Definitions:

Vertical Tension

The force per unit area exerted in a vertical direction within a material, often relating to the stress experienced by geological or man-made structures.

Plunging Anticline

A fold in rock layers that slopes downward from the crest, usually indicating compression forces within the Earth's crust.

Asymmetric Anticline

A geological fold that is not symmetrical about its axis, indicating differential movement or deformation.

Horizontal Syncline

A geological fold with layers that dip towards the center from both sides, and typically have a horizontal or nearly horizontal axis.
