Quizplus · Accepted Answer

Contact metamorphism is caused by the close proximity of a magma source. The intense heat and pressure from the magma alter the surrounding rocks, forming new minerals and changing their texture without actually melting them. Dynamic metamorphism is caused by the crushing and shearing of rocks under tectonic stress, while regional metamorphism is caused by the effects of high pressure and temperature over a large area, typically in a mountain-building or subduction zone setting.
