    1.The Law of Superposition – the age of an object may be determined by the depth at which it is found, the deeper the object is in the Earth, the older it is. 2.Gives scientist an exact age of a rock fossil. 3.Scientist use their knowledge of the half-life of carbon and uranium isotopes to measure the age of the rock or fossil . 4.Used to determine the age of an object, when there is no record of a living thing. 5.Gives the approximate age of a fossil or artifact. 6.Used by scientist to determine the age of a fossil or artifact. 7.Estimates the order of geological or prehistoric events, but cannot be used to determine when these events have occurred. 8.Measures the decay of a rock or fossil to measure the age.

    Relative dating means there is some relationship that points out older or younger. One example is if you have a rock that is covered in some lava flow. The rock is older than the lava because it was there to get covered! Then whatever covers the lava is even newer still. Absolute dating means using science to find a date that it more precise. As you can see from just those definitions, some things will apply to absolute dating that do not apply to relative.

    One of thse answers is going to depend on how accurate they see absolute dating as. Some, more basic, textbooks just say "absolute dating as accurate" and leave it at that. In real life, it is still an estimate due to lots of conditions... it is just a reasonable accurate estimate of a range of dates.

    Well, a living thing might mean a carbon date... carbon dating is one form of absolute dating... so I am doubting that one.

    1.The Law of Superposition – the age of an object may be determined by the depth at which it is found, the deeper the object is in the Earth, the older it is. That is like HALF of relative dating right there. The other half being about injections of magma and coverings of lava etc. So you can eliminate it.

    Absolute dating gives a date. How accurate depends on the isotope decay being measured.

    Now, since they are both dating methods, which answer is basically a giveaway because it only deals with dating?

    No, 8 is decay. Decay is the same as half life... so carbon 14, etc. absolute.

    "6.Used by scientist to determine the age of a fossil or artifact." Exactly! They both give some sort of age. Absolute is in years. Releatve is in older/younger or by eria like "Jurasic."

    The last part of that page: ___ Problems with dating Carbon dating is often the most accurate way of finding out the age of a recent fossil and the rock or other deposit it was found in. However, in old fossils, the proportion of Carbon-14 is so low that it is difficult or impossible to date them accurately. Carbon dating is not generally reliable for finds that are more than 40,000 years old, so other dating methods have to be used. Scientists try to avoid using a single sample of material to work out its age. Where possible, it is better to take several samples from the same layer and date them all, preferably using different dating methods, to get the most accurate result. ___ is why I think I know the other answer. It has to do with when "absolute" dating is not really that absolute.

    As for your last guess, #3 talka about half life and carbon, which only have to do with absolute datain. It might be easier to cross out the ones that have clear things for one or the other and see what is left.
