Suppose this rock were exposed to high temperature and pressure. what would most likely happen to it?plss guys help

the rock won't melt rather under very temperatures the living organisms die and if the temperature and pressure increases for several years (nearly a million )then there are chances for the rock to turn to a fossil or as a fossil fuel  

Explanation:

i am a little confused myself with what goes with the letters and what goes with the numbers but ill do my best to you

the cordillera states and grand canyon are along the southwest u.s. and northern mexican pacific.

the great plains and southwest desert are also the prairie and home to many earthquakes too .

the coastal plains have poor soil and many factories started in the south.

is this what u needed? if not i can see what i can do
