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.

What two types of ages of rocks that geologists talk about?
Geologists talk about relative ages and absolute ages of rocks. Relative ages are determined by the order of rock layers, with younger layers on top and older layers at the bottom. Absolute ages are determined through radiometric dating methods to provide a specific age in years for a rock sample.
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.
Can geologists use radioactive dating to find the absolute ages of sedimentary layer A B C D and E?
yes because its a rock
Why is it difficult to determine the absolute age of a rock?
It is difficult to determine the absolute age of a sedimentary rock because sedimentary rocks are made up of diverse particles that are all different ages. As a result radioactive dating can only determine the age of the particles, not the whole rock.
Geologists would used qualitative measurement to?
- to determine the chemical nature of a rock - to determine the age of a rock by comparison
The number of years since a rock formed?
To determine the age of a rock, geologists typically use radiometric dating techniques that analyze the decay of radioactive isotopes within the rock. By comparing the ratio of parent to daughter isotopes present in the rock, scientists can calculate its approximate age. Different isotopes have different half-lives, which allow for dating rocks of varying ages.
What is the principle that helps geologists determine the age of rocks that are separated by distance?
The principle of relative dating helps geologists determine the age of rocks that are separated by distance. This principle states that in an undisturbed sequence of rock layers, the youngest rocks are at the top and the oldest rocks are at the bottom. By comparing the relative positions of rock layers in different locations, geologists can infer the relative ages of the rocks.
What clues does extrusion tell geologists?
Geologists study where intrusion and extrusion formed in relation to other rock layers. This helps geologists understand the relative ages of the different types of rock! Hope it helps;)😊
