GEOLOGY

Detailed explanation-1: -The grinding action between the plates at a transform plate boundary results in shallow earthquakes, large lateral displacement of rock, and a broad zone of crustal deformation. Perhaps nowhere on Earth is such a landscape more dramatically displayed than along the San Andreas Fault in western California.

Detailed explanation-2: -Transform boundaries typically produce large, shallow-focus earthquakes. Although earthquakes do occur in the central regions of plates, these regions do not usually have large earthquakes.

Detailed explanation-3: -About 80% of earthquakes occur where plates are pushed together, called convergent boundaries. Another form of convergent boundary is a collision where two continental plates meet head-on.

Detailed explanation-4: -A transform fault is a plate boundary along which the relative motion between the two plates is parallel to the strike of the fault and is geometrically the arc of a small circle about the pole of rotation between two plates.

Detailed explanation-5: -An example of a transform-fault plate boundary is the San Andreas fault, along the coast of California and northwestern Mexico. Earthquakes at transform faults tend to occur at shallow depths and form fairly straight linear patterns.
