The solar photosphere is a thin layer of roughly 300 km wide. Its temperature decreases uniformly with height, from about 6,600 K (pressure 0.868 millibars) at its bottom, to about 4,400 K (pressure 125 mb), where it merges with the chromosphere. The photosphere has a 'rice-grain' appearance, called granulation, caused by rising (hot) and falling (cool) material in the convective cells just below the photosphere. Other main features of the photosphere are sunspots, faculae, and supergranulation.", "narrower" : [{"_about" : "http://astrothesaurus.org/uat/1875", "broader" : ["http://astrothesaurus.org/uat/1518"]} ], "prefLabel" : {"_value" : "Solar photosphere", "_lang" : "en"} , "related" : [{"_about" : "http://astrothesaurus.org/uat/1237", "related" : ["http://astrothesaurus.org/uat/1518"]} ], "type" : ["http://www.w3.org/2000/01/rdf-schema#Resource", "http://www.w3.org/2004/02/skos/core#Concept"]} , "type" : ["http://purl.org/linked-data/api/vocab#ItemEndpoint", "http://purl.org/linked-data/api/vocab#Page"]} }
