Meaning of Period
What is Period:
A period of time is called a determined period of time in which an action, a phenomenon or a succession of concatenated events unfolds.
As a rule, it is usually used to refer to phenomena that are repeated in a cyclical way, or events that are related to each other.
The term can also be used to account for the time necessary for a thing, person or situation to reach certain conditions or maturity.
For example, the expression "ripening period" is used when talking about fruits and vegetables. Similarly, we speak of an "adaptation period" when we speak of a person who begins a new stage and must adjust to their conditions.
The term is quite broad and can be applied to any area such as history, biology, geology, etc. as it can be seen.
Period in history
In the discipline of history, "ages" are made up of periods. For example, the Ancient Age is made up of the Archaic, Classical, and Hellenistic periods. This practice of grouping sequences of historical events at specified times is called periodization.
See also Time.
Period in science
In science, a period refers to repetitive cycles. In medicine, physiology and biology, for example, one can speak of the "incubation period" of a bacterium or virus, the woman's "menstrual period" and the "gestation period" of a pregnancy, among many others.
In chemistry, the term period is related to the periodic table of chemical elements. The periodic table is made up of periods, which correspond to the horizontal rows of it. They present the physical and chemical properties of the different elements.
In physics, one can speak of the period of oscillation to refer to the interval time of a wave between one point and another.
In disciplines that study the formation of the earth, such as geology, a period refers to a specific period of time in which similar phenomena are grouped that consolidated certain environmental and biological conditions. For example, we speak of the Jurassic and Triassic period, which in turn make up "eras."
