GEOLOGY

Detailed explanation-1: -Earthquakes occur along fault lines, cracks in Earth’s crust where tectonic plates meet. They occur where plates are subducting, spreading, slipping, or colliding. As the plates grind together, they get stuck and pressure builds up. Finally, the pressure between the plates is so great that they break loose.

Detailed explanation-2: -When two tectonic plates meet, we get a “plate boundary.” There are three major types of plate boundaries, each associated with the formation of a variety of geologic features. If two tectonic plates collide, they form a convergent plate boundary.

Detailed explanation-3: -A fault is a fracture or zone of fractures between two blocks of rock. During an earthquake, the rock on one side of the fault suddenly slips with relative to the other. The faults are most commonly found around the edge of plates which are continental-size blocks of rocks that comprise the outermost part of the earth.

Detailed explanation-4: -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. Faults have no particular length scale.

Detailed explanation-5: -A subduction zone is the biggest crash scene on Earth. These boundaries mark the collision between two tectonic plates.
