Age of Earth - Essay ExampleOne of these planets, the Earth, used to be a scorching molten rock that cooled into dry land for 70,000 historic period the period indicating how old the Earth was at the time Buffon made the study.On the other hand, Irish Archbishop James doorkeeper of the 17th century believed that the dates in the Bible are significantly reli fitted in determining how long the Earth has existed since creation. According to him, secular dates are able to project a trustworthy chronological structure of history where through the Bible, with specific reference to the death of King Nebuchadnezzar, he managed to estimate that the Earth was created on the 23rd of October, 4004 BC.For William Thomson, a British scientist widely known as Lord Kelvin, laws of thermodynamics govern the determination of the birth of the living planet. In particular, he necessitated the application of Fouriers theory to calculate a date when the Earth, initially in its molten state (7000 F), un derwent cooling via conduction and radiation. Upon solving the Fouriers equation, Thomson discovered the possibility that it could have got taken the Earth about 24-40 million years to form as the extreme level of temperature evened out in the process.By the time John Joly proposed the radical sodium method of approximating the Earths life during the late 19th century, he conducted a mathematical analysis of the rate at which salt is delivered to the oceanic waters. This involved finding the concentrations of salt (by mass) in all oceans from which Joly conveyed the notion that the sum of these concentrations (in grams) divided by the average rate of salt flow (in grams / year) into the ocean equals the do age of the oceans combined which then serves as the basis for the age of the Earth. The technique with sodium enabled Joly to conclude that the Earth is approximately 90 100 million years old.A more modern approach in the field of chemistry was employed by the
