Fabric is structures that u can see in rock. Folicated- structure/ fabric is characterized by parallel / sub parallel lines. Sedimentary rocks: only found on surface of earth. Soil, biological processes, organic processes, movement of classtic material aka bits of pieces of fragments of minerals and rocks moved around by water, wind, gravity.
