When heat and presure are applied to a rock what kind of rock results?

Exposure to intense heat and/or pressure can result in changes to a rock's mineralogy, crystal structure, and mineral alignment. Such changes can create a metamorphic rock.


Do the changes in rocks due to heat and pressure result in the formation of metamorphic rocks?

Yes. A rock is said to be metamorphosed when it undergoes a change due to heat and/or pressure.

What type of rock forms when heat and pressure change one type of rock into another?

Changes in the structure, texture, or mineralogy of existing rocks will create a metamorphic rock. Metamorphism can result from the effects of heat and/or pressure, or from the addition of ions from heated fluids. Examples of metamorphic rock are slate, schist, and gneiss.


What is the process called where igneous sedimentary or metamorphic rocks are changed by heat or pressure?

Your question contains part of the answer, 'metamorphic' rocks are the product of this process and the process is called Metamorphism - the solid-state recrystallization of pre-existing rocks as a result of changes in heat, pressure, and/or introduction of fluids.
