Relative dating utilizes six fundamental principles to determine the relative age of a formation or event the first principle is the principle of superposition which states that in an undisturbed succession of sedimentary rock the oldest layers are on the bottom.
Fossils and relative dating fossils are important for working out the relative ages of sedimentary rocks throughout the history of life different organisms have appeared flourished and become extinct many of these organisms have left their remains as fossils in sedimentary rocks.
Geologists establish the age of rocks in two ways numerical dating and relative dating numerical dating determines the actual ages of rocks through the study of radioactive decay.
Part 1 determining relative age of rocks each team of 3 to 5 students should discuss together how to determine the relative age of each of the rock units in the block diagram figure 1 after students have decided how to establish the relative age of each rock unit they should list them under the block from most recent at the top of the list to oldest at the bottom.
