Read the following articles and then answer the questions below each. Put your answers in a Word document (or something similar) and upload it here.Steps:Read this Wikipedia articleLinks to an external site. on rare earth metals (internet link) and answer the following question:Using the table at the top of the Wikipedia article, list the 17 rare earth elements. Find them on the Periodic Table. Other than Scandium and Ytterium, where are they all located? Check out this graphicLinks to an external site. about smartphones and the metals they contain (internet link) and answer the following questions:In what parts of a smartphone are the rare earth elements concentrated?What non-rare earth metal is present in nearly every part of a smartphone?Read this ScienceNews article on rare earth mining (internet link)Links to an external site. and answer the following questions (a pdf version of the article is included below in case you have trouble accessing it)Rare earth mining.pdfActions (pdf version of the article above)Where was the largest rare earth mine in the world? (Until the 1990s). The mine was shut down in 1997. What was the cause?The Bayan Obo rare earth mine in China is one of the most polluted places on Earth. What are some of the medical symptoms local residents suffer from?What is the most difficult part of the rare earth production process?Read this ScienceNews article on recycling rare earth metals (internet link)Links to an external site. and answer the following questions (a pdf version of the article is included below in case you have trouble accessing it)Rare earth recycling.pdfActions (pdf version of the article above)How much more rare earth metals are we mining today than in the 1950s? What fraction of these metals are being recycled?Other than caustic hydrochloric acid (the traditional method) what are three new methods for recycling rare earth metals being researched today?How this assignment will be graded:This assignment is worth 40 pts. Each of the questions above (marked by bullet points beneath each article) is worth 5 pts. I'm looking for completeness and clarity.Course AI policyJust as a reminder, the course AI policy is summarized below. My goal in creating this assignment is to introduce you to a group of geologic resources that are already shaping your life on a daily basis, that will only become more critical and relevant as time passes, and that you need to be aware of to be an informed citizen of this country and of the world. As such, I want you to actually read and learn from the resources I provide and think about the questions I ask you to answer, rather than having an AI algorithm do it for you.If you use AI to complete the assignment, make sure and cite all the text, images, or other content that was generated by AI. This means putting in in quotations and citing where it came from, just like citing any other outside sourceI don't care about the specific format used to cite AI (MLA, APA, etc.), just make sure you include these four things:Put text in quotes; add a caption to imagesGive the AI tool name (e.g., Gemini, ChatGPT, etc.), version number, and date you used itInclude the full prompt you used to generate each piece of content.You can include the above info at the end of your assignment in a "sources cited" section if you wantIncluding AI-generated text and images in an assignment without doing the above constitutes academic dishonestyIf you need a refresher, watch this video where I explain the AI policy in more detail
