      @@Ellensburg44 actually it’s a huge compliment, coming from a bright person who is a woeful teacher as I lack human interactive skills. From clarinet teaching experience, rapport with the students is half the battle, as is having worked hard on technique so better to help students overcome their technical difficulties. Being able to explain the same concept several different ways which you do beautifully is also another important skill

    I caught your comment about shallow subduction near the end of the video, I live in AZ and grew up at the base of the Sierra Estrella Mountains. This range is out of place and time. Modern thinking is that a slab of the Farallon was rotated inland and upended creating this billion y/o range. They do not look like anything surrounding them. I would not dismiss shallow subduction as it does offer explanations to the crazy geology of the American southwest. So crazy that we have "Roof Pendants" ( Four Peaks) that are at 7k+ feet in elevation. Laramide study is exciting :).

  • @annwood6812
    @annwood6812 3 роки тому +3

    I guess my question would be, what happens when a continental plate slides over the East Pacific Rise? If forces are pulling in opposite directions under the continental plate, do these forces affect what's above? Is it warmer if you're right above a spreading zone? I understand the subduction/volcano part. Maybe his next lecture will address this. This guy teaches geology the right way.

  • @franktippin7718
    @franktippin7718 3 роки тому +2

    It seems that the 'Rise is still active as it appears that the continental mas gets weakened enough to break off from the N. American Plate and get added to the Pacific Plate. Are there any estimates as to where under California the stationary E.P. Rise would be sitting right now? Certainly, it isn't still beneath the existing S.A. Fault. If the existing fault was completed about 5ma and assuming the N.P. Plate moves at least 1 inch a year to the west, that would place a stationary rise at least 78 miles further east of the existing fault.

  • @mykofreder1682
    @mykofreder1682 3 роки тому

    I would really like your take on teaching through covid. Midterms are always a time for evaluation and im curious about your thoughts on this topic. Regardless of opinions this black swan event is going to shape teaching going forward. As an old school style teacher before the pandemic (an aspect that i like, respond to, and others do as well), what changes brought on by this do you like and would want to keep? What don't you like, and has to go asap? Class cohesion was bad at the start without meeting in person, and its obvious the first midterm suffered from it. Class size is also a double edged sword. You've been forced to embrace the technology side, with its blessings and curses. Do the recorded lectures stay because students can go back to your actual words over topics they struggle with or classes they miss, or do they go because they create the impression that study groups aren't a requirement anymore, i can always go back to the tape. Im curious on your evaluation of this situation you and the students are forced into, and the shaping education going forwards, with an old school perspective.

    Perhaps you cover this in a newer lesson but I've noticed how you talk about how the Rockies don't fit the normal patterns. Does the fact that the Pacific and farallon plate boundary was a spreading plate have anything to do with forming the Rockies? (Once it went under the North American plate that is)

    @johnnash5118 3 роки тому +3

    I share Nick’s opinion that the JDF axis model should remain stationary, and that the NW Rotation is tied with the Basin and Range mantle mechanics. The evidence is overwhelming.
    Some models are created that assume too much, such as the Farallon/JDF changing its orientation to accommodate the Northwest Rotation. Easy to do on a small scale model, but it ignores how it cannot work with what’s at its margins, such as the rest of the Pacific Plate and its nearly straight as an arrow East-West 2000+ mile long transform faults. Right now, the JDF spreading ridge is positioned in a generally NE/SW axis, corresponding to the Pacific Plate’s NW movement and the Juan De Fuca Plate’s diverging SE movement. Projecting a model as facts to be shared by the esteemed PNSN.org or in a class, over the indisputable sonar image evidence is not science.

    What I think happens to the Farallon Plate is it gets grind up, melted down and spit out into the volcano's like the ghost volcano's which is no-longer being feed the Farallon plate, and like the volcano's that's in Washington, Oregon volcano's, and once all the Farallon Plate gets under and melted down and spit out it becomes a ghost volcano. Just what I think happens to the Farallon plate. It ends up on top of the North American plate as mountains. recycled magma.
