sir, use diagrammatic representation to explain folding and faulting. it gets easier to understand.
please do continue geography optional courses
Please insert diagrams, it speaks hundreds of words. also pointing out the examples ( black mountains) on the world map will seal the info on learner's mind.
Nice course... lucid explaination... But need pictorial representation for conducive understanding...
