These Fault Terminology MCQ Questions Will help you to improve your Engineering Geology knowledge and will prepare you for various Examinations like Competitive Exams, Placements, Interviews and other Entrance Exmaniations.
If the dip angle is less than 30 the fault is called?
A. low-angle fault
B. steep faults
C. thrust faults
D. listric fault
Explanation: If the dip angle is less than 30 the fault is called a low-angle fault, while steep faults dip steeper than 60 .
A fault that ﬂattens downward is called?
B. listric fault
C. master faults
D. synthetic fault
Explanation: A fault that ﬂattens downward is called a listric fault, while downward-steepening faults are sometimes called antilistric.
Normal faults dipping away from each other create an up thrown block called a?
C. net slip
Explanation: Normal faults dipping away from each other create an up thrown block called a horst.
___________ is the separation of layers observed on a horizontal exposure or map
A. Cut off separation
B. Dip separation
C. Horizontal separation
D. Line separation
Explanation: Horizontal separation is the separation of layers observed on a horizontal exposure or map, while the dip separation is that observed in a vertical section.
What is the key word in the definition of fault?
C. Both fracture and movement
Explanation: The key words in the definition are fracture and movement. The exact significance of these key words must be clearly understood.
A fault has how many walls?
Explanation: In faults, the concept of walls is very important and must be understood very clearly. In a rock body, when a fracture takes place, it divided the rock into two parts or two blocks.
Heave is _______
A. Horizontal component of dip separation
B. Vertical component of dip separation
C. Normal horizontal displacement measured
D. Signifying separation between two beds
Explanation: Heave is the horizontal component of dip separation measured in a direction perpendicular to the strike of the fault in a vertical plane.
Faulting is a _________ process.
C. Both tectonic and non-tectonic
Explanation: Faulting is a major tectonic process of great geological importance. The geological history of the Earth bears innumerable events recording in the script of folding, faulting and jointing.
What is the block which suffer displacement in faulting called?
Explanation: The blocks which suffer displacement and stand on either sides of the fracture are called as walls. Generally there exist two types of walls, hanging wall and foot wall.
What signifies the actual separation between two beds?
D. Stratigraphic throw
Explanation: Stratigraphic throw signifies actual separation between two beds with a known stratigraphical position in a sequence of rocks that are now brought into contact by faulting
