two yellow lines have been drawn on the above picture by the instructional team. these lines follow an interesting surface. this surface is: group of answer choices a great unconformity, with sedimentary rocks above resting on younger sedimentary rocks below. a great fault, where pull-apart death-valley-type faulting dropped rocks so that they could be preserved from erosion and seen today. a great unconformity, with sedimentary rocks above resting on older sedimentary rocks below. a great unconformity, with sedimentary rocks above resting on igneous and metamorphic rocks below. a great fault, where push-together action shoved the upper rocks over the lower ones.
