|
|
|
seismic gaps and shadow zones form there
|
|
|
very little rock stress and strain occur there
|
|
|
intense stress occurs there when the plate separate, collide, subduct, or slide past each other
|
|
|
they have a long geologic history of occurring in the same place

Detailed explanation-1: -A fault is formed in the Earth’s crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this.
Detailed explanation-2: -The third type of plate boundary occurs where tectonic plates slide horizontally past each other. This is known as a transform plate boundary. As the plates rub against each other, huge stresses can cause portions of the rock to break, resulting in earthquakes. Places where these breaks occur are called faults.
Detailed explanation-3: -When two plates come together, it is known as a convergent boundary. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench.
Detailed explanation-4: -Normal faulting is associated with crustal extension, and so can be found at divergent boundaries. Reverse faulting is associated with crustal shortening, and so can be found at convergent boundaries.
