While the oldest known rocks on Earth are about 3.5 billion years old, researchers have found zircon crystals that are 4.3 billion years old [source: USGS].Based on the analysis of these samples, scientists estimate that the Earth itself is about 4.5 billion years old.Other techniques include analyzing amino acids and measuring changes in an object's magnetic field.Scientists have also made improvements to the standard radiometric measurements.

Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon.Each of them typically exists in igneous rock, or rock made from cooled magma.
