Natural phenomenon
A natural phenomenon is an observable event which is not man-made. Examples include: sunrise, weather, fog, thunder, tornadoes; biological processes, decomposition, germination; physical processes, wave propagation, erosion; tidal flow, and natural disasters such as electromagnetic pulses, volcanic eruptions, and earthquakes.[1][2]
Exposure to forces of nature[vague] resulted in about 214,000 deaths in 2010, up from 31,000 in 1990.[3]
Types
Types of natural phenomena include, but are not limited to, the following.
Biological
- Decomposition – by which organic substances are broken down into a much simpler form of matter
- Metabolism
- Catabolism
- Anabolism
- Fermentation – converts sugar to acids, gases and/or alcohol.
- Growth
- Population growth
- Overpopulation growth beyond carrying capacity
Chemical
Geological
Geological processes include erosion, sedimentation, and volcanic activities such as geysers and earthquakes.
Meteorological
Violent meteorological phenomena are called storms. Regular, cyclical phenomena include seasons and atmospheric circulation. Climate change is often semi-regular.
