The weathering processes lecture goes into a little bit of detail on how primary minerals (feldspars, pyroxenes, quartz and others) decay and transition into clay minerals. The weathering landform lecture explains that clays are a common product of mineral weathering found all over Earth' surface. The soils lecture also covers a bit about how clay minerals are important to soil formation. However, those lectures do not do justice to such an important part of Earth's geography. Thus, this lab practical involves some extra reading about the magic of clay minerals. This is a great slide show on clays to skim (https://web.viu.ca/earle/geol312/USC-anderson- clays.pdf) -( archived file (https://canvas.asu.edu/courses/172892/files/77690578/download?wrap=1) )- just to get you thinking about their structure. This is an interesting speculative article (https://www.space.com/6456-life-crystal-code.html) ( archived file (https://canvas.asu.edu/courses/172892/files/77690533/download?wrap=1) ) about clays and life on Earth. This is a detailed article about eating clays (geophagy) during pregnancy (https://canvas.asu.edu/courses/172892/files/77690479/download?wrap=1) .

Clay minerals store key nutrients for the first life to evolve. Clay minerals store water to help the first life to evolve. Correct! Some researchers belief that the crystalline structure of clay minerals offered a chance for RNA and cells to first develop. Clays apparently can help RNA form. Also, clays can help cells form. Certainly, however, the research is speculative.  Question 2 0.5 / 0.5 pts Clay minerals can reduce anxiety. Clay minerals can give hallucinations. Clay minerals provide a natural alternative to coffee. Correct! In places where other sources of nutrients are lacking, clay minerals are able to absorb a variety of nutrients such as magnesium, calcium, and iron. Thus, the craving during pregnancy for eating clay minerals could be to supply these nutrients. The best answer is that the nutrients that adsorb to clays are what some pregnant women crave. Thus, by eating certain types of clay minerals, key nutrients are provided. There is some research that the nutrient iron (http://www.ncbi.nlm.nih.gov/pubmed/23787405) is provided by geophagy.  Question 3 0.5 / 0.5 pts Please read this article about the influence of clay minerals on life (https://www.sciencedaily.com/releases/2013/11/131105132027.htm) . If that article is not available, you can try this link (https://www.space.com/6456-life-crystal-code.html) . What role might clay minerals have played in the evolution of life on Earth? Please read about geophagy or about eating dirt. This is a detailed article about eating dirt (including during pregnancy) (https://canvas.asu.edu/courses/172892/files/77690569?wrap=1) (https://canvas.asu.edu/assessment_questions/12982712/files/25702725/download? verifier=qbkom8svS7681hAe2EtSKS1mxcouFVHvDVb7lYUm&wrap=1) , but you can just skim it to learn the answer to this question. Question: why would pregnant women want to eat clay minerals?
