The word cycle derives from the Latin cyclusand this in turn from the Greek kyklus which means “circle or wheel”.

Cycle is a word that has a very widespread use and can be used in different topics or areas depending on what you want to make known or relate.

There are various cycles which, based on their characteristics, order of events, duration time and repetition, are studied in various areas in order to understand the functioning of many of the natural, economic, cultural, social phenomena, among others.

natural cycles

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, him Lifecycle It 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 given period a plant is born, develops, bears fruit, dies and is reborn thanks to the seeds left, and thus give continuity to the cycle.

Other cycles that are also vital in nature are the biogeochemical cyclessince through these occur a series of natural phenomena that are essential for life on Earth.

It can also be mentioned is the female sexual cyclewhich comprises a series of hormonal changes that occur regularly every 28 days in the female reproductive system and that make menstruation or pregnancy possible.

Economic cycle

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 ascent and the economic boom, that is, a lot of productivity and commercialization.

He is followed by decline or recession, which is characterized by a fall in productive activity, an increase in unemployment and little investment.

Next, the third phase occurs, in which the crisis worsens and the depression economic. Finally, in the last phase appears the Recovery and reactivation, when the economy gradually begins to overcome the crisis and begins to expand.

Production cycles that start from the development, production, distribution and sale of a good or service can also be included.

Cardiac cycle

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 cavities, 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 each minute.

circadian cycle

The circadian cycle refers to the order in which a set of variables or biological rhythms occur repeatedly and in a given period.

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 occurs in this cycle, 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.

See also Physics.

rock cycle

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.

Rocks are constantly undergoing changes and transforming over time, which is why this is a continuous cycle that does not stop on the planet.

See also Geology.

culture cycle

The set of activities of a cultural nature that are thematically related and that are usually developed at a given time is called a cultural cycle. For example, it is common to see literary cycles, film cycles, theater cycles, exhibition cycles, among others, in the list of activities of various cultural centers.

In these cycles, a set of conferences on artistic works that are related by their authors, periods, themes, historical events, cultural and social movements, among others, are usually exhibited and offered to the public.

For its part, in literature there are also literary cycles, which are those literary works that bring together the same events, heroes, themes and characteristics of a period.

The study cycles refer to the blocks in which the courses of study plans are divided. For example, the basic cycle (primary) and the diversified cycle (high school or high school).
