GEOLOGY

Detailed explanation-1: -Earthquakes originate in Benioff zones, zones that slope downward from the trenches and under the overlying rocks at 30 to 60 degrees. Benioff zones are closely associated with the subduction of a crustal plate below an adjacent plate. Almost all earthquakes occur at the edges of the crustal plates.

Detailed explanation-2: -Plate Boundaries In addition, each type of boundary is associated with particular geologic activities, like earthquakes and the creation of mountains and volcanoes. Most earthquake and volcanic activity occurs along or near plate boundaries.

Detailed explanation-3: -Seventy-five percent of Earth’s volcanoes-more than 450 volcanoes-are located along the Ring of Fire. Ninety percent of Earth’s earthquakes occur along its path, including the planet’s most violent and dramatic seismic events.

Detailed explanation-4: -Most earthquakes and volcanoes happen at plate boundaries because in between plates there is a lot of activity, meaning tectonic plate movement (convection forces that rock deformation and construction of faults and fractures).

Detailed explanation-5: -The plates rip apart at divergent plate boundaries, crash together at convergent plate boundaries, and slide past each other at transform plate boundaries. Tectonic activity such as earthquakes, volcanic eruptions and the formation of mountain ranges commonly occurs along the boundaries of the moving plates.
