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 (0)Reader Challenges (0)All Natural PhenomenaFilter Results356 entriesBiomeAllAbyssal Zone (1)Alpine (1)Bathyal Zone (1)Boreal Forest (1)Chaparral (2)Cold Seep (1)Desert (8)Estuary (1)Fen (1)Freshwater (1)Freshwater Marsh (1)Grassland (5)Hadal Zone (1)Hydrothermal Vent (1)Ice Sheet (1)Lake (1)Marine (3)Neritic Zone (1)Paramo (1)Polar Desert (1)Puna (1)Riparian Zone (1)Savanna (2)Seagrass Meadow (2)Steppe (1)Temperate Forest (2)Temperate Rainforest (1)Tropical and Subtropical Coniferous Forest (1)Tropical Dry Forest (1)Tropical Rainforest (1)Tundra (4)Vernal Pool (1)Wetlands (2)Xeric Shrubland (1)PeriodicityAllAbout 13 or 14 times per century (1)Annual breeding seasons in many amphibians (1)Annual, May through July, not every year (1)Autumn or early winter, 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 56Solar EclipseAstronomical PhenomenaSolar FlareAstronomical PhenomenaSort solAnimal Behavior and AdaptationSpeciationEvolutionary ProcessesSt. Elmo's FireAtmospheric OpticsStarling MurmurationBiological and Seasonal PhenomenaSTEVEGeological and Atmospheric PhenomenaStorage effectEcological ProcessesStorm SurgeOcean and Marine PhenomenaStottingAnimal Behavior and AdaptationSubspeciesEvolutionary ProcessesSuccessionEcological ProcessesSulfur CycleBiogeochemical CyclesSun DogAtmospheric OpticsSun PillarAtmospheric OpticsSunbreakClimate and Weather PatternsSuperbloomBiological and Seasonal PhenomenaSupermoonAstronomical PhenomenaSuperorganismEcological ProcessesSylvanshineGeological and Atmospheric PhenomenaSymbiogenesisEvolutionary ProcessesSymbiosisEvolutionary ProcessesSympatric speciationEvolutionary ProcessesSynurbizationAnimal Behavior and AdaptationThanatosisAnimal Behavior and AdaptationThermoregulationAnimal Behavior and AdaptationThundersnowSevere Weather and StormsTidal BoreOcean and Marine PhenomenaTidesOcean and Marine PhenomenaTornadoSevere Weather and StormsTorporAnimal Behavior and AdaptationTrade WindsClimate and Weather PatternsTransit of MercuryAstronomical PhenomenaTransit of VenusAstronomical PhenomenaTrophic CascadeEcological ProcessesTropical CycloneSevere Weather and StormsTsunamiGeological EventsUpper-atmospheric lightningGeological and Atmospheric PhenomenaUpwellingOcean and Marine PhenomenaVernalizationAnimal Behavior and AdaptationVirgaCryospheric and Ice PhenomenaVolcanic EruptionGeological EventsVolcanic LightningAtmospheric OpticsWaggle danceAnimal Behavior and AdaptationWall CloudAtmospheric OpticsWater CycleBiogeochemical CyclesWaterspoutSevere Weather and StormsWeatheringGeological and Atmospheric PhenomenaWhale FallEcological ProcessesWhirlpoolOcean and Marine PhenomenaWhistler (radio)Geological and Atmospheric PhenomenaWhiteoutSevere Weather and StormsWildebeest MigrationAnimal Behavior and AdaptationWildfireGeological and Atmospheric PhenomenaWoody plant encroachmentEcological ProcessesZodiacal LightAstronomical Phenomena← Previous1234SourcesNational Oceanic and Atmospheric Administrationtier 1National Oceanic and Atmospheric AdministrationContains: AuroraContains: MonsoonContains: TidesContains: Ocean CurrentsView the SourceEncyclopaedia Britannicatier 1Encyclopaedia Britannica, Inc.Contains: WildfireView the SourceWhat Is Ecological Succession?
