What is clastic, chemical and organic?
Type of metamorphic rock with visible layers
What is foliated?
Igneous rocks that are high in silica/ light colored
What is felsic?
Organic sedimentary rock is made out of this
What is the remains of living things?
Type of metamorphic rock with no layers/bands
What is unfoliated?
The texture of igneous rock that contains both small and large crystals
What is porphyritic?

What is cementation?
True or false: This is the least abundant of the three rock categories
What is true?
The four types of texture of igneous rocks
What are coarse-grained, fine-grained, no crystals and porphyritic?
Sedimentary rock that is formed from water forming minerals that cement that fragments together
