Final answer:
Contact metamorphism typically occurs near hot springs due to the geothermal heat, while regional metamorphism commonly occurs in subduction zones where oceanic plates are subducted under continental plates.
Step-by-step explanation:
Metamorphism primarily occurs in mountain belts or ancient mountain belts, where there is a significant change in temperature and pressure due to tectonic activities. Specific conditions for contact metamorphism, which is one type of metamorphism, include the heat from the intrusion of a large igneous mass, such as a magma chamber or when rock layers come near hot magmatic bodies. The correct answer to where contact metamorphism occurs is c) Near hot springs, as these are areas where geothermal heat can alter the surrounding rocks.
Another type of metamorphism, regional metamorphism, typically occurs in subduction zones where oceanic plates subduct beneath continental plates leading to high temperature and pressure conditions. The repeated cycle of material being added at rift zones and subducted at subduction zones plays a crucial role in the mineralogical and textural changes that define metamorphic rocks.
