Activity dating relative talambuhay ng dating pangulong ferdinand marcos
The discovery of radioactivity and its application to dating rocks is perhaps one of the greatest scientific achievements affecting the Earth Sciences.
With the discovery of radioactive isotopes more then one hundred years ago, scientists quickly realized that the radioactive decay of materials found in rocks could be used to date the rocks and consequently change the "relative" geologic time scale into an "absolute" time scale.
In this lab, you will apply many of these laws and principles to determine the relative sequence of geologic events that created a particular set of rock layers and intrusions.
Relative dating is used to arrange geological events, and the rocks they leave behind, in a sequence.The method of reading the order is called stratigraphy (layers of rock are called strata).Relative dating does not provide actual numerical dates for the rocks.In this activity, you will be able to combine your knowledge of relative dating methods (learned in Activity 7) with the absolute dating method to determine more accurately the geologic history of a region.Activity 8 is taken from Investigating Earth: A Geology Laboratory Text (1997) by Wiswall and Fletcher.
