Pre-lab questions II. Experiment 1 III. Experiment 2 Includes:  Legible photos or scans (with name card and signed) of completed three colored-pencils sketches as directed  YouTube video requirement  Legible photos or scans (with name card and signed) of worksheets 1 and 2 Stratigraphic Correlations

Please note: for any questions that require additional research, consider using Google Scholar instead of Google. Also, any information taken/used from a source should be properly cited. PRE-LAB QUESTIONS 1. What types of sediments are you most likely to find close to an ocean beach? Far from a beach in the deep ocean? When you’re near an ocean beach, you’re more likely to find sand and pebbles, and the sediment will get finer as you move deeper into the ocean. 2. Describe how you can identify periods of transgression and regression given a stratigraphic column. When observing a stratigraphic column, you can identify periods of transgression or regression but the presence of some form of the limestone-shale-sandstone or sandstone-shale-limestone pattern, which occurs as the energy changes during transgression and regression of seas and oceans. 3. Give two reasons (and an example for each) that the thickness of beds varies in correlated stratigraphic columns. One reason the thickness in beds varies in correlated stratigraphic columns would be the conditions of the deposition, for example, if one column was pulled from an area that was a beach and one several meters away, you’d see less sandstone remains and more silt or carbonate remains left behind. Another reason thickness in beds could vary could be that the areas of the columns both experienced different types of weathering and erosion during formation that could change the thickness of the layers. 4. What is the difference between a facies and a stratigraphic column? Facies are physical properties of the rocks that give us information on the depositional environment. Stratigraphic columns contain different facies within them and are maps of the depositional environment over time. Stratigraphic Correlations
