Metamorphic rocks.
Usually it is metamorphic rocks that are formed by heat and pressure, but sedimentary rocks can too. Usually, the word 'sedimentary' means 'of sediments' which means that it is composed of lots of layers upon layers compacting down. In that case, pressure is essential, but heat isn't always needed.
mudstone and shale. These can become the metamorphic rock slate if exposed to high pressure and temperature.
An igneous rock, just like any other rock, can be changed through metamorphic, igneous, and/or sedimentary processes. When exposed to high temp. and pressure, igneous becomes metamorphic. When re-melted, it becomes igneous again. When weathered/eroded, it becomes sedimentary.
Sedimentary rock formation begins with igneous, metamorphic, or other sedimentary rocks. When these rocks are exposed at the earth's surface they begin the long slow but relentless process of becoming sedimentary rock.
It would undergo metamorphism, if the heat and pressure are sufficient.
Sedimentary rock that is exposed to heat and pressure will be changed to (metamophised) into metamorphic rock. This is often associated with volcanic activity. An example is limestone, when exposed to the pressure and heat can be changed to marble.

Metamorphic rocks.
Sedimentary rocks, when exposed on the surface, is exposed to weathering.
By them being boroken down (sediment) then exposed to great pressure.

when sedimentary rocks get exposed to great heat and pressure, they become more consolidated (harder to weather). when igneous rock combines with sediments and the two are heated under pressure, they become one rock, a metamorphic rock
