14.Geological evidence based on several radiometric techniques has provided a scientifically well-accepted age for the Earth. Represent that age of the Earth as the 100-yard length ofa football field, and any time interval can be represented as some distance on the field. (So something that lasted one-tenth of the age of the Earth would be ten yards, and something that lasted one-half of the age of the Earth would be fifty yards.) On this scale, how long is written history?A) 50 yards.B) Just over 10 yards.C) 1 yard.D) 1 inch.E) Just over the thickness of a sheet of paper.Feedback: If the 4.6 billion years of Earth history are 100 yards, then the few thousand years of written history are just one-millionth of that history, just over the thickness of a sheet of paper.Table for Individual Question FeedbackPoints Earned:0.0/1.0Correct Answer(s):E15.What is accurate about the scientific results learned by counting annual layers in ice cores?the glaciers. with no older ice.
