Radiometric dating problem


How radiometric dating works in general Why methods in general are inaccurate Why K-Ar dating is inaccurate The branching ratio problem How Errors Can Account for the Observed Dates Why older dates would be found lower in the geologic column especially for K-Ar dating Do different methods agree with each other on the geologic column?

After study and discussion of this question, I now believe that the claimed accuracy of radiometric dating methods is a result of a great misunderstanding of the data, and that the various methods hardly ever agree with each other, and often do not agree with the assumed ages of the rocks in which they are found. A scientist is radiometrically dating 3 different rocks. Which of the following is evidence supporting the theory that humans share a common ancestor with apes? Our DNA is over 99% similar to that of chimpanzees b. Which of the following is a true statement about human evolution? Bipedal posture and large brain size evolved at the same time. Try the problems out, then check your answer below. If an element has a half-life of twenty million years, and there is 6.25% of it remaining in a rock, how old is the rock? In a certain rock, there is 1/16th of the original parent element, and 15/16th of the daughter element. The only problem is that we only know the number of daughter atoms now present, and some of those may have been present prior to the start of our clock. The reason for this is that Rb has become distributed unequally through the Earth over time.
