Question

all rocks are identified on the basis of their texture and composition. what are the two types of textures for metamorphic rocks? coarse and clastic foliated or nonfoliated clastic or crystalline

Explanation:

To determine the two types of textures for metamorphic rocks, we recall geological knowledge: Metamorphic rocks have textures classified as foliated (with aligned mineral grains, e.g., gneiss) and non - foliated (mineral grains not aligned, e.g., marble). The option "coarse and clastic" is incorrect (clastic is for sedimentary, coarse is a general grain size term). "Clastic or crystalline" is also incorrect (clastic for sedimentary, crystalline is a general term for mineral structure). So the correct option is the one with "foliated or nonfoliated".

Answer:

B. foliated or nonfoliated (assuming the second option is labeled B; if the original had no labels, based on the options, the correct one is "foliated or nonfoliated")
