Definition of Natural Sciences

The word Science refers to the grouping of knowledge on a certain topic that is achieved by reasoning and experimentation applied in a methodical and systematic way, supported by the scientific method. In accordance with the object of the study, it receives various types of classification.

In the case of natural Sciences, It is the branch of science that is responsible for the study of nature in order to decipher the theories and laws by which the natural world works.

In order to better organize this knowledge, the natural sciences are divided into four major branches, which are: Biology, Chemistry, Physics and Geology, each of them has divisions that cover more aspects specific.

biology

It is the science that studies living beings, it is formed in turn by other sciences that allow to expand that study, as is the case of the Biochemistry which is responsible for the study of the molecular mechanisms of life and metabolism, the

Histology that passes to the microscopic study of tissues and cells, the Physiology that teaches us how living beings work and the Genetics It deals with aspects related to the laws that govern the inheritance of information between different generations. A great classification of biology is given based on the kingdom to which living beings belong, as is the case of the Zoology that studies the beings of the animal kingdom, the Botany to the vegetal kingdom, the Microbiology studies microscopic beings, the Ecology that studies the interrelation with living beings and their environment.

Chemistry

It is a basic science that is interrelated with many other sciences and its object of study is matter, chemistry teaches us what matter is, what its structure and composition are, its types, how it behaves and what are its properties. For this, chemistry has two main branches such as Organic chemistry which is responsible for the study of the compounds that are formed by carbon and the Inorganic chemistry study the molecules that do not contain it. Chemistry relies on the other disciplines to be able to specify this study, deriving sciences such as Biochemistry, Physical chemistry, Petrochemistry and the Astrochemistry, among other.

Physical

Once chemistry explains what matter is and how it is formed, physics teaches us how it interacts with its environment, especially the relationship between matter, space, time and Energy, in order to understand the phenomena that occur in nature and to be able to describe and predict them through identification of the laws that govern them, for this is closely related to mathematics, which is the language of physics. Physics comprises several branches that include Mechanics or science of forces and motion, Thermodynamics which deals with the study of the exchange between heat and energy as well as its Balance between systems, Electromagnetism explains phenomena such as electricity and the magnetism and the interrelation with each other, Astrophysics study the laws that govern the universe, Relativity which describes the relationships between gravity and spacetime as well as the physical phenomena that occur at speeds close to the velocity of the light, Quantum physics which explains the interrelationship between the particles at the atomic level.

geology

It is the science that is responsible for the study of the earth from its origin to the present, for this it is based on the study of the aspects related to the composition and the different processes that occur in rocks, the earth's crust, the atmosphere and the interior of the land. Geology relies on other sciences such as Physics, Chemistry and Biology, thus deriving its main branches, among which it is found Geophysics, Geochemistry, Geobotany, Zoogeology and the Paleontology.
