Sedimentary Rocks Identification Lab Before you start this lab, watch the Sedimentary Rocks Part 1and Part 2 videos under Learning Activities. (Notes from this lecture are posted on the Study Guide for Exam 2 Edit From #33-#55 Highlighted in Yellow) The Laboratory about Sedimentary Rocks is from page 147 to page 181 in the Lab Manual. Objectives: Beable to describe, classify, and identify hand samples of sedimentary rocks Complete the Sedimentary Rocks Identification Table Read “A Practical Guide to Sedimentary Rock Identification” on pages 159 to 161. Where might this sediment have been deposited/precipitated? Use the information from lecture, Page 165 in your lab manual and Page 165 Old (below). What depositional environment could the rock be forming in today? The “Sedimentary Rock Field Notes” file is there to help with the Identification of the Sedimentary Rocks. Some of the information in this file is about using Hydrochloric Acid on the rocks. If you place one drop of dilute Hydrochloric Acid (HCl) on a rock that contains Calcite (CaCO3), then it will fizz and bubble (effervesce) because of the chemical reaction that takes place. If you place one drop of dilute Hydrochloric Acid (HCl) on Dolostone (CaMg(CO3)2), then it will fizz and bubble (effervesce) weakly because the chemical reaction is weaker. Watch this short video on youtube: https://www.youtube.com/watch?v=Lw3bWR0Ws7M The rock samples are located in Sedimentary Rock Samples.

“Complete the attached atmospheric layers review. Upload back here when complete. Use your lecture notes and your chapter reading to guide you. You may submit more than once. This is a graded assignment.
This assignment is a word document and can be completed on your computer and then submitted. This assignment does not have to be printed. While this assignment may appear to be a lower level simplistic assignment, The atmospheric layers play a role in climate change, why we fly planes at certain altitudes, and why we hear static on radios. In addition, it is a competency you will see on your certification exam. “

Complete the attached worksheet on Volcanism and Earthquakes. Upload back here when complete. Use your lecture notes and your chapter reading to guide you. You may submit more than once. This is a graded assignment.
This assignment is a word document and can be completed on your computer and then submitted. This assignment does not have to be printed. Recall some of the rocks we discussed and the process of plate tectonics. Much of the past info we just learned will come together in this assignment. Because it brings many concepts together that we learned, ensure you allocate enough time to this assignment. Take each task one step at a time. Do not read through the whole thing at once, you will get overwhelmed. If at anytime you have questions, email me and I will clarify. Don’t spend tons of time in confusion. The assignment is time consuming enough. Reach out!
Example Graph of Eruption Size vs. Eruption Frequency in Google Sheets with Instructions
Steps for making a graph in Google sheets:
1. Open Google sheets
2. Click on the + sign at the upper left under where it says “Start a new spreadsheet”.
3. Enter the Frequency of Eruptions into column A and size of eruptions in column B.
4. Select both columns A and B including titles (highlighted text in step 3.
5. Click on “Insert Chart” which is the 4th icon from the right in the G. sheets menu.
6. Click on “Chart Type” and select “Scatter Chart.”
7. Select “Customize” under where it says “Chart Editor”
8. Click on “Series” and find the “Trendline” box and select it.
9. Below the “Trendline” box, select Logarithmic
10. Below the “Line Opacity” box, click on the “Label” menu, and select “Use Equation”–this will insert an equation at the top of the chart below the title. You can then use this equation to extrapolate to a “1000-year” lava flow by substituting 1000 for x in the equation. When you do this, you will have to use the natural log. function on a calculator.
( I have attached pictures of graphs for examples).
To get this graph in Excel, you need to select your data ranges with eruption frequency in the left column and size of eruption in the right column. Then you have to insert a scatter chart without any markers. Then you can right click on a date point, select trendline and choose “logarithmic” and then scroll down in the same menu where you selected the trendline and click on “Display equation on chart”. In my chart (see below), I selected linear and logarithmic (curved) trendlines for comparison. You can then use your trendline equation and substitute 1000 years for the x-variable to extrapolate for a “1000 year” lava flow.

1) Regional geology including geological column and geological history (1 page each)
2) 3 cross-sections of the map
3) Pre-pegmatite map – no need to draw a new map, just show on the existing map the rocks that were there instead of pegmatite.
4) Gold resource estimation – approximate, no need using special software

Write a 500-word or two-page essay summarizing two volcanic eruptions and two earthquakes which took place over the past two years (Each event can be a paragraph or a half-page). Use ordinary indentations, double-spacing, and a 12-point font such as Times New Roman. You may have to look at multiple reports on the same story to find a report which is more detailed and not just a short blurb.
I would encourage you to use specific and quantifiable facts in your summaries rather than vague generalizations. At the end of your summaries it may be to your benefit to include a list of your sources, e.g., the url addresses you visited. – from the professor

For this assignment, you are going to review different geologic hazards. Select a location in the United States (we recommend that it be within the contiguous 48 states) and to write a 2-page, double spaced report on the geologic risks of that location.
