Home›Natural Phenomena›All Natural PhenomenaBrowse ByAll Natural PhenomenaReference and ClassificationDevelopingNatural phenomena are the events and processes nature produces, rather than the living things or places that host them: migrations, blooms, and geological or weather events with a natural history dimension. This category excludes phenomena that belong to Earth or Space as a discipline unless nature carries a distinct biological or ecological facet those atlases do not.All Natural PhenomenaSourcesComments

usually seen in the early morning (1)Forms on cold, clear nights (1)Life cycle of some 30 to 60 years per circle (1)Occur in all the world's oceans many times each day (1)Occurs when conditions turn cold (1)Perigean spring tides occur three or four times a year (1)Rare, because moonlight is far dimmer than sunlight (1)Seasonal, stronger in winter (1)Varies with the 11-year solar cycle (1)ScaleAllAtmosphere is 21 percent oxygen, roughly 3.4x10^19 mol of O2 (1)Circles more than 15 metres in diameter observed (1)Diameters from 30 cm to 3 m, thickness up to 10 cm (1)From a few centimetres to over 5 metres long (1)Landscape, total species diversity (1)Layer depth from about 20 to 30 m up to 300 m (1)Local scale, mean species diversity within a site (1)Perhaps 40 percent of described species are parasitic (1)Short-lived, seldom lasting longer than 10 minutes (1)Widespread in insects, less so in vertebrates (1)Show ResultsBrowseCompareSelect all 100Earthquake
