What makes a typical shear zone different from a typical fault?

What will be an ideal response?


Ans: A shear zone is wider relative to the offset, it has maintained cohesion, markers are still (mostly) continuous for most shear zones (ductile shear zones), they do not show a core–damage zone anatomy, and most shear zones involve plastic deformation mechanisms.

An elevator has a rated capacity of 2,000 pound mass (907 kg). It can transport people at the rated capacity between the first and the fifth floors in 7 seconds with a vertical distance of 15 ft (4.6 m) between each floor. Estimate the power requirement for such an elevator.
