Chemistry of Explosive Volcanoes! Source: (very very very very very important video you have to watch and Analyse the whole video very carefully.)
Discussion Question: – For this unit discussion, Unit 3 discussion, we are going to dive into the chemistry behind volcanos, for the discussion this week, please watch the video below: Chemistry of Explosive Volcanoes! Source:
Discussion Question: – After watching the video, please answer the following and share it with your group:

How do contaminants enter the mantle?
What impact do contaminants have on the lithosphere?
What are the primary contaminants that enter the mantle?
How does silica oxide impact the magma properties as well as eruptive properties?
What are the determinants of the type of magma that will form?
In this course, our discussions are what we describe as ‘asynchronous’; that is, students discuss an assigned question, exchanging ideas related to this question at varying points each week. A key benefit of asynchronous online discussions is that students can participate whenever it is most convenient (although see grading rubric about timing of posts below) and can think about the weekly discussion questions before participating.

In this way, students often feel better prepared as they have read and engaged with the course materials before participating (which is also one of the important aspects discussed in the grading rubric below).
The purpose of the discussion forums is to have students engage with course material and then demonstrate their understanding of course materials by expressing/explaining an idea, responding to other group members’ ideas, and/or developing a thread of ideas together as a group. In this way, students learn from the instructor, the course materials, and each other. It further provides students with ongoing opportunities to review, reflect upon, and apply new knowledge such as concepts, theories, or research findings. This will help when students are working on their two major writing assignments for this course which also requires knowledge of and engagement with course materials.

There will be diverse perspectives and that is o.k. However, all students must strive to be constructive and considerate if they disagree with any of their group members. It is okay to challenge and disagree with each other but only if it is done in a respectful manner.
Note: There is no single ‘right answer’ and the approach you describe need not reflect all of the tactics! The goal here is to generate discussion and share ideas about how best to engage in challenging conversations about climate change.
After you have made your original post, read some of the posts from your classmates and construct one reply post of 100-150 words that responds to one of your group-mate’s original posts. Your reply post should be written such that it does one or more of: identifies something that you find especially interesting or insightful about your classmate’s original post; poses an engaging and relevant question and/or builds on the ideas from your classmate’s original post; raises a real-life experience or observation that you feel would be relevant to illustrate or help further develop an idea or point in your classmate’s original post.
Please note that you will need to make an original post before you can read and respond to your peers’ posts
¨write in 200 words. follow proper guidelines as given in beginning. Use AP7 STYLE OWL PURDE. Provide reference.
Write in on own words.
¨Some points to keep in mind:
Be clear and to the point in your postings.
Edit your work. Your posts should be coherent and use proper grammar and spelling.

Keep postings to 200 words exactly Quality is better than quantity.
Contribute your own thoughts about the material you have read.
Support your thoughts by referencing the video and docx provided and other outside literature.
Raise additional questions or points of discussion to stimulate further discussion
If you have questions, show that you have already tried to find a solution.
Respect the viewpoints of your peers. Ask for clarification if you don’t understand a point. Assume good intentions.
Use the proper terminology introduced in the course readings.
When using literature in your postings, make sure to provide references in proper APA Style.
Show respect and sensitivity to peers’ gender, cultural and linguistic background, political, and religious beliefs.
You are strongly encouraged to take the time to review the following documents on writing quality discussion posting and on taking roles in discussions.

PREPARING TO WRITE1. Read assigned material—critically—and take notes as you read: Who wrote this material (a respected expert? an activist with a specific aim or belief?) Do they have any possible biases? Are studies reliable and valid? (What kind of research was performed?) When was this material written? Are the definitions/conditions/opinions described still accur vant? ate/rele Is an opinion expressed? How might someone disagree? How does this material relate to other concepts and theories you are studying? (Remember, instructors choose readings with a plan in mind—try to imagine why they have assigned this reading) Does the article complement other things you have learned? Is it in opposition? 2. Read and understand the discussion question or topic provided by your instructor • What are you asked to do? (Formulate an opinion? Respond to a question? Explain a concept or theory?) • How are you asked to do this? What kind of information are you expected to include (e.g., supporting quotations or references, examples, etc.) Do you need to bring in outside research? 3. Sort out the finer details • Is there a word maximum? Minimum?

(Most posts will be 1‐2 paragraphs maximum). • How many times are you expected to post? (Find out if you are required to post a certain number of times per question, per week, etc.) • How much of your grade is this component worth? Each post? Budget your time accordinglyAre you expected to respond to other students’ posts? What proportion of original posts versus responses are you asked to provide?INITIAL POSTS – An initial post is a response to the original question presented by the course instructor, or the opening post on a particular topic (i.e., not responding to other students’ posts). Consider each post a “mini‐thesis,” in which you state a position and provide support for it. If you are responding to a question, be sure to 1. Take a position: Provide a clear answer to the question (incorporate some of the wording of the question in your answer if possible). 2. Offer a reasoned argument: Provide an explanation for your point of view, and use evidence from your text, notes, or outside research (where appropriate) to support your point. 3. Stay focused: End with a summary comment to explain the connection between your evidence and the question (how your evidence proves your point). Your post might also introduce a question or idea that others can follow up on. But make sure you have answered the question first!
