Which special symbol is commonly used by geologists to describe the orientation of rock beds, faults, fractures, cuestas, igneous dikes and sills?​

Correct option is C

Correct Answer: Strike and dip

Explanation:
Geologists commonly use the strike and dip symbol to describe the orientation of rock beds, faults, fractures, and geological features like cuestas, igneous dikes, and sills.

• Strike represents the direction of a horizontal line along the rock layer.
• Dip is the angle at which the rock layer slopes downward from the horizontal plane.
  This symbol provides vital information about geological structures and their alignment.

Information Booster:

·         Strike and dip are fundamental in structural geology.

·         Helps in interpreting tectonic forces and geological history.

·         Essential for creating geological maps and cross-sections.

·         Strike is measured using a compass, while dip requires an inclinometer.

·         Widely used in mining, petroleum exploration, and geological surveys.
