Answer 1

QUESTION 6 This table lists the chronology of events, with three already filled in, beginning with the oldest event. Your task is to use your understanding of relative dating principles (superposition, cross-cutting. etc.) and unconformities (nonconformity, etc.) to complete the table by selecting the missing events and placing them in correct sequential order. Squiggly lines in the illustration implies modern day erosion or unconformities, i.e. missing geologic time. Event 1 Magma cools slowly beneath the earth's surface to form granite Event 2 INTRUSION OF QUARTZ VEIN Event 3 UNCONFORMITY Event 4 DEPOSITION OF CONGLOMERATE Event 5 Deposition of sandstone Event 6 Deposition of shale Event 7 TILTING Event 8 SURFACE OF EARTH Match each event description to its correct numeric sequence to fill in the missing events. For example, find the description you believe represents Event 2 and select its corresponding letter from Repeat this for each missing event. The right (Event 3-7) Tilting of rock layers EVENT 7 A Event 3 B. Event 8 Subsidence and deposition of conglomerate forming an uncomformity EVENT 4 Modern day uplift and erosion EVENT 8 C. Event 4 D. Event 2 Remember here the quartz vein is younger than the unconformity otherwise it would have crossed the unconformity surface and deposit over the unconformity. E. Event 7 First period of uplift and erosion EVENT 3 Quartz vein intrudesEVENT 2 QUESTION 7 In cross-section 1, what type of unconformity exists between the granite and congiomerate? OA disconformity O B. angular unconformity C. nonconformity O D.conformity
