o OO Figure 6-E4 | Block diagram to use to answer questions 7 and 8. Unconformities are shown in red. Source: Bradley Deline (2015) CC BY-SA 3.0 view source 7. (8 pts) Examine Figure 6-E4. All the layers in this block diagram are composed of sedimentary rock and the unconformities are colored in red. Using Figure 6-E4 and the geologic laws and principles discussed earlier and following the examples shown in the overview section (online), place the geologic events listed below in the correct relative time sequence in the table below, in order from oldest (1) to youngest (8) a. Tilting b. Uplift and erosion (angular unconformity) c. Deposition of sedimentary beds 10-13 d. Uplift and erosion to current position e. Deposition of sedimentary beds 7-9 f. Uplift and erosion (disconformity) g. Deposition of sedimentary beds 1-6 h. Fault. Event order: 4 Oldest Youngest 8. (6 pts) Label the sedimentary beds in Figure 6-E4 in order of age from oldest (1) to youngest (13) 82
