Classification of Faults MCQs : Here you will find MCQ Questions related to "Classification of Faults" in Engineering Geology. These Classification of Faults 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.
How many types net slip faults has?
Explanation: On the basis of net slip faults have the following three types : Dip Slip Fault, Strike slip fault, Oblique slip fault
The faults in which the slip takes place along the direction of the slip is called?
A. Dip slip fault
B. Strike slip fault
C. Oblique slip fault
D. Normal fault
Explanation: The faults in which the slip takes place along the direction of the slip is called dip slip fault in the dip slip fault net slip is parallel to the dip of fault.
Reverse faults with very shallow dipping fault planes (<10 degrees) are called?
A. Normal fault
B. detachment faults
C. thrust faults
D. Low angle fault
Explanation: Reverse fault is one in which the hanging wall moves up relative to the foot wall due to compression. If the hanging wall is pushed up and then over the foot wall at a low angle it is called a thrust fault. Reverse faults with very shallow dipping fault planes (<10 degrees) are called thrust faults.
A series of faults running more or less parallel to one another and all handing in the same direction, are called?
A. Parallel fault
B. Step fault
C. Graben or Rift fault
D. Radial faults
Explanation: A series of faults running more or less parallel to one another and all handing in the same direction, are called parallel faults.
Which type of classification emphasises on appearance?
A. Based on direction of slip
B. Based on apparent movement
C. Based on mode of occurrence
D. Based on mode of occurrence
Explanation: The emphasis in the case of faults based on apparent movement as basis is only on appearance because actually it may require to be established which of the two parts, hanging wall and the foot wall, has moved during faulting and by how much.
Horsts and grabens are believed to occur due to ___________
A. Lateral compression
B. Shear compression
C. Lateral tension
Explanation: The origin of horsts and grabens is believed to be due to lateral tension in the crust in most cases
The phenomenon not associated with imbricate structures is ___________
A. Series of thrust blocks occur in close proximity
B. Thrust blocks are piled up one above another
C. All fault surfaces dip in the same direction
D. Thrust blocks aren’t piled up one above another
Explanation: When a series of thrust faults occur in close proximity, thrust blocks are piled up one above another and all the fault surfaces dip in same direction. The resulting interesting structure is known as an imbricate structure.
The fault not belonging to the classification of fault with the attitude of fault as basis ___________
A. Heave fault
B. Strike fault
C. Dip fault
D. Oblique fault
Explanation: The mutual relationship of attitude of fault and of the disrupted rock has also been used in some cases for classifying faults into three types: dip faults, strike faults and oblique faults.
Most common angle of normal faults is 45° to vertical.
C. Can be true or false
D. Can not say
Explanation: In normal faults, the fault plane may be inclines at any angle between horizontal and vertical, but most commonly, the fault angles are between 45° and vertical.
What does the reverse fault cause to the crust of the Earth?
A. Extension of the crust
B. Strengthening of the crust
C. Weakening of the crust
D. Shortening of the crust
Explanation: By virtue of their inclination and direction of movement, reverse faulting involves shortening of the crust of the crust of the Earth (compared with normal faults).
