I also deviate from the textbook chapter numbering briefly. We did skip Ch8. I blend Chapters 9 and 10 together, so this page here contains some information from Chapter 10 also. Here is an introduction to Plate Tectonics. https://www.youtube.com/watch?v=kq7AnF1iYA8 After watching the video, take the short tectonics questions. Tectonics intro question (5 points - 4 questions) Tectonic Plate Labeling (4 points - 1 question) Instructions Label the tectonic plates by matching the number from the map with its name. You may use your text or an online source to make sure your labels are correct. 2 # Chapter 9 Orogenesis Here is a follow-up video that looks in more detail at Orogenesis (the processes that make mountain ranges). https://www.youtube.com/watch?v=DOqM4U5SM1s Orogenesis questions ( 5points - 5 question) 3 # Chapter 9 Plate Motion Here is a follow-up tectonics video that ties together some of the earlier topics. https://www.youtube.com/watch?v=z3o9K1hf32g Plate motion question ( 2points - 2 questions) 4 # Chapter 9 Geologic Cycle Next, here is a rock cycle video. https://www.youtube.com/watch?v=kGFKHfRHKOY 5 # On-Site Geology Most of the tectonics and geology resources so far are from a textbook. This can be helpful because it means that the rocks shown can be ideal examples of the rocks you are trying to show. It also means that diagrams can be generalized so you can make sense of the extremely complicated Earth. On this page, I've posted a few videos that I made in the field, talking about rocks, showing rocks, talking about the processes that create, transport, and change them. There isn't really anything new that you need, but if you want to check them out, maybe you will appreciate the different settings and explanations. First up, filmed onsite at Gold Creek Ecological Reserve in the San Gabriel Mountains, this video describes how streams function within a landscape to collect and transport material (rocks). It also describes clastic sedimentary rocks. https://www.youtube.com/watch?v=Ce6NlrxVDE8 Next up I discuss a slightly different type of clastic sedimentary rock, a conglomerate (Links to an external site.) . The conglomerate rock I show is part of the Franciscan Formation (Links to an external site.). https://www.youtube.com/watch?v=N9mRPaJgwx0 Changing locations briefly, the next video shows a narrow gorge that is completely formed by very similar conglomerates. It is the Middle Fork of Piru Creek, a remote stream that is in Ventura County. https://www.youtube.com/watch?v=ihyZSuiUEVQ Back to Gold Creek, we see some igneous and metamorphic rocks. https://www.youtube.com/watch?v=s-yDqmUEkMw Re-visiting a conglomerate stone, I focus on an extrusive (volcanic) clast. https://www.youtube.com/watch?v=0bvcVxYLFs8 Finally, we take a look at the landscape features formed as streams transport all of their material towards the ocean. https://www.youtube.com/watch?v=aru6o-Ws2-U Geologic Cycle question ( 3 points - 2 questions) 6 # Earthquake homework ( 5 points - 3 questions) Instructions This course will not go into great detail about the mechanics of earthquakes. A Geology class like Geology 1 would do that. But we will look at the spatial patterns of earthquakes as well as reflect on how to prepare for their inevitability. This assignment will use some web links to help you investigate the locations (spatial patterns) of major earthquakes. CHAPTER 11 1 # Chapter 11 Weathering No, we didn't skip a chapter, but the information from Chapters 9 and 10 are all included on the "Tectonics" page. Here is a short video on weathering, followed by a quick quiz and then a short video quiz assignment. https://www.youtube.com/watch?v=IdR7OStk95M Take the quick quiz covering information on the video. Ch 11 Weathering Quiz (3 points - 3 questions) Instructions Take this short quiz after watching the video on weathering. 2 # Ch 11 Slides and Flows ( 3 points - 3 questions) Instructions Watch several youtube videos of mass wasting events and answer questions about whether or not they show "flows", "slides", or both. 3 # Tectonics and Geology Questions ( 19 points - 12 questions ) Instructions Point values do not necessarily indicate the number of correct responses. Look at each answer carefully on those questions that allow multiple answers. Geography 001: Tectonic ( Ch 9-11) Assignment CHAPTER 9 1. Ch 9 Tectonic Plate Research Discussion 1. Earthquake Preparedness Assignment CHAPTER 9 1 # Ch 9 Tectonic Plate Research Instructions ( 6 points - 5 questions) Choose a tectonic plate OTHER than the Pacific, North American, or Juan de Fuca plate. Research the following questions so that you can enter short answers in the "quiz" that follows 1. 2. 3. 4. 5. What is the name of your tectonic plate? What type of crust is the plate primarily composed of? What type(s) of plate boundaries does it have? Describe any mountain ranges that exist because of its motion. Describe any current geological hazards that are related to the plate. Discussion 1 # Earthquake Preparedness (This is a 10 point assignment, and each question is worth 2 points.) Earthquakes are hard to predict with much accuracy. We have no idea if there will be an earthquake this week, this month, or this year. We do know, however, that earthquakes are inevitable in Southern California on longer timescales. Unfortunately, when things don't happen on a regular schedule, we as humans discount their importance and can "pretend" they aren't real threats, even if all the experts tell us they are inevitable. Sadly, there are parallels with our willingness to prepare for Climate Change, pandemics, etc. In California history, starting with the 1906 San Francisco earthquake, immediately after a major earthquake we have a brief period where we update our state regulations and general preparedness, and then a longer period where earthquakes don't cross our minds. For this assignment, go to a US government website focusing on disaster preparedness (Links to an external site.) to learn about ways to prepare for an earthquake. Specifically, click on the "family emergency communications plan" link on that page. Give some thought, discuss with those in your household, and then make a discussion post that answers questions 1-5 of step 1. Number your answers so I can see that you are answering all 5. Please don't divulge any personal information such as your address or family phone numbers, but do make your post specific to your situation.
