Sediment Analysis Lab Your responses must be in your own words. Introduction 1. How big is a boulder? Convert 256 mm to inches. (2 points) A boulder that is 256 mm and converted to inches is approximately 10.07 inches 2. How small is clay? Convert 1/256 mm to inches. (2 points) Because clay is many particles clumped together when weathering occurs. When clay is formed, there are trillions and trillions of clastic sediments. 0.000153789 3. Can you see clay particles without a microscope? Explain. (2 points) Clay, sand, and silt are the three smallest pieces of soil that are going to be needed to be seen through a microscope. An electron microscope is needed to see these smaller clay particles. Section 1 Complete the Sediment Analysis Quiz - Part 1 to complete the first portion of the Cumulative Sediment Data Table. Section 2 Complete the Frequency Distribution graph. (6 points) Answer the following questions: 4. Do any of your Phi sizes seem to have an extremely high percent by weight? (2 points) No none of my weight have high percentage. 5. If all the Phi sizes were the same percent by weight, what would this imply? (2 points) If all the sediment was sorted, I think that means that all the grains are around the same size. Each rock and mineral are different, and they all hold a different distribution which can make the Phi scale vary from rock and mineral. 6. How else could you plot or analyze this data? (2 points) I think that you can use similar tools used in baking. I think that you can sort through the sand for periods of time, and you can examine how coarse the grains are, and according to faculty.njcu.edu, the other three ways that I learned about liquefying grain.

Sediment Analysis Lab Section 3 Complete the Sediment Analysis Quiz - Part 2 to complete the remaining portion of the Cumulative Sediment Data Table. (10 points) Section 4 Complete the Cumulative Curve graph. (6 points) Answer the following questions: 7. Do any of the sample jars have steep verticals? What would this imply? (2 points) A couple of my sample jars did have a steep vertical. when graphing, a few of the graphs simply just shot up by one number when was added. 8. Do any of the sample jars appear extremely unsorted? Sorted? (2 points) all of them look unsorted. 9. Which plot is easier to understand: the histogram or arithmetic curve? Explain. (2 points) The plot that was a lot easier to understand, was the arithmetic curve. I feel that this graph is a lot easier to see because you can see an increase as the numbers goes up. However, if you are plotting on a histogram, you can see the differentiation between all of the materials. Page 2 of 2 GLY1010L - Physical Geology Lab- c.2457607
