Question

Which of the rocks below correctly completes the following sequence of increasingly metamorphosed rocks: slate → phyllite → _________ → gneiss → migmatite?

1) schist
2) shale
3) mylonite
4) hornfels
5) eclogite

Answer 1

The correct rock that completes the sequence is schist.

Step-by-step explanation:

The correct rock that completes the sequence of increasingly metamorphosed rocks is schist.

The sequence of increasingly metamorphosed rocks is: slate → phyllite → schist → gneiss → migmatite.

Schist is a foliated metamorphic rock that forms as a result of high-grade metamorphism. It is characterized by the presence of visible mineral grains, such as mica and amphibole, and has a medium to coarse-grained texture.
