The Natural materials Are the matter that is harnessed by humans and which come from natural elements, such as plants, animals or the earth's crust.
Natural materials can be biotics, which are those that come from living things. For example, wood, cotton, pulp, honey, leather and wool are natural materials because they come from plants and animals.
Inorganic materials are also found. Among the inorganic materials, rocks, minerals and metals stand out.
Natural materials are in the pure state in nature. For example, silver can be extracted from different points in the Earth crust .
Some of the materials are formed without the intervention of humans (such as Petroleum , Coal and diamonds) while others require human action (such as leather, natural fabrics and wood).
It should be noted that even after being modified and processed, this type of materials will continue to be natural. For example, purified silver remains natural.
Examples of natural materials
Leather is a material that is obtained from the skins of some animals.
To produce leather, the animals must be skinned and subsequently skinned to achieve the desired finish.
Most commercial milk is obtained from livestock, mainly cattle.
3- Natural Fertilizers
Natural fertilizers are extracted from biological material in the process of decomposition.
In general, animal excrement and vegetable waste are used as fertilizers.
Guano is a type of animal manure that is produced by the accumulation of excrements of seabirds. It is found in large quantities in the islands.
Feathers are used as ornamental elements in the clothing industry, such as pillow fillings and writing materials.
This is a fabric that is formed with the sheep's coat.
Cotton is a plant that produces a fiber that is used to make fabrics. The fabric produced is also called cotton.
It is known as silk the set of filaments produced by some caterpillars.
From these filaments, a fabric is created that receives the same name.
Wood is one of the most common natural materials, which is extracted from trees.
Wood that is extracted from the plant that receives the same name.
It is used in the production of fishing rods, furniture, among others.
This material is obtained from the internal tissues of the stem of some trees.
Most of the cork that is marketed comes from the cork oak tree.
This is a molasses that is created with the sap of the maple tree.
This is a material in the form of powder, which is obtained from other materials (such as limestone).
It is the most abundant metal on planet Earth.
It is the second most abundant metal on the planet. Its versatility has allowed it to be used in various areas: in construction, in goldsmithing, in the armory, among others.
Copper is a brownish-brown metal, sometimes reddish. This is a very good conductor of electricity. For this reason, it is widely used in the electrical wiring system.
Granite is an eruptive, intrusive rock. It gets its name because its appearance is grainy. Because of its attractiveness, it is used in buildings as an ornamental element.
It is a type of white sedimentary rock, used in the production of compact powders used for writing.
Gold is a precious metal, an excellent conductor of electricity. It is mainly used in jewelry.
It is a metallic element of white color. It is used in various areas, including jewelry.
Metallic element, blue. It is highly harmful to health.
Platinum is a white metal used as a catalyst.
Clay is a sedimentary rock. When mixed with water, it forms a malleable paste which acquires hardness when cooked.
The pearls are the product of some mollusks, which are formed from the secretions they generate to eject foreign elements.
Petroleum is a hydrocarbon that is formed by the decomposition of large quantities of organic matter in the absence of oxygen. It is one of the most important fuels in the world.
Coal is a very useful material since it constitutes a fuel.
This is formed from charring plant remains that have been preserved as fossils.
Graphite is a material derived from carbon. It is a good conductor of electricity so it is used in electrical circuits and electrodes. In the same way, with the graphite are produced pencils.
28- Pumice stone
This is an effusive rock, characterized by its pores. It is used in construction.
Precious, transparent stone. It is formed by the crystallization of carbon, which occurs at high temperatures.
The ruby is a reddish gemstone. It is used in jewelry.
Quartz is a precious stone. Its color varies according to the additional components it presents. In this sense, there are pink, white, transparent quartz, among others.
It is a gemstone of green color and rhomboid form.
The lapis lazuli is a precious stone of hard consistency and of blue color. It is usually in the form of cubes.
The limestone is a sedimentary rock and is usually white. It is used to produce building materials.
