Burial
Two types of metamorphism occur in earth's crust. One is when small volumes of rock come in contact with magma. And the other is when large amounts of the earth's crust are effected by heat and pressure
When tectonic plates move and grind against each other, this is an earthquake. If the moving of tectonic plates were to occur beneath the ocean's surface, the result would be a tsunami.
The short answer is that they don't! For metamorphism to occur rocks require either heat, pressure or a combination of the two. Both of these conditions occur together in the mantle, however they can occur in other places to. Such as in the rocks around igneous intrusions (high temperatures and low to moderate pressures) which cause contact metamorphism. It can also occur in zones of high tectonic stress (such as continental collision zones where mountains are being built where there is a relatively low temperature by mantle standards but very high pressure) which causes regional metamorphism. Finally in zones characterised by very high strains (e.g. the rocks in very close proximity to fault zones) metamorphism can occur. The type depends on the strain rate and the depth (which affects the pressure and temperature). This type of metamorphism is known as dynamic metamorphism). All the above conditions (and a number of others) can cause metamorphism to occur in sections of the earth outside the mantle. The differing types of metamorphism at differing temperatures and pressures create differing assemblages of minerals. These are known as metamorphic facies.
