What is the apparent dip of a bed? - correct answer Apparent dip of a bed or plane is the inclination of that bed or plane in a direction not perpendicular to strike. What is a fold line and how is it used? - correct answer The fold line is a hinge line along which a vertical cross section may be constructed and then flattened out to a horizontal or map view. It is used to represent the subsurface along any given line in a map view. It need not be perpendicular to strike. What is the a...
