Isotope dating fossils
Usually, atoms have an equal number of protons and neutrons.
C) dating usually want to know about the radiometric dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years.
People wonder how millions of years could be squeezed into the biblical account of history. Christians, by definition, take the statements of Jesus Christ seriously.
How do scientists know the bones are really 68 million years old?
Today's knowledge of fossil ages comes primarily from radiometric dating, also known as radioactive dating.
Only hard parts, like bones and teeth, can become fossils.
But for some people, the discovery raised a different question.
It wasn't until well into the 20th century that enough information had accumulated about the rate of radioactive decay that the age of rocks and fossils in number of years could be determined through radiometric age dating.
This activity on determining age of rocks and fossils is intended for 8th or 9th grade students.
When paleontologist Mary Schweitzer found soft tissue in a Tyrannosaurus rex fossil, her discovery raised an obvious question -- how the tissue could have survived so long?Tags: Adult Dating, affair dating, sex dating
