The age of the Earth is approximately 4.54 ± 0.05 billion years (4.54 × 10⁹ years ± 1%). This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial and lunar samples.

Radiometric dating is a method used to date rocks and other objects based on the known decay rate ofradioactive isotopes. The decay rate is referring toradioactive decay, which is the process by which an unstable atomic nucleus loses energy by releasing radiation.

a method of dating geological or archeological specimens by determining the relative proportions of particular radioactive isotopes present in a sample.

the time taken for the radioactivity of a specified isotope to fall to half its original value.

The history of Earth concerns the development of planet Earth from its formation to the present day. Nearly all branches of natural science have contributed to the understanding of the main events of Earth's past. ... Earthformed around 4.54 billion years ago by accretion from the solar nebula.

A fossil is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, hair, petrified wood, oil, coal, and DNA remnants.

The Rock Cycle is a group of changes. Igneous rock can change into sedimentary rock or into metamorphic rock. Sedimentary rock can change into metamorphic rock or into igneous rock. Metamorphic rock can change into igneous or sedimentary rock. Igneous rock forms when magma cools and makes crystals.

In geology and related fields, a stratum is a layer of sedimentary rock or soil, or igneous rock that were formed at the earth's surface, with internally consistent characteristics that distinguish it from other layers.

The geologic time scale is a system of chronological dating that relates geological strata to time.
