Chronological Analysis of the Scriptures- Literal interpretation of the scriptures led some people to conclude that the Earth was created approximately 6,000 years old.In fact, Archbishop Usher of Ireland calculated that the Earth was created at 9 AM on It was believed that prior to the Great Flood, Earths surface was flat and its climate was mild.Mountains, erosion, and variations in climate were considered to be punishment for the sins committed by humanity.Buffon's Iron Sphere Experiments- On the basis of iron sphere cooling experiments, Frenchman Georges de Buffon estimated that the Earth would have needed 75,000 years to cool to its present temperature.Sedimentary rocks- Sedimentary rocks are generally not datable using isotopic methods because the grains in sedimentary rocks may come from many different rocks of different ages.Isotopic age dating would not give the age of the sediment deposition or lithification, but rather the age of the source rocks.

Absolute dating methods are used to determine an actual date in years for the age of an object.Dating techniques are procedures used by scientists to determine the age of an object or a series of events.The two main types of dating methods are relative and absolute.Different isotopes of an element have similar chemical properties (undergo similar chemical reactions) but have different physical properties (such as evaporation rates).However, we can predict what fraction of the parent atoms will decay over a certain amount of time because each radioactive isotope has a constant rate of decay (unaffected by temperature, pressure, or chemical state).
