The duration of the dip tells the size of the planet, and the time between the light dips tells the length of the planet's orbit.

This paper analyzed the influence of mining depth, coal seam dip, mining height and face length on depth of floor water-conductive fissure zone.

In this paper, a method is proposed such that the strike, dip, dipping direction and fracture length of a fault plane can be determined using of isoseismal lines.
