If rock strata are tilted in some way, a geologic map shows the tilted rock with strike-and-dip symbols. These symbols indicate the orientation of the rock layers, specifically the direction of the strike (the line formed by the intersection of a rock layer with a horizontal plane) and the angle of dip (the angle at which the rock layer inclines relative to the horizontal plane).
The law of original horizontality suggests that rock strata are always layered in a horizontal plane. If rock strata are tilted in some way, a geologic map shows the tilted rock with _____.
fault line symbols
fold axis symbols
letter symbols
strike-and-dip symbols
