the deeper into earth crust the higher the pressure that forms metamorphic rocks

Antarctica is a large continent and as such has a lot of different rock formations incorporating igneous, sedimentary and metamorphic rocks.
High pressure can cause the formation of the metamorphic rock slate from the sedimentary rock shale.

Igneous rocks are formed in and around volcanos, metamorphic rocks are formed by the partial melting of rocks deep underground.
The metamorphic rock would be older, because in the sedimentary rock's formation that is caused by collected sediment taking years to harden and turning into a rock, the metamorphic rock would have already been considered metamorphic when traces of it came into the sedimentary.

Heat and pressure are responsible for the formation of metamorphic rock.
Rock formation is categorized into 3 different groups:sedimentary,igneous, & metamorphic.
the deeper into earth crust the higher the pressure that forms metamorphic rocks
Yes. That is the basis of the classifications. === ===
temperature, pressure or added fluids

No rock was originally a metamorphic rock. By the definition of the word metamorphic rocks are rocks that have been formed from other rocks (sedimentary or igneous) either by formation of new minerals because of temperature and pressure changes or by changing the texture of the rock by large stresses shearing the rock.
Gneiss would be one such rock. High-grade metamorphic rock describes the type of rock based on the formational parameters of the question.
