Feb 08,  · d - is incorrect because radiometric dating works just fine on rocks billions of years old, eg K/Ar. e - is incorrect because a perfectly errorless determination in science is a rare thing. If I had to pick the "best" answer out of those five possibilities I'd go with a, because it refers to "indirectly" and "surrounding layers.".

Sep 16,  · If there is a radioactive element we can use the decay rate and amount of daughter products to give an estimate of the age of the rock; provided we assume that we know the original proportions and the rock is a closed system.
Feb 01,  · I put this question on the wrong category, so you might see it twice.. Please answer this question(s) Imagine that to simulate radioactive dating you are popping a bag of popcorn in the microwave that contains exactly 80 unpopped kernels. The duration of a single half-life for popcorn is 30 seconds. Answer Questions: 1) In this situation, describe what would represent parent and daughter .
Oct 28,  · Radioisotope (also called radiometric) dating is based on the rate of decay of the elements in the rock from the original (parent) element to the resulting (daughter) element. This dating is based on assumptions such as: 1. The original condition of the rock; 2. The half life (rate of decay) has remained the same since the rock was formed; and 3.
Radiometric Dating? | Yahoo Answers Radiometric dating measures the decay of radioactive atoms to determine the age of a rock sample. It is founded on unprovable assumptions such as 1) there has been no contamination and 2) the decay rate has remained constant. Radiometric Dating | Answers in Genesis I put this question on the wrong category, so you might see it twice.. Please answer this .
Dec 14,  · What are some scientific reasons that radiometric dating of diabase sills would be less accurate than other dating methods such as potassium-argon, rubidium-strontium, etc? Some basic background information on the reliability of dating these sills, found in places such as grand canyon strata: Diabase sills are intrusive in relation to formed strata obviously indicating that it is younger than.

Jun 16,  · When scientists use radiometric dating to date the earth do they use a day year or do they take into account tidal friction(the leap second) so that it is based on the actual rotation of the earth's orbit around of the sun? For example, if the earth is billion years old then it would be billion times days if they didn't account for tidal friction.
Radiometric Dating Yahoo Answers LibGen is a unique concept in the category of eBooks, as this Russia based website is actually a search engine that helps you download books and articles related to science.
Jun 20,  · Radiometric dating is a technique used to date materials based the decay rates of naturally occurring isotopes. For example, radiocarbon dating is a method that uses the naturally occurring isotope carbon to determine the age of things like trees, which contain carbon.
Nov 13,  · Radiometric dating (often called radioactive dating) is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.

Jul 16,  · (A) Radiometric dating. Fossils themselves are not (usually) datable: it is the strata that the fossils are found in, or the strata above and/or below the strata the fossils are found in, that is dated. (B) Relative dating. Relative dataing cannot give a date without some strata having already been dated radiometrically or by some other means.
Aug 09,  · Yahoo Products; Anonymous. Anonymous If radiometric dating and carbon dating can be flawed. Are the ages of the planets just educated guesses? Answer Save. 13 Answers. Relevance. Andrew Smith. Lv 7. 2 years ago. They aren't guesses but they are based on assumptions. If the assumptions are not true then the ages would also be indeterminate.
Aug 22,  · It has been shown that the half-life for this radioactive isotope is 20 years. In the year , an archaeology team unearths pottery and is using this isotope for radiometric dating to place the age of the pottery. It is shown that 95% of the nuclei have decayed. How long ago was the pottery made?
Mar 01,  · If you haven't guessed I am home schooled. I have a big essay coming up soon, which basically asks to point out the weaknesses of the geologic column and how radiometric dating is grossly inaccurate. Now I want to instead help prove those two things, and hopefully put an end to the arguing, however I don't mind if it doesn't.
Mar 16,  · The Kinetics of Radioactive Decay and Radiometric Dating (help!!) nuclear equations? Write a series of nuclear equations to represent the bombardment of Al with a neutron to form a product that then undergoes an alpha decay followed by a beta decay.

May 06,  · Carbon would be undetectable after around 50, years. So the relative dating method is not on a very sound footing. In radiometric dating, scientists look at the ratios of naturally occuring radioactive isotopes (atoms that carry an electrical charge) found in igneous rocks.
Feb 05,  · So when it came to carbon dating, a scientist said 'Well how do we know what the levels of CO2 were like? We should try and find ways to figure that out and calibrate our dating methods to that'. So they did. So you accept one piece of radiometric evidence, and then say radiometric evidence is a farce. WHAT.

Dec 25,  · FYI, radiometric dating is not % accurate (dendrochronology is the most accurate form of dating in anthropology), but it is very close. Saying that radiometric dating is unreliable because it occasionally messes up is like saying that all cars are unreliable because some cars don't work. In other words, saying so is nonsense.
Jan 10,  · There are *lots* of other forms of radiometric dating besides Uranium-Lead dating. There is also Potassium-Argon dating, Uranium-Thorium dating, Rubidium-Strontium dating, etc. etc. Carbon dating is also a kind of radiometric dating, but is not very useful for rocks for two reasons.
Jul 30,  · Radiometric dating requires the presence of radioactive nuclides, such as elements like U, Th, Po, Rb, Sr, Re, Os, K, Ar, and many others. But rocks that contain fossils are usually composed mostly of elements like Si, Fe, Ca, and Al, which for the most part don't have any radioactive isotopes useful for radiometric dating.
Jun 29,  · Carbon dating and other forms of radiometric dating are incredibly accurate because an unstable molecule degrades at a specific half-life regardless of other factors. Carbon is good for a few thousand years but there are a lot of other elements that can be used too.
Apr 17,  · If such material can be found along side fossils, the fossil's age can be approximated to the age of the carbonaceous material. However, these proportions are discernible only to about 60, years ago using carbon isotopes, which is just one form of radiometric dating.
Feb 17,  · The age of Earth is estimated to be ± billion years ( × years ± 1%). This age may represent the age of the Earth's accretion, or core formation, or of the material from which the Earth formed. This dating is based on evidence from radiometric age-dating of meteorite.
Half Life [HOST] Life QUESTION 24 4 points Save Answer After collecting field samples you want to determine the age of two rock layers deposited in a canyan. The upper layer contains U% parent and the lower layer contains % parent.
