Geology Exam # 3 Questions And Correct Answers What does uniformitarianism mean? We can interpret the processes that formed ancient rock by examining the processes that form similar rock today. In this illustration, which is a correct interpretation of relative ages? The granite pluton is older than the fault, which is older than the dike. Which of the following is the MOST PRECISE estimate of when the folding occurred? Before the granite pluton intruded, and after intrusion of the...

radiometric dating - general approach used to determine the age of specimens using the rate of decay of radioactive isotopes radiocarbon dating - a chemical analysis used to determine the age of organic materials based on their content of the radioisotope carbon-14 potassium-40 dating - radiometric dating method often used in the assessment of volcanic intrusions in sedimentary layers. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K) into ar...

What is the process component of the theory of special creation? - Species were created, instantaneously and independently of each other, by God What is the pattern component of the theory of special creation? - Species are recent, unrelated to each other, and do not change through time What is the pattern component of Lamarckian evolution? - Species change in a progressive manner, meaning that they get larger and more complex over time The geologic record and radiometric dating are incons...
