There are a few ways. First they use uranium 235 to date the oldest rocks. U 235 is radioactive so it has a half life that can be meaured.

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.
Which correctly lists the three elements that geologists measure to determine the age of an organism’s remains?
carbon-12, potassium, and argon
How old do geologists think the earth is?
Geologists and other related Earth scientists have estimated the age of the Earth to be approximately 4.65 Billion years old based on a wide variety of scientific experiments and data.
How do fossils help geologists?
Fossils help geologists discover new species. Fossils also explain and show the age of the specimen and change in life forms.
What is the principle that helps geologists determine the age of rocks that are separated by distance?
original horizontality
Why do geologists study meteorites?
they are helpful to knowing the orgins, composition, and the age of earth From cahlil mizell

To determine the most accurate and precise age of the earths oldest rocks What would geologists use?
They would use absolute dating techniques which rely on the decay of radioactive isotopes found in association with the rock.
If approximately how old is the earth?
Modern geologists and geophysicists consider the age of the Earth to be around 4.54 billion years old. This age has been determined by radiometric age dating of meteorite material and is consistent with the ages of the oldest-known terrestrial and lunar samples.
What is the exact age f the earth right now?
No one can tell you exactly of course. But modern geologists and geophysicists consider the age of the Earth to be around 4.54 billion years old. This age has been determined by radiometric age dating of meteorite material and is consistent with the ages of the oldest-known terrestrial and lunar samples.
Why are index useful to geologists?
they tell the absoute age of rcoks which they occur
How does a geologist determine absolute age?
Geologists determine absolute age of rocks by using radioactive dating.
What is the study of the Earth's age?
The study of the Earth's age is known as geochronology. Geochronologists use various methods, such as radiometric dating of rocks and minerals, to determine the age of the Earth and the events that have occurred throughout its history. This field of study helps us understand the Earth's past and how it has evolved over billions of years.
How do scientists know that the earth has evolved?
From the history that is revealed in rock, particularly in fossils and the age of rock as determined by very precise radiometric dating techniques.
Geologists determine the absolute age of rocks using?
Geologists determine the absolute age of rocks using radiometric dating techniques, such as carbon dating or uranium-lead dating. These methods rely on measuring the proportions of radioactive isotopes and their decay products in the rocks to calculate how long ago they formed.
