GEOLOGY

Detailed explanation-1: -Normal Faults: This is the most common type of fault. It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming.

Detailed explanation-2: -Normal, or Dip-slip, faults are inclined fractures where the blocks have mostly shifted vertically. If the rock mass above an inclined fault moves down, the fault is termed normal, whereas if the rock above the fault moves up, the fault is termed a Reverse fault.

Detailed explanation-3: -A normal fault forms as a result of tensional stress, which occurs when two blocks of rock move away from one another. These types of faults form along divergent boundaries, which are boundaries where two tectonic plates separate from one another such as those found at seafloor ridges.

Detailed explanation-4: -Shallow, low-magnitude earthquakes commonly occur at divergent plate boundaries. Earthquakes at divergent plate boundaries are distributed with predictable locations and depths. Earthquakes at divergent plate boundaries occur as new crust is created and other crust is pushed apart.
