LAB 11 - Geologic Time Question 1 What type of unconformity is shown by the red line in this image? Answers: Angular Unconformity Nonconformity Disconformity Question 2 What kind of unconformity is indicated by the red line in this image? Answers: Angular Unconformity Disconformity Nonconformity Question 3 What kind of unconformity is indicated by the white line in this image? (Layers above and below line are parallel.) Answers: Disconformity Angular Unconformity Nonconformity Question 4 How is C-14 created in our atmosphere? Answers: The photosynthetic process of plants produces C-14 as a by product. C-14 is a industrial pollutant created by the combustion of fossil fuels. Cosmic rays bombard our upper atmosphere and cause N-14 to transmutate (change) into C-14. It is produced by the decay of C-15. Question 5 What is the half-life of C-14 and what is its daughter element? Answers: About 1 hour, B-14 About 1.5 billion years, Pb-206 About 1 million years, C-13 About 5,700 years, N-14
