The primary basis for classifying detrital (clastic) rocks is _______, whereas the primary basis for classifying chemical rocks is ________.  A. sorting ; density  B. crystalline structure ; sorting  C. rock type ; rounding  D. particle size ; mineral composition  E. particle shape ; trace elements Question 4 of 50 2.0/ 2.0 Points Pyroclastic flows are more associated with __________.  A. cinder cones  B. shield volcanoes  C. stratovolcanoes  D. flood basalts  E. ocean hot spots Question 5 of 50 2.0/ 2.0 Points Which type of faulting is most dangerous in Utah?  A. Reverse  B. Strike-slip  C. Thrust  D. Transform  E. Normal Question 6 of 50 2.0/ 2.0 Points What information is needed to determine the distance from the epicenter of an earthquake to a seismic receiving station?  A. The transverse nature of the s-wave  B. The amplitude of the seismic waves on a seismogram  C. The time interval between the P and S waves  D. The magnitude of the earthquake  E. The difference between the amplitude of the seismic waves Question 7 of 50 2.0/ 2.0 Points Applying the principles of relative age-dating to the diagram, which of the following is TRUE. Explanation of the diagram: "A" represents an unconformity (erosional surface), "B" is a basaltic dike, "C" is a shale formation, "D" is a sandstone formation, "E" is a limestone formation, "F" represents a thrust fault.  A. D is YOUNGER than C  B. E is OLDER than B  C. F is YOUNGER than A  D. A is YOUNGER than C  E. B is OLDER than F Question 8 of 50 2.0/ 2.0 Points The map below shows continental land as green and brown, the depth of the ocean floor in blue, and tectonic plate boundaries as colored lines. Evaluate this geologic evidence to determine which location would most likely require adequate tsunami preparedness
