Rock can be changed into metamorphic rock by heat and pressure.
The rock that gets heat+pressure to turn into a metamorphic rock.
No, rock does not melt when it is changing into metamorphic rock. Metamorphic rocks form from pre-existing rocks, such as sedimentary or igneous rocks, through a process called metamorphism. This process involves changes in temperature, pressure, or the presence of fluids, which cause the minerals in the rock to recrystallize without melting.
Changing pressure and temperature can transform sedimentary rock into metamorphic rock. This process involves the recrystallization of minerals in the rock due to intense heat and pressure, creating a new structure and texture.
A metamorphic rock is formed when sedimentary rock is subjected to heat and pressure!
The heat comes from Earth's interior, which is always hot.

A metamorphic rock is made when an igneous or sedimentary rock undergoes heat and pressure for many years, changing it into another type of rock.
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
A gneiss is a metamorphic rock. Metamorphic rocks are created by the alteration of rocks by heat and pressure. Therefore, a gneiss may be created from an igneous rock in which case it would be called an orthogneiss.
