Many of the largest mountain ranges and broadest zones of seismic activity come from collisions..

Comparisons of carbon ages with tree-ring data and other data for known events have allowed reliable calibration of the radiocarbon dating method.

This produces one of two different effects: 1) an electron jumps in to fill the missing spot of the departed electron and emits an X-ray, or 2) in what is called the Auger process, another electron is released and changes the atom into an An atom that has different number of neutrons but the same number of protons.

Working out Earth’s history depended on realizing some key principles of relative time.

is when an alpha particle, which consists of two protons and two neutrons, is emitted from the nucleus of an atom.

While most properties are based on the number of protons in an element, isotopes can have subtle changes between them, including temperature fractionation and radioactivity.

Modern applications of this method have achieved remarkable accuracies of plus or minus two million years in 2.5 billion years (that’s ±0.055%)U.

The existence of these two clocks in the same sample gives a cross-check between the two.

Many geological samples contain multiple parent/daughter pairs, so cross-checking the clocks confirms that radioisotopic dating is highly reliable.
