How does a geologist determine absolute age?
Geologists determine absolute age by using radiometric dating techniques that involve measuring the decay of radioactive isotopes in rocks or minerals. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, geologists can calculate the absolute age of the rock formation. This method provides a numerical age in years for the rock layer or mineral.
IS stratigraphy is a method to determine the relative age of rock strata?
Yes, stratigraphy is a method used to determine the relative age of rock strata by studying the layers or strata of rock and determining their relative ages based on principles of superposition and original horizontality. This method helps geologists understand the sequence of events that have occurred in a particular area over time.
When geologists place rocks in their proper sequence of formation this is called dating?
No, when geologists place rocks in their proper sequence of formation, it is called relative dating. This method does not give an exact age, but it establishes the order in which rocks formed based on their position in a sequence. Absolute dating techniques are used to determine a specific numerical age of a rock or fossil.
When radiometric dating is done on a rock sample the rocks what is determined?
Radiometric dating measures the decay of radioactive isotopes within a rock sample to determine its age. By analyzing the ratio of parent isotopes to daughter products, scientists can calculate how long it has been since the rock formed. This method provides an absolute age, allowing geologists to construct timelines of geological events and understand the history of the Earth.
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.

How are index fossils used by uniformitarian geologists?
Uniformitarian geologists will use this method to determine which layer of rock formed at which time period of earth's history, and the order of the formation.
Can geologists use radioactive dating to find the absolute ages of extrusion and intrusion?
Yes, geologists can use radioactive dating to determine the absolute ages of extrusion (e.g., volcanic rock deposited on the Earth's surface) and intrusion (e.g., molten rock that has moved into existing rock formations). By analyzing the decay of radioactive isotopes within the rocks, geologists can calculate the age of these geological events.
Geologists would used qualitative measurement to?
- to determine the chemical nature of a rock - to determine the age of a rock by comparison

This method helps geologists understand the sequence of events that have occurred in a particular area over time.
What is the s and p time method in science?
The S-time method in science is a technique for determining the relative ages of rock layers by observing the sequence in which they were formed. The P-time method involves using radiometric dating to determine the absolute age of rocks based on the decay of radioactive isotopes. Together, these methods help geologists understand the chronology of Earth's history.

No, when geologists place rocks in their proper sequence of formation, it is called relative dating. This method does not give an exact age, but it establishes the order in which rocks formed based on their position in a sequence. Absolute dating techniques are used to determine a specific numerical age of a rock or fossil.
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.
Is relative dating the most accurate process by which geologists determine the age of a rock?
No. Absolute dating is the most precise method for dating rock. Absolute dating relies on the known rate of decay of radioactive elements present in the rock to arrive at a fairly precise age.
What is the fossil called that geologists use to determine rock ages?
Index Fossil
