First view Lecture Set 5, read Chapter 5 in your textbook, and complete the Discussion Questions related to the same lectures & chapter. Many of the questions are derived from the Check Your Understanding box at the end of each section, while some come from the lecture concepts. Instructions Click “Take the Quiz” button to begin. Each question has its own set of instructions. Read carefully. Click “Submit” when finished. How you'll be graded You have three attempts to complete this assignment. There is no time limit on those individual attempts. Each question is worth a certain number of points, and you’ll earn points for each correct

Attempt History Attempt Time Score KEPT Attempt 2 9 minutes 14 out of 14 LATEST Attempt 2 9 minutes 14 out of 14 Attempt 1 9 minutes 11.5 out of 14 Correct answers are no longer available. Score for this attempt: 14 out of 14 Submitted Jan 28 at 7:37pm This attempt took 9 minutes. Question 1 0.5 / 0.5 pts Because the vast majority of spreading centers produce volcanism high in the mountains where no one lives. Because the vast majority of spreading centers produce volcanism on small islands where no one lives. Because volcanism at spreading centers is insignificant by volume compared to other types of plate boundaries. Because the vast majority of spreading centers produce volcanism under the sea. Question 2 0.5 / 0.5 pts Alberta, Canada response. The attempt with the highest score will automatically be recorded. You may look at your notes and textbook while doing the assignment. Or, to test your knowledge in preparation for the exam, you may want to take the first attempt without the aid of your notes or textbook. Tips For fill in the blank questions please be sure to spell words correctly as you will not receive credit if words are unrecognized or misspelled . Do NOT capitalize words or use commas for fill in the blank questions that require a numeric answer. Why do we care less (and know less) about the hazards associated with volcanism at spreading centers than we do about volcanism at other types of plate boundaries? The following is a region or place on Earth where high population density and abundant active volcanism coincide.

The asthenosphere undergoes heating at the plate boundary. The asthenosphere is saturated with water from the sea floor, causing melting. Question 4 0.5 / 0.5 pts Water interacts with he asthenosphere, causing melting. The asthenosphere undergoes decompression without heating to produce melt. The asthenosphere undergoes heating at the plate boundary. Question 5 0.5 / 0.5 pts The plate remains largely fixed in space, but the hotspot below moves to create the chain. The asthenosphere melts along a line because it is hydrated by the islands. The hotspot remains largely fixed in space, but the plate moves above it to create the chain. The asthenosphere melts along a line because it depressurizes in that geometry. Question 6 3 / 3 pts low viscosity basalt Magmas at mid-ocean ridges are produced by partial melting of the asthenosphere. Why does melting occur at mid-ocean ridges? Melting of the asthenosphere and production of magma at subduction zones is caused by which of the following processes? Why do island chains form near hotspots? Match the characteristic to the type of magma.
