Chapter 7 – Plate Tectonics

4. Textbook Review Question (4pts)

5. Textbook Review Question (4pts)

Looking at the world plate boundary map on pages 202-203 in your textbook (13th Ed), name 4 plate boundary pairs and what type of boundary they share. (For example: Australian-Indian Plate & Antarctic plate = Divergent Boundary)

6. Real World Examples – Essay Question

(**4pts for summary, 2pts – for correct APA format in-text citations and reference list)

Do a quick Internet or magazine search for news concerning plate tectonic motions causing changes to Earth Spheres. Summarize the article in your own words and explain how it pertains to the topics of plate tectonics and changes in the Earth’s four spheres (or one of the spheres). Your summary should be no more than 2 paragraphs and must be in your own words, and at the level of this course (meaning don’t just copy the article wording).

This assignment will give you practice in summarizing scientific work in your own words and practice citing sources correctly. Use APA 6th Ed. in-text citations and bibliography style in this short summary. You may only have 1-2 citations (the article and your textbook) and that is fine for this short essay.
