“2. Graduates will understand Earth surface processes and how humans affect and are affected by the processes. (Examples, sedimentary systems, interaction of earth surface with oceans and atmosphere, geomorphological processes, climate and climate change, environmental geology.)” Assessment tools are in the form of quiz/exam questions, listed below: 1) What can we look for in a sandstone to tell us whether it was deposited in a coastal/beach environment or a desert/dune environment? 2) In a transgressive sequence (rising sea level), would you expect to see sandstone on top of shale and limestone, or limestone and shale on top of sandstone? Explain. 3) A sequence is a group of rocks that represents one cycle of sea level change. What feature would you expect to see between rock sequences, that marks the transition from high sea level to a drop in sea level? (hint: NOT what rock type, but what geologic feature that represents a change from transgression to regression). 4) Below is a cross-section of the Grand Canyon stratigraphy and its corresponding geologic time. Would you expect to find more fossils in the Unkar Group or the Tonto group and why? Immediately after the erosion event that created the great unconformity (angular unconformity between Unkar Group and Tonto group), was there a transgression or regression of the ocean, and how do you know? 5) When Earth first formed it did not have an atmosphere. Where did the gasses in the earliest atmosphere come from? How was the Archean atmosphere different from Earth’s atmosphere today? 6) How would a fluvial (river channel) deposit be different from a delta deposit? (Discuss grain size, shape, sorting, and lithology).
