Question 10

Tasks

Answer 10

1) Determine flooding risks and co tract topographic profile
2) use stratigraphic column, geologic map, and topographic file to construct cross section do subsurface structure
3) use strike and dip and bed thickness to deter me subsurface folds and vertical distance of a well drilled through rock strata
4) determine order of events based on deformation history and cross cutting relationships
5) asses ego hazard risks based on tectonic setting, seismic history, potential for floods, or slope instability
