Glacial Landforms

Ғылым және технология

In this video we review the principal landforms created by glacial erosion (cirques, arêtes, striations, U-shaped valleys, fjords) and deposition (till, moraine, drumlins, eskers, kettle lakes, outwash plain, erratics). We discuss how a pair of glacial erosion processes - plucking, abrasion - work to break down rocks and modify the landscape. We compare and contrast glacial deposits made up of an unsorted mix of clay, sand and boulders and those that have been generated by running water. Finally, we start and finish the video by trying to figure out how a giant boulder ended up jammed in among the trees in Yellowstone National Park. The video ends with a short review quiz that asks you to identify four images of different landforms.

    I have several of these features on my property here in Skåne Sweden. I love the place living here in this otherworldly landscape now covered in trees. I've described these to my guests all the time as we walk along the eskers. Natives of Sweden who live here are unaware of what's around them. I'm an American living among them for a decade now. I knew there had to be a name to these awesome deposits from the outfall of a mullin, these are the highest points on my property!.. I was so excited to find the name of this formation from this video I "kame" ;-P thanks!

    Wow thank you so much for this video. The pictures and explanations of these different landforms has really helped me understand what they are and pick them out on a landscape better.

    Beautiful video. Sharp, crisp, to the point. Images are excellent to make someone understand these landforms who may have no earlier idea of geology. Well done!

    Thank you! Why it's so good when two different voices are explaining a concept? Each time I watch a video done in this manner I remember theme better - atleast I'm under impression that that's true.

    Nice, Very informative. Thank you for posting this. I got Moraine, Cirque, Kettle right. Totally blew Till. I don't think I will ever forget "till" again. Could you or if you did or someone else you know has done, I would like to know more about the Glacier that went through north central ohio. Avon to Sandusky south would be wonderful. Thank you.

    The "striations" found in limestone in Ohio could not have been carved by ice, as they are demonstrably turbulent erosion features. Ice is too viscous to move turbulently, so the features are better interpreted as erosion marks carved by turbulent subglacial vortices in water.

    Being 80 and living in the adirondack mountains and found 3 Rhyolite volcanos with no place higher from here to hudson bay and this is in yellow stone national park. If you are not a geologist you will figure it out. I found the volcanos because of my forestry training and to find gold. Red pine trees and schoch pine trees are not native to the U.S. the CCC camp planted tree in the adirondacks for 8 years to see some thing different on a you tube channel watch century new technologies company inc start at the third from the last movie to where mother nature plugged up plum brook
