Metamorphic rocks are unfoliated if their mineral grains are arranged in parallel layers or bands true or false if false why

False because Foliation forms when pressure squeezes the flat or elongate minerals within a rock so they become aligned. These rocks develop a platy or sheet-like structure that reflects the direction that pressure was applied in. Slate, schist, and gneiss (pronounced 'nice') are all foliated metamorphic rocks  Credits to :https://geomaps.wr.usgs.gov/parks/rxmin/rock3.html
