BIO112 Spring 2024 Exam 1 Terms 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 isot...

radiometric dating the process of assigning "ages" to rocks and fossils based on the breakdown of certain elements into other elements eugenics a "science" founded by some of Darwin's followers, of selectively breeding humans to produce a "master race" index fossil a fossil used by evolutionists to identify the "age" of the rock layer containing it William Paley the 18th-century British theologian who argued that living things show clear evidence of design Charles Darwin the Br

Geology GE 2000 Exam 2 Questions and 100% Correct Answers ka, ma, ga - CORRECT ANSWER-thousands, millions, billions Catastrophism - CORRECT ANSWER-sudden & obvious to humans Gradualism - CORRECT ANSWER-NOT obvious to humans (ex: Glaciers, plate tectonics) Uniformitarianism - CORRECT ANSWER-"The present is the key to the past" Earth is shaped entirely by the same forces still in operation today, acting over a very long period of time. Relative Age/Time - CORR...

List the current scientific consensus of the age of the a) Universe, b) Earth, and c) Moon, and explain how scientists have calculated these ages - a) Age of the Universe: 13.77 +/- 0.04 billion years old (Measured by calculating how fast our universe is and has been expanding since the Big Bang) b) Age of the Earth: 4.54 +/- 0.05 billion years old (Measured by radiometric dating of meteorites that formed at the same time as Earth.) c) Age of the Moon: 4.425 +/- 0.025 billion years old (M...

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...
