Geology 8 (Weathering and Erosion)

This lecture video covers the two different types of erosion (physical and chemical) and explores the impact it has on rocks and landscapes. I hope you enjoy it! Closed captioned.

I have a midterm tomorrow -I have never been more grateful to find such good lectures!

Absolutely liking all these charts, never seen them in any of my many other geo courses. Makes immediate sense.

Excellent lecture. It's refreshing to hear someone genuinely excited by their topic/area of expertise. It's infectious too. I smiled a lot listening

[jeffbrunswick]

Yet another fantastic lecture. You are really wonderful at explaining things. Thanks so much.

Another morning, another lesson. Thank you again.

I started off studing gemology but have taken a turn to study geology. I love your videos. They are informative and presented extremely well. Thank you.

This is a great series and this lecturer does a great job. Bravo!

These series of lectures are helping to answer the natural questions I came up with to myself on my global travels. Outstanding. Living in Japan there are always so many interesting geological questions! Well done!

I majored in geology 50 years ago. I’ve been away from it. This series is great!

[Bloodknok]

These are a really great series - I’m watching each in sequence and learning some interesting facts

[ABettle]

very amazing lecture, completely fascinating and thanks so much for doing this lecture i learn so much from u and would like it if u made more like this

[madelynhughes]

Thanks! your lectures are getting me through earth science!!!

2:40- very common roadside terrain often seen enforced by sloping covered by a concrete layer. But that may not have stopped this slide given the massive backdrop soil cliff.

It is very helpful and interesting. Thank you very much for your great effort..

New very basic physical weathering force recently discovered! - heating of rocks on hot days causing enough expansion to crack rock, similarly to frost wedging. Study in Yosemite found that significantly higher number of rock avalanches happened after hot days. That exfoliating video is thought to be an example of this.

The image at 1:30 shows a landslide that occurred in northern Taiwan in 2010 after a lot of rain.

Thank you sir
Very precious information

Could you do a lecture on Karst, caves and sinkholes? Or would that fall under the erosion lecture? Thank you.

When I go hiking, sometimes my trekking pole hitting the rock (usually granite) makes a reverberating hollow sound. The sound is just like the sounds I was hearing in your live exfoliation video. Do you think the hollow sounds I’m hearing are the same thing? Voids left under the layer of rock I’m standing on due to exfoliation? Not active crack forming or anything, but am I standing on a sheet of rock that is loose and slightly floating above a sheet below?

Great Videos Sir.Please explain igneous and ore geology in your next videos too.Thnx
