Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Where do strike slip faults occur mostly?
A
Convergent boundaries
B
Transform boundaries
C
Divergent boundaries
D
None of the above
Explanation: 

Detailed explanation-1: -Strike-slip faults are widespread, and many are found at the boundary between obliquely converging oceanic and continental tectonic plates.

Detailed explanation-2: -Strike slip systems are relatively narrow and subvertical wrench zones along which two adjacent blocks move sideways, horizontally, parallel to the strike of the fault zone. For example, they are produced at transform plate boundaries where plates horizontally slide past one another.

Detailed explanation-3: -c) Transform Plate Boundaries Because rocks are cut and displaced by movement in opposite direction, rocks facing each other on two sides of the fault are typically of different type and age. These structures are so-called strike-slip faults.

Detailed explanation-4: -Most transform boundaries are associated with the spreading spreading centers at mid-ocean ridges . They occur near these divergent boundaries because the spreading rate changes along a ridge.

Detailed explanation-5: -Strike-slip faulting is associated with lateral motion of the crust, and so can be found at transform boundaries.
