Pareidolia ( / ˌpærɪˈdoʊliə, ˌpɛər -/; [ 1] also US: / ˌpɛəraɪ -/) [ 2] is the tendency for perception to impose a meaningful interpretation on a nebulous stimulus, usually visual, so that one detects an object, pattern, or meaning where there is none. Pareidolia is a type of apophenia . Common examples include perceived images of ...
Patterns in nature are visible regularities of form found in the natural world. These patterns recur in different contexts and can sometimes be modelled mathematically. Natural patterns include symmetries, trees, spirals, meanders, waves, foams, tessellations, cracks and stripes. [ 1] Early Greek philosophers studied pattern, with Plato ...
In geomorphology, drainage systems, also known as river systems, are the patterns formed by the streams, rivers, and lakes in a particular drainage basin. They are governed by the topography of land, whether a particular region is dominated by hard or soft rocks, and the gradient of the land. Geomorphologists and hydrologists often view streams ...
Geomorphology (from Ancient Greek: γῆ, gê, 'earth'; μορφή, morphḗ, 'form'; and λόγος, lógos, 'study') [ 2] is the scientific study of the origin and evolution of topographic and bathymetric features generated by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand ...
Location of Nazca lines in Peru. The Nazca lines ( / ˈnɑːzkə /, /- kɑː / [ 1]) are a group of geoglyphs made in the soil of the Nazca Desert in southern Peru. [ 2] They were created between 500 BC and 500 AD by people making depressions or shallow incisions in the desert floor, removing pebbles and leaving different-colored dirt exposed. [ 3]
Biomorphism models artistic design elements on naturally occurring patterns or shapes reminiscent of nature and living organisms. Taken to its extreme it attempts to force naturally occurring shapes onto functional devices. [1] In his search for architectural reform the French architecte Viollet le Duc is the first to express this idea clearly ...
A natural landscape is the original landscape that exists before it is acted upon by human culture. [ note 1] The natural landscape and the cultural landscape are separate parts of the landscape. [ note 2] However, in the 21st century, landscapes that are totally untouched by human activity no longer exist, [ 3] so that reference is sometimes ...
Geology of Norway. Geological map of Fennoscandia. The geology of Norway encompasses the history of Earth that can be interpreted by rock types found in Norway, and the associated sedimentological history of soils and rock types. The Norwegian mountains were formed around 400 million years ago (Ma) during the Caledonian orogeny .
