how do scientists use relative dating to study the geologic history of other planets

All the data from Earth and beyond has led to the estimated age of 4. Original horizontality helps us establish that folding or tilting events happened after the sedimentary strata formed, hence important in relative dating. Graph of number of half-lives vs. The geologic time scale was completely worked out in the 19th Century using these principles without knowing any actual numeric ages for the events. The original material has almost always been replaced with new minerals that preserve much of the shape of the original shell, bone, or cell. Of course, except for the crossbedding.
