Relative dating to determine the age of rocks and fossils. Geologists have established a set of principles that can be applied to sedimentary and volcanic rocks that are exposed at the Earth's surface to determine the relative ages of geological events preserved in the rock record.
In contrast, fibers from natural sources are provided by nature in ready-made form. Natural fibers include the protein fibers such as wool and silk, the cellulose fibers such as cotton and linen, and the mineral fiber asbestos. Plant fibers can be further on classified as:1  Fibre occurring on the seed (raw cotton, java cotton). 2  Phloem fiber (flax, ramie, hemp, jute).n contrast, fibers from natural sources are provided by nature in ready-made form.

What many do not realize, however, is that cellulose is actually wood pulp. Unable to be digested by humans due to the lack of necessary enzymes needed to break the ingredient down, cellulose has been deemed âsafe for consumptionâ by the FDA.Cellulose is virgin wood pulp that has been processed and manufactured for different functions, such as its prime use throughout the food supply.Cellulose can be found in products under ingredient listings such as cellulose gum, powdered cellulose, microcrystalline cellulose, and more.hat many do not realize, however, is that cellulose is actually wood pulp.
