Answer:

Foliation is the repetitive layering of rocks due to intense directed pressure. Foliated rocks are characterized by linear streaks that vary in width. Non-foliated metamorphic rocks do not have these streaks.

Explanation:

It occurs among metamorphic rocks that are subjected to intense directed pressure which causes the minerals within the rock to flatten or realign perpendicularly from the area of greatest pressure.
