Scientists study rocks that, in most cases, are millions of years old.

Radiocarbon dating (radioactive dating) uses the break down of carbon to determine how old the rock is.

Half-life is the amount of time it takes for half of the parent isotopes to decay. In another 5,730 years, the organism will lose another half of the remaining C-14 isotopes.

This process continues over time, with the organism losing half of the remaining C-14 isotopes each 5,730 years.

The oldest date that can be accurately found using carbon dating is around 10,000 years so they would not be able to date a million year old rock. Relative dating can be done in many different ways.

Looking at the layers of sediment deposition and counting fossil tree rings in rock formations are just a few ways.

All ordinary matter is made up of combinations of chemical elements, each with its own atomic number, indicating the number of protons in the atomic nucleus.

Scientists find the ratio of parent isotope to daughter isotope.Radiometric dating is also used to date archaeological materials, including ancient artifacts.Different methods of radiometric dating vary in the timescale over which they are accurate and the materials to which they can be applied.The biggest assumption is that, to first order, the number of asteroids and comets hitting the Earth and the Moon was the same as for Mercury, Venus, and Mars. The bottom line is that the more craters one sees, the older the surface is.This can be interpreted in two ways: why it is important to know the age of a planet or how is age dating important in determining the age of a planet?For EXAMPLE: The top most level of sediment is younger than the level below it and the dike was intruded before the younger level, but after the oldest layer, that means the dike is older than the top level.
