2019/9/19 RockOn #3: GEOSC 10, Fall 2019, Merged 2/17 Basaltic mid-ocean-ridge-type volcanoes. Piled-up mud and other things scraped off the slab being subducted. 正确 ! 正确 ! Slide-past (or transform, with horizontal but not vertical movement) earthquakes and faults. Pull-apart earthquakes and faults. Pull-apart earthquakes and faults often occur at pull-apart basaltic mid-ocean ridges, which are not subduction zones. Slide-past also occurs on the planet, but not primarily at subduction zones, which also are not hot spots. But subduction does lead to scraping of mud off the descending slabs, making piles such as the Olympic Peninsula. 1 / 1 问题 2 Much melting in the mantle occurs near subducting slabs primarily because: Convection cells from the deep mantle rise along subduction zones.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
