put these in order from least to most metamorphosed: gneiss, slate, schist, phyllite. sort these into foliated and non - foliated in the foliated non - foliated

Answer

Explanation:

Step1: Understand metamorphism levels

Metamorphism increases in the order slate - phyllite - schist - gneiss. Slate is the least metamorphosed as it has low - grade metamorphism and is formed from the metamorphism of shale. Phyllite has slightly higher - grade metamorphism than slate. Schist has medium - grade metamorphism with well - developed foliation. Gneiss has high - grade metamorphism.

Step2: Identify foliated and non - foliated

All of slate, phyllite, schist, and gneiss are foliated metamorphic rocks. Foliated rocks have a layered or banded appearance due to the alignment of minerals during metamorphism. There are no non - foliated rocks among these four.

Answer:

Slate → Phyllite → Schist → Gneiss Foliated: slate, phyllite, schist, gneiss Non - foliated: None
