They use a method called Carbon Dating, which allows them to get a really precise measurement on when the rock, or fossil (usually a fossil is what they Carbon Date) was either made or destroyed. (though even when destroyed, a sample can still easily tell them what time it was from.)
Geologists determine the age of rocks through a process called radiocarbon dating, a process which "peers inside [the] atoms" of the rocks. For more detailed information about how radiocarbon dating works, check out the related link which is a website with lab instructions for groups in a class.

Paleontologists use fossils to determine the relative ages of rocks. Due to evolution the fossil assemblage in rocks changes over time and the different assemblages can therfore be used to place the rocks in which an assemblage is found in its place in the evolutionary sequence.
The actual age of a rock can be determined through radiometric dating methods that analyze the decay of radioactive elements within the rock. By measuring the ratio of parent isotopes to daughter isotopes, scientists can calculate the rock's age in years.
Isotopes can be used to determine the age of a rock through radiometric dating, but they do not determine the size of the rock. By measuring the ratio of parent and daughter isotopes in a rock sample, scientists can calculate its age based on the rate of radioactive decay.

The most effective way for a scientist to determine the actual age of a rock is through radiometric dating methods, such as carbon-14 dating or uranium-lead dating. By measuring the decay of radioactive isotopes in the rock, scientists can calculate its age with high precision.

Paleontologists, stratigraphers, and geochronologists worked with geologists to develop the geologic time scale. Paleontologists studied fossil evidence, stratigraphers looked at the layers of rock formations, and geochronologists used radiometric dating techniques to determine the age of rocks and fossils.

Paleontologists, stratigraphers, and geophysicists collaborated with geologists to develop the geologic time scale. Paleontologists studied fossils to identify and date rock layers, stratigraphers analyzed the layering and deposition of rocks, and geophysicists used techniques like radiometric dating to determine the age of rocks.

Paleontologists, stratigraphers, and geochronologists worked with geologists to develop the geologic time scale. Paleontologists study fossilized remains of ancient life forms, stratigraphers study rock layers and their relationships, and geochronologists use various dating techniques to determine the age of rocks and events in Earth's history.

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.
