Determine the angle of dip
                    If the contour lines are at very large distance to each other, this indicates a ____slope
                  
                  
                  
                    The distance measured perpendicular to the upper and lower contact of a tabular unit
                  
                  
                  
                    The distance on the map between the bounding contacts of a tabular unit measured along an azimuth perpendicular to strike
                  
                  
                  
                    Geologic graphics help determination of the geology of an area comprising of the rock formations, their thickness and sequence above or below the ground surface. (Say True or False)
