Question
The direction of a horizontal line on an inclined rock strata is known as :
The correct answer is
Strike
Strike: Horizontal Line Direction
The term describing the direction of a horizontal line on an inclined rock strata is known as the strike.
Understanding Geological Terms
In structural geology:
- Strike: This is the compass direction of a line that lies perfectly horizontal on an inclined geological surface (like a rock layer or fault plane). It is perpendicular to the direction of the dip.
- Dip: This is the angle measured downwards from the horizontal plane, representing how steeply a rock layer is inclined. The direction of dip is perpendicular to the strike.
- Anticline: This refers to an upward-arching fold in rock layers, forming a ridge-like structure.
- Syncline: This refers to a downward-arching fold in rock layers, forming a trough-like structure.
Therefore, the direction of a horizontal line on inclined strata is the strike.
