Rocks are to geologists as stars are to astronomers.

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.
Geologists use fossils to determine the age of rocks through a process called biostratigraphy. They identify the specific group of fossils present in the rock layer, known as index fossils, that have a known age range. By comparing the index fossils to a geological time scale, geologists can estimate the age of the rock layer.
Geologists can't use rocks from Earth to determine the planet's age because those rocks have all been recycled through the rock cycle over time. This means that the original rocks from when Earth formed no longer exist. Instead, geologists use radiometric dating of rocks from Earth's surface to estimate its age.
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.
Rocks are to geologists as stars are to astronomers.
Geologists don't use rocks, they study them.
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.
That area has few plate forms around it.

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.
Geologists can measure the abundance of certain radioactive isotopes, such as carbon-14 or uranium-lead, in a specimen to calculate its age. By comparing the ratio of parent isotopes to daughter isotopes in a sample, geologists can determine the age of rocks, fossils, or other geological specimens. This process is known as radiometric dating.
