the angle of an object measured in a direction other than parallel to the strike
The apparent dip of a geological plane is the angle of inclination that it seems to have when measured in a direction other than parallel to the strike.
When you can't measure the dip angle directly along the strike direction, you can estimate it in this fashion.
A horizontal line's bearing on an inclined plane
The angle between a geological plane and the horizontal plane, such as a rock layer or fault, is referred to as inclination.
The inclination angle tells us how steeply the inclined plane is inclined with respect to the horizontal when a horizontal line meets it.
It is a measurement of the inclined plane's slope or tilt.
A horizontal line's bearing on an inclined plane
Understanding the orientation of geological features depends on knowing the strike of a geological plane, which provides the compass direction of a horizontal line on the plane's surface.
It is not affected by the plane's inclination and is measured in degrees clockwise from North.
the inclination of an inclined plane measured perpendicular to its maximum slope
When measured perpendicular to a geological plane's highest slope or the direction of steepest descent, such as a rock layer or fault, dip is the angle at which the plane is inclined.
To put it another way, it shows how sharply the plane deviates from the horizontal plane.
the slope's slope angle from the horizontal
The slope angle, which indicates how steeply a geological feature is sloped in relation to a flat surface, is the angle at which the feature is inclined with respect to the horizontal plane.
the horizontal angle between a given coordinate direction (usually north or south) and a certain time
The term "bearing" describes the horizontal angle, expressed in degrees clockwise, between a reference direction (often North) and a particular point or direction.
It frequently provides directional information in navigation, surveying, and other applications.
the orientation of the line-containing vertical plane.
Geologists use the term "trend" to describe the compass direction that a linear geological feature extends along on the horizontal plane.
It's a crucial idea for explaining how rock strata, faults, and other geological structures are arranged spatially.
