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...

I.e. How old is the Earth? - -Focuses on the natural world I.e. Can we analyze the atoms with radiocarbon dating to determine the age of the rocks? - -Uses testable ideas I.e. Other scientists challenge the current age of the earth when they discover new evidence or processes for determining age - -Involves the scientific community I.e. Objects found in nature such as fossilized organisms, plants, and bones can be tested for their age - -Relies on evidence I.e. Three characteristics of sc...

ANP 203 Exam 2 Questions with complete solution how do archaeologists order artifacts into time series (seriation) using the principle of superstition? how do artifacts serve as time markers and help archaeologists cross-date sites? artifacts are ordered earliest (deeper) --> latest, (overlie) showing that deeper, underlying levels are older than those that overlie them. some artifacts that are dated can serve as markers for similar artifacts that are not yet dated and help sequence these....
