    Free knowledge is more valuable than gold. Thank you Professor
  • I love YouTube. And Shawn Willsey for your willingness to do this. I am 81 and for the last 30 had the opportunity to travel around the US in a Motorhome. I saw so many things I did not understand. Did that rise, was that formed by erosion, how did those layers get up there, why are those layers at that angle? and on and on. I recently discovered your videos and appreciate your effort to teach us. I will thoroughly enjoy the series and look forward to learning more about the tectonic plates. I travel up and down the Owens valley/ Eastern Sierra each year and try to learn more about what is there. Thank You.
  • Thanks! Sean, I’m 15 minutes into this first episode and am paying forward for my and my wife’s participation in this pending series. You have a gift in how you convey knowledge that we appreciate.
  • I was in college in the 1970s, I remember plate techtonics being presented as a new theory rather than established fact so am looking forward to how you cover that now 50 years later. Thanks for the content 👍

    Shawn, thank you for taking the time to educate us . Your teaching style is amazing. You make it easy to understand and learn.
  • @muzikhed
    Excellent new creation. Looking forward to following this new series.
  • @stevendente9270
    This should be a great series. I majored in Geology in the 1970. My work in it has brought me 5o years of an enjoyable and fascinating life. I wish I had a resource like this in High School when my interest in Earth Science formed. Keep up the great work.
  • @marypulford6213
    WOW. Learned more from this first video ……. Looking forward to the next episode
  • This will definitely assist in understanding the Iceland updates on how the processes work. Thank you for making this series.
  • Thanks very much for this series! I grew up in the Black Hills of South Dakota and have been interested in geology for as long as I can remember. I took Earth Science in high school, but majored in a different physical science in college. But still love geology as a 76 year old. I remember looking at the world map in grade school and thinking about how South America and Africa looked like they would fit together, and then years later when the concept of plate tectonics was introduced, thinking , Well, duh! That makes lots of sense!" So glad to have this opportunity to learn all the most recent concepts and theory about geology!

    Couldn’t find a similar class locally, so I am very excited and grateful that you are presenting this knowledge online. My “qualifications” for this journey: Retired English teacher, psychology major in college (experimental or “rat” psychology back in the 1960s), quilter, knitter, crocheter, seamstress, grandmother, lifelong learner, lover of elephants and eagles, avid reader and YouTube fan… The world has certainly changed in my lifetime, and generosity like yours is not easy to find. Thank you, professor!
  • @BeateHerold
    I had always thought that geology is a boring subject. But with you, being such a good teacher, it is not! Thank you so much for this new series, Shawn!
  • @vhhawk
    15:00 asthenosphere .. I did not expect to learn something new in the intro. Wow.
  • Thanks, Shawn, for the content you are sharing with us. Excellent presentation. Your enthusiasm for your subject is infectious and you always leave us wanting more. Looking forward to following your series.
  • @Angie-pl3uw
    Fabulous! Who would‘ve thunk this English major might be the slightest bit interested in geology? Thank you, Professor Willsey.
  • @raenbow66
    I'm always on board for learning! Thanks so much, Shawn!! 13 y.o. grandson watching, too!
  • @brendanacord
    This. Just watched this with my young son and he had me pause multiple times to ask some great questions. Thanks Shawn!
