Answer from: tiffanydowell13

I will!

Explanation:

to determine the related age of different rocks geologists start with the assumption that unless something has happened in the sequence of sedimentary rock layers the newer Rock layers will be on top of the older ones this is called the rule of superposition with absolute age dating you get a real age and actual years

Answer from: miya214

Geologic time uses the layers of rock to describe the relationships of events and their sequence in chronological order over the history of Earth. The layering is a result of the buildup of tiny bits of rock, sediment, or lava cooling at the surface over many years. Think of it like a stack of pancakes—the bottom layer is the one that was placed first and therefore is the oldest. The sediments that create the layers of Earth are stacked one on top of the other.

Answer from: Quest

answer: carbon 14 can only be used to determine the age of the organisms that were once living, and igneous rocks are non living.

explanation:

carbon 14 dating is used to determine the age of the sample by estimating the amount of carbon 14 present in the sample and then comparing it with a reference standard.carbon 14 is a isotope of carbon which is radioactive and unstable. carbon 14 is assimilated by all plants and animals throughout their life from carbon dioxide. however, one the organisms die they stop this assimilation and the carbon 14 content starts to decrease.by knowing how much of carbon 14 is left in an organism after his death, one can estimate the age of the organism. the materials whose age can be estimated by carbon 14 method are the organic compounds. however, some inorganic compounds such as aragonite shell can also be dated.however, if we consider the igneous rocks it is a non living component which never accumulated carbon 14 in it and thus, we cannot use carbon 14 dating method to estimate its age.
