotope, such as a uranium isotope or potassium isotope, which is then compared to its decay product, lead or argon, respectively, for these examples. More decay product and less of the original isotope means the layer is older, and vice versa. Index fossils can also be used. These are common fossils with a wide distribution that only existed for a short time. Then, when these are found in a rock layer, it is known that the rock layer formed when that organism existed.
Do geologists use the relative dating method on earth?
Yes, Geologists use the relative dating metod on earth.

Can geologists use radioactive dating to find the absolute ages of the extrusion?
yes
Which substances do geologists use in radiocarbon dating?
Carbon 14 and carbon 12
Do geologists use nuclear?
Nuclear explosives, no! Nuclear dating methods, yes.

How can you use fossils and geologic-features interpret the relative age of rock layer?
Geologists use carbon-14 to interpret the relative age of rock layers
Can geologists use radioactive dating to find the absolute ages of extrusion or the intrusion?
yes they can they did it with aborinies
What do scientists use to determine a fossil's relative age?
Carbon14 dating (isotopic dating)
When do scientists use both radioactive dating and relative dating to find the age of a rock?
Skonka!
