16 20 On the sediment cores in Figure 5.4 on page 8, correlate the sediment type by drawing a line where the lithology changes in one core to the same lithology change in the adjacent core. Do so for all three cores, and all lithologic changes. The first one has been done for you in blue on Figure 5.4 as an « xampl Does your correlation based on lithology agree with the correlation based on foraminifera nges? (circle one No In general, what is happening to the lithologic correlation lines in relation to the fossil cor- relation lines? In other words. are the lines crossing, parallel, or are they doing something different? The lithologic lines in relation to fossil lines vary. While there are some parallel lines there are also crossing lines. | would argue that a majority of the lithologic lines correlate to fossil lines because there are more parallel lines than crossing lines. Furthermore, a majority of these crossing lines are closer to being parallel than perpendicular. Based on your answer to question 18, do you think similar changes in lithology always occur at the same time across sites/cores? Why or why not? (answer in 2 to 3 sentences Based on the knowledge I've acquired from this lab and from class, | would assume similar changes in lithology happen at relatively the same time based on how close the sites are. Due to lithology and cores being from the ground , | would infer that similar lithologic changes take place for those areas that are on the same tectonic plate or even places that have similar climates. | think there is also something to be said for patterns in nature and | think you can find trends throughout much of the data in this lab. What do vou think is a limitation of using lithology to correlate betwees Which correlation method is best in this examp using the dates from fossils
