Question

On a geologic map, strike represents the directional orientation of a fault.

Answer 1

Answer:

The statement that says 'on a geologic map, strike represents the directional orientation of a fault' is false.

Explanation:

• If it is considered that the given geologic map is of a horizontal plane, then the 'direction of the rock' present on this horizontal plane would be represented by a strike on the given geologic map.

• To represent a fault on the 'geologic map', the symbol of a thick line inclined towards the right is used.

Answer 2

This is TRUE

Strike is a way of representing the 3D orientation of a planar surface on a 2D map. Fault can be characterized by brittle deformation in rocks. These faults can be oriented at any direction (Strike). Shear stresses can produce faults where movement can occur in strike direction.
