Answer:
Grade of metamorphism
Explanation:
Gneiss forms at a higher grade of metamophic slate. Slate forms at low metamorphic conditions just about a few temperature and pressure.
From the prolith materials exposed to metamorphic conditions, transformations begins as metamorphic changes begins to take place. First, a sediment is transformed into slate, from slate to phyllite, from phyllite to schist, schist to gneiss, gneiss to migmatite and migmatite goes back to melt. These transformation of sediments is controlled by the nature of the prolith materials and the prevailing metamorphic conditions.
Wrap your specimen in the original wrapping and give it your instruct to dispose of
The fern should be found on the west side of the mountain ranges at higher elevations because the prevailing winds are from the west off the Pacific Ocean so bring moisture in the clouds and as the clouds rise up over the westernmost mountains they cool off and precipitate so in the warm seasons rain would be concentrated in this area and higher up would be cooler.
