The reason why I bring this up is someone on here mentioned radiometric dating as evidence that the earth is billions of years old and five people gave that an answer a thumbs down.
I heard of stereotypes of people thinking the earth is much younger, but I was surprised that there appeared to be that many (relatively speaking) that did not believe that area of science is accurate.

1. radioactive elements decay at the constant and measurable rate?
2. all radioactive elements used for dating purposes have the same decay rate?
3. elements used for radiometric dating have both radioactive and non-radioactive isotopes?
4. non- radioactive isotopes decay at the same rate as radioactive isotopes?
please help me i need this

Half Life is when half of a sample of an isotope decays. This is what Carbon 14 dating is based on. When an animal or human dies, they always have the same amount of carbon 14 in them. After 5,700 years carbon 14 turns into Nitrogen 14. This is supposedly how they date biological animals and stuff. Q1. If all carbon 14 decays at the same rate, then why does only half of a sample decay in 5,700 years? Q2. If carbon 14 decays at differing rates, how is it possible to accurately date artifacts? Q3. If a single carbon 14 atoms transformation rate cant be figured out, how can we be completely sure our dating is accurate?

What is the best form of radiometric dating and why? I’m interested in knowing the science behind how we know it can determine the age of something. Thanks!

Can radiometric dating be used to find the absolute age of any material?
List some characteristics that would make some materials unsuitable for this dating method.

In radiometric dating, scientists use the rate of decay of radioactive materials in rocks to estimate the absolute age of a rock. That tells them the age of fossils found in that rock.
Radiometric dating allows scientists to find fossils in only the lowest and oldest layers of sediment.
In radiometric dating, scientists place samples of a fossil in certain liquids until the samples dissolve. The rate at which they dissolve indicates the age of the fossil.
In radiometric dating, scientists mix the carbon in a fossil with carbon from similar fossils whose age they know. By comparing, the carbon they can tell the exact age of the fossil.
