Metamorphic rocks are produced by intense heat and pressure on pre-existing rocks.
produced by volcanic action or intense heat
The rock becomes a metamorphic rock

Metamorphic rock is formed when Igneous rock and Sedimentary rock go through intense heat and pressure.
Sedimentary rocks when altered by heat and pressure because metamorphic rock. But please read the rock cycle you will see the different stages because Igneous can also become Metamorphic with intense pressure and heat.
If you apply shale with intense heat and pressure. you'll get slate. Now just apply intense heat and pressure to the slate an over time you'll get your schist
The thicker the bands the more intense the heat and pressure conditions were to form the rock. Metamorphic rocks are transformed existing rock types. Thicker bands in the appearance of a metamorphic rock mean that it was made with more intense heat and under greater amounts of pressure.
