∙ 11y agoThe three main types of metamorphism are:
Regional Metamorphism
Contact Metamorphism
Hydrothermal metamorphism
Regional metamorphism is caused when high temperature and pressure affect large regions of Earths crust, It can range from low grade to high grade. It causes folded rock layers.
Contact Metamorphism is when molten material comes in contact with solid rock. High temperature and moderate to low pressure from mineral assemblages. Metamorphic effects decrease with distance.
Hydrothermal Metamorphism is when very hot water reacts with rock and alters its chemical and mineral composition. As hot fluids migrate in and out of the rock during metamorphism the original mineral composition and texture of the rock change.

∙ 11y agoContact metamorphism does not cause profound compaction, which is the reduction in size of the spaces between mineral particles due to increases in pressure. Regional metamorphism causes compaction and possibly recrystallization, increasing the density of the rock.

=== === Metamorphism does not cause a rock to melt. If a rock melts, then solidifies, it is by definition an igneous rock. There are rocks called granulites which represent the highest grade of metamorphism, and some may have experienced a partialmelting.
factors that cause weathering are erosion and water
Basaltic magma
CAUSE THERE GAY
contact and regional metamorphic are similar because both of them happen cause of hot heat and pressure which make the rock metamorphic
