Meaning of Cycle
What is Cycle:
A cycle is called the period of time in which a set of events, stages or phenomena develop or occur which, once completed, repeat themselves again in the same order from beginning to end.
The word cycle derives from Latin cyclus, and this in turn from the Greek kyklus which means "circle or wheel."
Cycle is a word that is widely used and can be used in different topics or areas depending on what you want to make known or relate to.
There are various cycles that, based on their characteristics, order of events, duration and repetition, are studied in various areas in order to understand the operation of many of the natural, economic, cultural, social phenomena, among others.
In nature there are various cycles that expose how life develops and a set of natural phenomena that are essential on planet Earth.
For example, the life cycle is one of the most important and studied in the field of science. In this cycle it is possible to project, for example, how in a certain period a plant is born, develops, bears fruit, dies and is reborn thanks to the seeds left behind, and thus give continuity with the cycle.
Other cycles that are also vital in nature are biogeochemical cycles, since through these a series of natural phenomena occur that are essential for life on Earth.
It can also be mentioned is the female sexual cycle, which comprises a series of hormonal changes that occur regularly every 28 days in the female reproductive system and that make menstruation or pregnancy possible.

The economic cycle refers to the different situations and oscillations through which the economy of a country or region passes, and which is characteristic of the capitalist economic model.
This cycle usually takes place in four phases. The first is the rise and economic boom, that is, a lot of productivity and commercialization.
It is followed by the decline or recession, characterized by a fall in productive activity, increased unemployment and little investment.
This is followed by the third phase, in which the crisis worsens and the economic depression is generated. Finally, recovery and reactivation appear in the last phase, at which point the economy begins to overcome, little by little, the crisis and begins its expansion.
Production cycles that start from the development, elaboration, distribution and sale of a good or service can also be included.

The cardiac cycle is a process through which electrical, mechanical and pressure changes are made, related to blood flow, contraction and relaxation in the heart chambers, as well as the opening and closing of the heart valves.
This happens quickly and its duration reflects the cycle of the heart rate or heartbeat, for every minute.
The circadian cycle refers to the order in which a set of biological variables or rhythms occur repeatedly and in a given period of time.
Circadian cycles occur in both animals and plants and can occur between every 20 to 24 hours, as is the case with light and temperature cycles.
For example, the circadian cycle of the human being is approximately 24 hours, therefore, when an alteration in this cycle occurs, a disorder is caused in the person that can even generate general discomfort.
See also Circadian cycle.
Cycle in physics
In physics, a cycle refers to the complete oscillation of a movement or wave that occurs periodically. It can also indicate the thermodynamic transformations to which a substance is subjected.

The rock cycle is part of a set of geological processes through which three main types of rocks are formed: igneous rocks, sedimentary rocks and metamorphic rocks.
The rocks are constantly undergoing changes and transforming through time, so this is a continuous cycle that does not stop on the planet.
