Ether the principle of superposition(also called the law of superposition- concept that the layer of sediment that is deepest is the oldest) or stratigraphy which is the study of layers, when using knowledge of when certain species existed and remains of those species while also studying the layers it is called biostratigraphy.

What two ways do scientist use fossils to determine the environmental changes?
its radioactive dating and relative dating
What are two ways geologists determine the age of fossils?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
What two methods are used to determine the age of a rock?
The two methods are relative dating and radioactive dating for fossils. I think it's the same for rocks.
How are stratigraphic and radioactive dating different in regards to how they date fossils?
Radioactive dating refers to the process of measuring the age of an object using the amount of a given radioactive material it contains. Relative dating, meanwhile, measures the order of past events, without determining their absolute age.
What two types of dating techniques are used in dating fossils?
Body fossils and trace fossils are the principal types of evidence about ancient life, and geochemical evidence has helped to decipher the evolution of life before there were organisms large enough to leave fossils. Estimating the dates of these remains is essential but difficult: sometimes adjacent rock layers allow radiometric dating, which provides absolute dates that are accurate to within 0.5%, but more often paleontologists have to rely on relative dating by solving the "jigsaw puzzles" of biostratigraphy.Classifying ancient organisms is also difficult, as many do not fit well into the Linnean taxonomy that is commonly used for classifying living organisms, and paleontologists more often use cladistics to draw up evolutionary "family trees". The final quarter of the 20th century saw the development of molecular phylogenetics, which investigates how closely organisms are related by measuring how similar the DNA is in their genomes. Molecular phylogenetics has also been used to estimate the dates when species diverged, but there is controversy about the reliability of the molecular clock on which such estimates depend.
Principle that allows rock layers in different places to be correlated based on their fossils?
Relative dating by index fossils.
True or False Fossils may be dated by either the relative dating method which determines the relative order of fossils or by the absolute dating method which uses radioactive isotopes?
True
What are two of determining a fossils age?
The two methods are "RELATIVE DATING" and "ABSOLUTE DATING". :)
Which type of dating uses index fossils?
Relative dating. Paleostratigraphy correlates layers of rock using index fossils found within them.
How does relative dating and absolute dating help scientists assemble a fossil record for an area?
Relative dating is the science determining the relative order of past events, without necessarily determining their absolute age Absolute dating is the process of determining an approximate computed age in archaeology and geology.
What two ways do scientist use fossils to determine the environmental changes?
its radioactive dating and relative dating
How does relative dating enable palenteologists to estimate a fossils age?
by comparing its placement with that of fossils in other layers of rock
Why do scientist find relative dating easy?
because it is easier to find the age of fossils
Is dating real?
i think that realitive dating is dating in real life and not online... please tell me if im wrong well that is 100% wrong.....relative dating is to do with the dating of fossils.....
What is realative dating?
i think that realitive dating is dating in real life and not online... please tell me if im wrong well that is 100% wrong.....relative dating is to do with the dating of fossils.....
What are the two ways to date a fossil?
Radioactive isotope dating (potassium, argon) and relative dating, comparing with fossils of the same characteristics with known dates. Particularly if they are known to be 'zone fossils'
What information does relative dating provide to paleontologist?
it provides how old the fossils are. it tells the paleontologists about how long ago those fossils were set in the ground.
