https://padlet.com/wismerd/ts1zvc92njtm What limitations or difficulties did you encounter en-us 2018-02-21 18:41:52 UTC 2026-03-04 01:24:03 UTC hello@padlet.com https://padlet.com/wismerd/ts1zvc92njtm/wish/234186304 I found it difficult to determine what was a "dark" layer and what was a "light" layer aside from the extremes. As well as this, when the layers converged, I didn't know when to call it two layers or one layer. Aside from this, I think this method of dating could be quite reliable, as we have a set amount of layers to call it a year, two. So if we always see a set of two, counting off by them can give roughly an exact amount of years a fossil is.]]> 2018-02-22 13:09:26 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234186304 https://padlet.com/wismerd/ts1zvc92njtm/wish/234186540 I thought it was difficult when counting the layers. It was hard to tell which was a darker layer, and which was a light layer. If you can not tell, it alters your results and makes them inaccurate. I do not think this is an accurate way of absolute dating fossils. Because there is no exact number, many people will come to different conclusions. I think there is a better way of absolute dating fossils that will be more accurate. When there were layers all pressed together, you could not tell how many layers were together. This is another reason your counting would be inaccurate.

If they were all in a clump together, it was hard to separate them to different layers. I don’t think it is a great reliable source, but I do think it is an easy way to determine the ages of them, seeing how many seasons they went through.]]> 2018-02-22 13:10:43 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234186832 https://padlet.com/wismerd/ts1zvc92njtm/wish/234187057 I thought it was difficult when we had to count how many layers there were. It was hard to see if there was a dark layer or a lighter layer. Also, for the thick black layers, I couldn't tell how many lines were there. ]]> 2018-02-22 13:11:17 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234187057 https://padlet.com/wismerd/ts1zvc92njtm/wish/234187479 It was pretty hard to count the dark layers because they weren’t that clear and when there was a section of dark layers it was hard to tell how many were there. I don’t think this is a very reliable way of absolute dating because the results can vary and there is no right answer.]]> 2018-02-22 13:12:20 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234187479 https://padlet.com/wismerd/ts1zvc92njtm/wish/234187513 I though that it was difficult to count the darker layers because they often were very close together and it wa shard to tell if they were one layer or multiple. This could mess up how many total varves there are when you are counting.]]> 2018-02-22 13:12:25 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234187513 https://padlet.com/wismerd/ts1zvc92njtm/wish/234187680 I thought it was difficult because the lines were sometimes close or the color wasn’t bold enough to tell if it was a line. I feel like it is an unreliable source of absolute dating because there seems to be different results that may come up for each person. There is no exact answer for it.]]> 2018-02-22 13:12:50 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234187680 https://padlet.com/wismerd/ts1zvc92njtm/wish/234187737 It was hard to tell the difference between some layers because some layers were thinner than others. Varve counting can be accurate if it is done correctly, but if not, it is inaccurate.]]> 2018-02-22 13:12:57 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234187737 https://padlet.com/wismerd/ts1zvc92njtm/wish/234187950 It was hard to count the different layers sometimes because you were not able to tell if it was a layer or not. I don’t think this is reliable for people to use because people aren’t going to get the same number time and time again it is going to change when other people try to count the varves ]]> 2018-02-22 13:13:25 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234187950 https://padlet.com/wismerd/ts1zvc92njtm/wish/234189027 I found it was difficult to count the varves. It got hard when it came to the dark thick areas because you don't know how many layers are in that area. This method isn't reliable because everyone will get different answers.]]> 2018-02-22 13:16:04 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234189027 https://padlet.com/wismerd/ts1zvc92njtm/wish/234189112 I don’t think that this method of absolute dating is very accurate. People often get confused on what to consider dark or light. It also is very difficult to count because there were so many layers and they were very small. I think it would be a more perfected system if we had some kind of machine to read it because it would eliminate human error.]]> 2018-02-22 13:16:18 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234189112 https://padlet.com/wismerd/ts1zvc92njtm/wish/234189918 It was not only difficult to count, but I was a bit confused. I am mostly not sure if the large black layers were separated by smaller lighter layers or just a huge layer. On the black and whote paper, it felt near impossible to find fine layers since they blended into others. The small interconnected layers also confused me since It was hard to tell if they were parallel to the layer or were separate to it.]]> 2018-02-22 13:18:08 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234189918 https://padlet.com/wismerd/ts1zvc92njtm/wish/234191528 I thought it was difficult when we had to count the layers. It was easy to accidentally skip some layers when counting and not see them. Some layers were barely even visible when I was counting them. Also, some of the lines were too curvy and seemed to mess with some of the other lines. I do not think this is an accurate way of dating the fossils. It is easy to mix up the counting which would make the results different from what it should be, meaning it would be inaccurate.]]> 2018-02-22 13:21:52 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234191528 https://padlet.com/wismerd/ts1zvc92njtm/wish/234191726 I found the varve counting difficult. The layers were hard to count because some of them are so thin and in other cases, it’s hard to tell if the layer is dark or light. Another problem I had was with the black and white paper, I couldn’t always tell with the larger black layers if they were separated by other layers or just one big layer.]]> 2018-02-22 13:22:21 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234191726 https://padlet.com/wismerd/ts1zvc92njtm/wish/234191907 I think that varve counting is a bit difficult because the varves are so thin. I don’t think this method is that accurate for us. When my group would recount the varves we would get a different number of them than before. I think if this is done by more experienced people there would be more accuracy. ]]> 2018-02-22 13:22:45 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234191907 https://padlet.com/wismerd/ts1zvc92njtm/wish/234192441 In my opinion, I didn’t really like this form of dating rocks as much when compared to other methods we have tried. The activity was hard to do because it was difficult counting every single layer accurately, especially since some were so thin that seemed faint. Almost like the layer were rubbed way too many times, and at some point just started to blend with each other. This is me speaking from only having the experience with the black and white papers.]]> 2018-02-22 13:23:53 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234192441 https://padlet.com/wismerd/ts1zvc92njtm/wish/234193241 The varve counting was a bit difficult because it was hard to tell which ones were separate layers. I don’t believe it’s very accurate because everyone can count different varves as layers and get a different number each time. If we all get different answers it will be difficult to find how old a fossil is.]]> 2018-02-22 13:25:40 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234193241 https://padlet.com/wismerd/ts1zvc92njtm/wish/234194209 I found that counting varves is rather hard And not very accurate since it was hard to tell what layers were separate, because there were many layers bunched together so you can not tell exactly how many varves are even there. This makes this method of dating unaccurate way of absolute dating.]]> 2018-02-22 13:27:52 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234194209 https://padlet.com/wismerd/ts1zvc92njtm/wish/234194464 I found that counting the individual varves was a very difficult and unreliable way to find the age of a rock. Sometimes the layers were very small and difficult to detect.]]> 2018-02-22 13:28:22 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234194464 https://padlet.com/wismerd/ts1zvc92njtm/wish/234548602 I found it difficult to count the layers. That is because they were so close to eachother, you could’ve missed one. It was hard to count the dark ones because they were close to each other. Everyone got different amounts and this method is inaccurate.]]> 2018-02-23 01:36:14 UTC https://padlet.com/wismerd/ts1zvc92njtm/wish/234548602
