Nom<\/strong><\/p>\n

Catal\u00e0: Bomba volc\u00e0nica<\/strong>
\nCastell\u00e0: Bomba volc\u00e1nica
\nAngl\u00e8s: Volcanic pump
\nFranc\u00e8s: Pompe volcanique<\/p>\n

\"Resultado\"Resultado<\/p>\n

Quin tipus de roca i\/o mineral \u00e9s?<\/strong><\/p>\n

\u00c9s una massa de roca fosa (piroclasts: fragments s\u00f2lids que el volc\u00e0 projecta enlaire. Dep\u00e8n de com
\n\u00e9s la mida s\u2019anomena de diferents noms.). \u00c9s una roca que prove de l\u2019interior de la Terra: \u00e9s una
\nroca tipus magm\u00e0tica.<\/p>\n

Formaci\u00f3 de la roca i\/o mineral<\/strong><\/p>\n

Es forma quan un volc\u00e0 expulsa fragments viscosos de lava durant una erupci\u00f3.<\/p>\n

Composici\u00f3 qu\u00edmica<\/strong><\/p>\n

La composici\u00f3 qu\u00edmica \u00e9s la mateixa que la del magma: oxigen (O), silici (Si), alumini (Al),
\nferro (Fe), calci (Ca), sodi (Na), potassi (K) i magnesi (Mg).<\/p>\n

Breu descripci\u00f3 (color, textura…)<\/strong><\/p>\n

El color varia d\u2019un gris a un negre; t\u00e9 una textura rugosa perqu\u00e8 al ser expulsat, adquireix aquesta
\ntextura. Els fragments poden mesurar des d\u2019uns quants cent\u00edmetres a uns quants metres.<\/p>\n

Usos i\/o aplicacions<\/strong><\/p>\n

S\u2019utilitza com a element de decoraci\u00f3, petits fragments de bombes volc\u00e0niques s\u2019utilitza per a les plantes.<\/p>\n

Lloc d’origen (Jaciments m\u00e9s importants)<\/strong><\/p>\n

Bomba volc\u00e0nica a Tenerife, Espanya (1.); Renania-Palatinado, Alemanya (2.).
