SOLAR SYSTEM

Detailed explanation-1: -As advances in chemistry, geology, and physics continued, scientists found a method by which the absolute age-an actual number of years-of a rock or mineral sample could be determined. This method is called radiometric dating, and it involves the decay, or breakdown, of radioactive elements.

Detailed explanation-2: -Looking at moon rocks to determine the age of Earth Zircon crystals from Jack Hills in Western Australia, aged at 4.404 billion years, currently hold the record for the oldest mineral on Earth.

Detailed explanation-3: -Scientists have validated the estimated age of the Earth using Moon rocks, meteorites, and the isotopic compositions of lead in meteorites and ancient lead ores (Dalrymple 1991).

Detailed explanation-4: -This valuable method is called radiometric dating. Scientists used the proportion of parent material remaining to the proportion of daughter material produced in order to predict the age of the rock. During each half-life, only one-half of the parent material decays to the daughter product.

Detailed explanation-5: -An age of 4.55 ± 0.07 billion years, very close to today’s accepted age, was determined by Clair Cameron Patterson using uranium–lead isotope dating (specifically lead–lead dating) on several meteorites including the Canyon Diablo meteorite and published in 1956.
