Lecture 4: Faults and folds-models of deformation

[@malakdaim6437]

Excellent video. I can't wait to show my students!

[@fingerofthomas]

I have a question. Folds DR Butler demonstrated are with flexible papers, not solid/concrete rocks. could you explain why all the layers could fold together without breakage?

[@ishanmishra9383]

That's because folding occurs over millions of years. High temperatures coupled with slow deformation rates leads to ductile behaviour.

[@arunabhanaskar27]

Depends on the ductile & brittle behaviour of rocks... Subsurface conditions gradually change from brittle to ductile as we go deep inside the Earth...

[@poetryph6258]

Perfect way to demonstrate the faults, folds etc.....thank u so much sir....

[@Tamaslammer]

Thanks Doc! I stumbled onto this and now I know the 3 types of stress on the Earth's crust.

[@aminshah4891]

awesome demonstration.

[@adibanajmul4461]

Kindly help me out to make a demonstration model of the movement of tectonic plates

[@garundip.mcgrundy8311]

The jerks are episodic. Sedimentation, too, is episodic within the context of a single larger catastrophic event.

What is the difference between Rift and Graben ?
