GEOLOGY

Detailed explanation-1: -Earthquakes occur along faults, which are fractures between blocks of rock that allow the blocks to move relative to one another. Faults are caused by the bumping and sliding that plates do and are more common near the edges of the plates.

Detailed explanation-2: -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. Strike-slip faulting is associated with lateral motion of the crust, and so can be found at transform boundaries.

Detailed explanation-3: -Faults are cracks in the earth’s crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. If tension builds up along a fault and then is suddenly released, the result is an earthquake.
