Natural phenomenon

From Wikipedia, the free encyclopedia

This parabola-shaped lava flow illustrates Galileo's law of falling bodies as well as blackbody radiation -- you can tell the temperature from the color of the blackbody.

A natural phenomenon is a non-artificial event in the physical sense, and therefore not produced by humans, although it may affect humans (e.g. bacteria, ageing, natural disasters). Common examples of natural phenomena include volcanic eruptions, weather, and decay.

Aurora is one of a natural phenomenon

Most natural phenomenons are harmless such as rain. Some natural phenomenons such as Volcanic Eruption, Tsunami, Tornadoes are considered dangerous and might lead to death.
