Phenomena can be defined as “observable events that occur in a natural or designed system.” They are everywhere around us, but some are easier to notice than others. Common examples of natural phenomena include lightning, earthquakes, tsunamis, volcanic eruptions, tornadoes, and similar.
In natural sciences, a phenomenon is an observable happening or event. Often, this term is used without considering the causes of a particular event. Example of a physical phenomenon is an observable phenomenon of the lunar orbit or the phenomenon of oscillations of a pendulum.
Types of natural phenomena include: Weather, fog, thunder, tornadoes, biological processes, decomposition, germination, physical processes, wave propagation, erosion, tidal flow, moonbow, blood moon and natural disasters such as electromagnetic pulses, volcanic eruptions, earthquakes, midnight sun and polar night.
The word phenomenon comes from Greek, and its plural form is phenomena, as in: These phenomena are not fully understood. It is a mistake to treat phenomena as if it were a singular form, as in: This is a strange phenomena.
A natural phenomenon is not an engineered event manufactured by humans, although it may affect them. Common examples of natural phenomena include sunrise, the weather, decomposition, free fall and erosion. Most natural phenomena, such as fog, are relatively harmless so far as humans are concerned.
Scientists distinguish between phenomena, which are their systematic observations, and theories, which are their explanations or interpretations of phenomena.
Science requires that scientific explanations of phenomena be based on events or mechanisms that can be observed in the natural world. They propose hypotheses that explain the evolution of those characteristics through naturally occurring mechanisms. Then they gather additional information to test their hypotheses.
They organize phenomena, allow people to predict what will happen in new situations, and help generate new research. Researchers generally consider multiple theories for any set of phenomena. Different theories of the same set of phenomena can be complementary or competing.
Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus (purulent material), causing cough with phlegm or pus, fever, chills, and difficulty breathing. A variety of organisms, including bacteria, viruses and fungi, can cause pneumonia.
Scientists test hypotheses by making predictions: if hypothesis Xstart text, X, end text is right, then Ystart text, Y, end text should be true. Then, they do experiments or make observations to see if the predictions are correct. If they are, the hypothesis is supported.
