Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
Metamorphic rocks at hot spots will form mostly by contact and hydrothermal metamorphism as a result of exposure to heat from magma and interaction with hot water respectively.
Metamorphic rocks form when existing rocks undergo changes in temperature and pressure due to processes such as tectonic plate movement, burial deep within the Earth's crust, or contact with hot intrusions. These changes cause the minerals in the existing rocks to recrystallize and reorganize, leading to the formation of metamorphic rocks.
Igneous, metamorphic, and existing sedimentary rocks can weather and erode to form sedimentary rocks. Igneous and metamorphic rocks can break down into sediments through processes like weathering and erosion, which then may accumulate and lithify into sedimentary rocks. Existing sedimentary rocks can also be reworked and lithified to form new sedimentary rocks through processes like compaction and cementation.

False. Metamorphic rocks can form from igneous, sedimentary, or other metamorphic rocks through processes such as heat, pressure, and/or chemical activity. The rock's original composition and mineralogy can change during this process.

The metamorphic processes of heat and pressure can alter the parent rock (sedimentary, igneous, metamorphic) chemically or structurally into a form of rock that can only be created under certain conditions. Metamorphic rocks are not created from sedimentation and lithification or from molten material.
Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.
