All the other possible answers here are correct.Correct!Correct!1 / 1 ptsQuestion 6The age of the Earth can be estimated in many ways. Which statementbelow is most accurate (remember that uniformitarian calculations involvelooking at the thickness and type of sedimentary rocks, and similar things,but do NOT include radiometric dating or counting of annual layers)?Correct!
4/1/19, 5:47 PMRockOn #10: GEOSC 10 Spring 2019, MergedPage 7 of 17Uniformitarian calculations show that the Earth is more than about 100 millionyears old, and radiometric techniques tell us how much older.
