Why should you be careful when you find a fossil?
You should handle a fossil with care because they are very old and delicate.
Is it impossible to date a fossil with any certainty?
Well, it depends on how much detail you want. Carbon-dating is actually very accurate to within a few thousand years. This sounds like a long time to us, but when you are talking about a fossil that is millions of years old, a few thousand years is nothing. Of course, you can't say that a fossil has been in the ground since 1:27pm, Monday 5th June, 34,050,389 BC, but considering the time scales involved, we can date fossils pretty accurately.
How do you identify a index fossil?
By using relative age. Over a long period of time, sediment will, layer by layer, coat and cover the fossil, making it difficult for paleontologists and scientists to figure out how old the fossil really is.
How do scientists use Carbon-14 to date fossils?
Carbon-14 is in all living things and decays after it dies. It has a long half life (the time it takes for half a sample to decay into another element) and gives a good estimate as to how old something is. Carbon dating is only effective up to an approximate age of 70,000 years, and is only useful in dating organic matter. Since the vast majority of fossils are much older than this, carbon dating is not particularly useful in dating fossils, but is of great use in archaeology.
Why is the process of dating fossils often an example of circular reasoning?
I don't know how you arrived at that conclusion. But let say you're correct and there are some scientist that resort to circular reasoning; the finding will surely be debunked by other scientist and the original scientist will surely be disgraced. This is what separate evolution from creation; Creation is based on the supernatural and the faithful should believe the inerrancy of the Bible no matter what.
What is better for dating a sample about 1 million years old uranium-235 or thorium-232?
Thorium-232.
Would you use uranium 235 or thorium 232 to date a sample that was about million years old?
Uranium dating is recommended. Thorium dating (but with the isotope 230Th, not with the isotope 232Th) is recommended to minerals old of up to 500 000 years.
If I wanted to know how old a fossil was which type of dating would I be using?
Radiometric is the type of dating used to determine how old a fossil is.
How do scientist determine the relative age age of a rock or fossil?
Through geological dating and stratigraphy. Also, they use Uranium Dating. By measuring the amount of Uranium contained within the specific rock/fossil. Uranium-238's Half-Life is about 4.47 billion years, So each 4.47 billion years, the amount of Uranium is reduced by half. If the accepted amount of Uranium for a time period is 25%, and the sample contains 12.5%, then it is twice as old as that time period. Scientists cannot use carbon dating on rocks because they were never living things, and did not inhale carbon-14 from the atmosphere.
What isotope is best for dating very old rocks?
Uranium
How do you tell how old a fossil is by the rock layer?
by relative dating or radiometric dating
Why should you mine uranium?
Uranium is very useful for radioactive dating. It can date extremely old substances, and can date very accurately.
What are benefits of using uranium in dating the age of objects?
It is applicable to dating geological samples old from 104 to 2.106 years.
What are three types of radiometric dating?
These are three ways to find out how old a rock is. There's radiocarbon dating, potassium-argon dating and uranium-lead dating. Does this help?
How is uranium 235 used to date objects?
Uranium-235 dating, also known as radiometric dating, is used to determine the age of rocks and minerals on Earth. The technique relies on measuring the amount of uranium-235 and its decay product, lead-207, in a sample. By comparing the ratio of these isotopes, scientists can calculate the age of the material, providing insights into its geological history.
What determines the absolute age of rocks?
Radioactive dating. By measuring the amount of Uranium contained within the specific rock/fossil. Uranium-238's Half-Life is about 4.47 billion years, So each 4.47 billion years, the amount of Uranium is reduced by half. If the accepted amount of Uranium for a time period is 25%, and the sample contains 12.5%, then it is twice as old as that time period. Scientists cannot use carbon dating on rocks because they were never living things, and did not inhale carbon-14 from the atmosphere.
Why do geologists use uranium 235?
They don't. Carbon-14 has a short half-life and is normally only used by archaeologists or anyone working on sediments less than 50,000 years old. It becomes much less accurate after 40,000 years. Scientists used many different isotopes for dating rocks in Radiometric Dating, uranium/lead, potassium/argon and others are used. The half-life in some of these isotopes is measured in millions or billions of years.
