They take samples and experiment on them and look at the samples with microscopes. The experiments can then show them the age of the rock.
They say "how old are you mr rock" then the rock will say its ages

What else can I help you with?
How can the relative and absolute ages of rock be determined?
By comparing the relative percentages of a radioactive (parent) isotope and a stable (daughter) isotope.
Why do scientists call lava the newest rock on earth?
Scientists call lava the newest rock on earth because it hasn't even cooled into igneous rock yet, making it effectively 0 days old.
What is the process of calculating the absolute age of rock by measuring the amounts of parent and daughter materials in a rock and by knowing the half-life of the parent called?
radiometric dating
What characteristics determines the chemical composition of an igneous rock?
An igneous rock is any crystalline or glassy rock that forms from cooling of a magma. Color and texture help determine the chemical composition of the rock.
What is an index mineral?
An index mineral is used in geology to determine the degree of metamorphism a rock has experienced.
What method do geologists to determine the absolute age of a rock?
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
What method do geologists use to determined the absolute age of a rock?
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
Which dating method enables scientists to measure or estimate the absolute age of sedimentary rock?
Radiometric dating of igneous rocks that relate to the sedimentary rock
How did scientists determine the information about earth's crust?
By poking, prodding, analyzing rock, testing hypothesis. The scientific method.
How do scientists use to determine the age of a rock on the ocean floor?
Scientists use a method called radiometric dating to determine the age of rocks on the ocean floor. This technique involves measuring the proportions of certain radioactive isotopes and their decay products within the rock to calculate how long it has been since the rock formed. By analyzing these ratios, scientists can estimate the age of the rock.
What evidence would a scientists use to determine the absolute age of a fossil found in sedimentary rock?
The Igneous intrusions and extrusions near sedimentary layers.
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.
How scientist know the age of a rock?
Scientists use radiometric dating to determine the age of rocks by measuring the decay of radioactive isotopes in the rock. This method relies on the known rates of decay of specific isotopes to calculate the age of the rock. By analyzing the ratio of parent isotopes to daughter isotopes in a sample, scientists can accurately determine how long ago the rock formed.
Radioactive dating of rock samples is a method?
used to determine the age of rocks and minerals by measuring the abundance of certain radioactive isotopes within them. This method relies on the fact that radioactive isotopes decay at a known rate over time. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate how long it has been since the rock or mineral formed.
What do geologists use to determine the absolute ages of rock?
Radioactive dating is used to determine the absolute ages of rocks. By Jennifer Palos
How do scientist use Radioactive Isotopes to find the absolute age of a rock?
Scientists use radioactive isotopes in rocks to calculate their absolute age through a process called radiometric dating. By measuring the ratio of parent isotopes to daughter isotopes in a rock sample, scientists can determine how much time has passed since the rock formed. The rate of decay of the parent isotope into the daughter isotope provides a clock that allows scientists to calculate the rock's age.
Is it true that Stratigraphy is a method to determine the relative age of rock strata?
Yes, that is true. Stratigraphy is the study of rock layers (strata) and their relative positions in order to determine the sequence of events that created them. By analyzing the different layers and the fossils or artifacts found within them, scientists can establish the relative ages of the rock strata.
