Uranium dating is not better but is used for long times in geology; carbon 14 is used for short times in Archaeology.

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.


Why is natural gas better than uranium?

Each fuel has advantages and disadvantages; methane gas will be exhausted in the next 60 years (probably) and the price is increasing. Also methane gas release carbon dioxide during burning.


What is the difference between a carbon atom and a uranium atom?

I won't even waste the time looking up actual numbers.a mole of atoms of helium is about 4 grams, therefor 1 gram of helium is about 0.25 moles of helium atomsa mole of atoms of uranium is about 238 grams, therefor 1 gram of uranium is about 0.0042 moles of uranium atomsA gram of helium contains more atoms than a gram of uranium by about a factor of 60.


How does carbon dating prove a young earth?

Carbon-dating can not be used to prove the age of the earth, so it can not be used either to prove a "young earth" nor to support the scientific age of the earth. Carbon-dating is useful for archaeology, where it can date evidence of human artefacts up to fifty thousand years old. Some less less informed "Young Earth" creationists do believe that carbon-dating was used to date the earth. They attempt, unsuccessfully, to undermine the science of carbon-dating in the belief that by doing so they undermine the scientific age of the earth, rather than because they constructively prove their point. The best estimates of the age of the earth have been arrived at by radioactive dating, but not by carbon-dating. Had techniques of radioactive dating not been invented, other known methods of dating the earth would prove that the world is more than a few million years old. Some of these are described in the related question, attached below.


What is true of a radioisotope that is used to date rock formations?

There are a number of such isotopes.Geological dating requires isotopes with longer half lives than carbon-14 has. It also requires other things, such as that the elements involved do not wash away in water or escape as gas in an unknown manner.What is usually done is a comparison of the amount of a radioactive element with the amount of the element it decays into. so geological dating is usually done by looking for pairs of elements bound in the rocks. These pairs include:samarium-147 and neodymium-143potassium-40 and argon-40rubidium-87 and strontium-87uranium-234 and thorium-240There is also a dating technique in which tracks markings left by spontaneous fission of uranium are analyzed to compare quantities of uranium-235 and uranium-238.A link to a Wikipedia article on radiometric dating is given below.

Why is a uranium isotope often used rather than 14C in radiometric dating to determine the age of earth?

The isotope carbon 14 is used only for organic materials (or objects contaminated with organic materials); also carbon 14 dating is applicable only to short periods of time.

How does carbon dating or radioactive dating work and why is it used?

Everything has carbon in it. When the organism dies, it begins to disintegrate. We know the rate at which things disintegrate at, so we can determine how much carbon is left and then apply a scientific formula and figure out how old the organism is. Radioactive dating works much the same.

Is casual dating better than a dating web site?

Yeah, of course I think casual dating is better than a dating website. You will be able to see the person you are dating and be with the person and you could be able to decide whether the person is of your type.


Carbon 14 is useful for dating fossils that are?

Carbon 14 dating is most useful for dating fossils that are up to 50,000 years old. Beyond this time frame, the amount of C-14 left in the fossil is too minimal to provide accurate dating results.

If carbon dating is inaccurate on marine animals how can you trust it for the marine animals in strata such as the Cambrian rock?

Perhaps you can't, but carbon dating is not used on mineralized fossils. The igneous rock above and below the fossil strata is radiometricly dated, Carbon dating is only good on material containing carbon; material less than 40,000 years old.
