The World's Greatest Geological Wonders

Rated 5 out of 5 by from Excellent introductoin to geology I am one of those people who always wants the window seat on the plane and will spend most of the trip with my head glued to the window because I am fascinated by all of the landscapes. I always wonder what could have caused them. This course does a great job of explaining the basic forces that shape our world and answering those questions. I was really only expecting to see some amazing sites from around the world, but professor Wysession uses them to teach about the science of geology and the earth's history. Fascinating!

Rated 5 out of 5 by from Filled with Surprises Dr. Wysession packs an amazing amount of information into each brief lecture, and the lectures add up to a course that is beautifully organized, lucid, and well-illustrated. It takes a special kind of teacher to make such complex material "beginner-friendly," but this is what he has done. I began the course expecting an interesting bit of armchair travel and hoping not to be snowed under by geological jargon; I finished with horizons expanded and mental appetites whetted. I was particularly delighted by the lecture on auroras, the inclusion of out-of-this-world marvels, and the mini-wonders.

Rated 5 out of 5 by from What an amazing planet! Top scores for this fascinating course. Prof. Wysession has put together thirty-six of the most entertaining and fact-filled lectures that I have ever sat through. His excellent choices of photography, animations and bench demonstrations provide clear explanations of plate tectonics, volcanism, glaciation, erosion and the many physical and chemical processes that create features on the planet’s surface. His speaking style is perfect for this subject material. My wife and I have enjoyed about a dozen of the Great Courses ---number theory, differential equations, European painting, Irish history, thermodynamics, organic chemistry, etc. This was the most enjoyable of the lot. Concerning Prof. Wysession’s collection of neckties, I will not comment. HWF, Mesa AZ

Rated 5 out of 5 by from Really loved this course. Roggerio’s commentary wasn’t stuffy at all. Just a joy to learn insider information about art I’ve always loved. There’s mystery behind most art so that’s what makes art history interesting. Thanks so much ❤️

Rated 5 out of 5 by from Fascinating I purchased this course just a few weeks ago and have found it to be a wonderful surprise. This is a subject that I normally do not have a lot of interest in, but I saw the ratings and decided to take something outside of my normal areas of interest. I am so glad I did. I found Mr Wysession to be a terrific instructor, well prepared and with infectious enthusiasm. The visuals are outstanding. I've taken a lot of courses via the "Great Courses", and this certainly ranks up there with the very best.
