=Definition=
The orientation of a rock bed, fault, fracture, cuestas, igneous dikes, and sills can be described using strike and dip of the rock. Strike is direction of the line formed by the intersection of a fault, bed, or other planar feature and a horizontal plane. Strike indicates the attitude or position of linear structural features such as faults, beds, joints, and folds. Dip is the angle at which a planar feature is inclined to the horizontal plane; it is measured in a vertical plane perpendicular to the strike of the feature.<ref>http://www.britannica.com/science/strike-geology</ref>
