Nel 2013 è stato riconosciuto come Patrimonio dell'Umanità dall' UNESCO in quanto "Uno dei vulcani più emblematici e attivi del mondo". L'Etna, infatti, presenta quasi ogni anno fenomeni eruttivi significativi.]]> 2021-02-24 12:57:58 UTC https://padlet.com/profssaborga/Bookmarks/wish/1236023909 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1236024271 Quando le acque erodono un terreno non omogeneo costituito da ciottoli immersi in altri materiali si formano le piramidi di terra. I ciottoli di dimensione maggiori proteggono il terreno sottostante dall'erosione delle acque che si esercita intorno. Si forma così una struttura a forma di colonna o piramide. La sua esistenza è però precaria: dura infatti fino a quando il masso di copertura non crolla. Suggestivi gruppi di piramidi si possono osservare a Ritten (Bolzano)]]> 2021-02-24 12:58:05 UTC https://padlet.com/profssaborga/Bookmarks/wish/1236024271 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1236024979 Il fenomeno del carsismo si verifica dove vi è una massiccia presenza di rocce calcaree ricche di carbonato di calcio. L'acqua piovana corrode le rocce e penetra in profondità, fino a fermarsi quando incontra la roccia impermeabile. Qui conitnua comunque a scavare nel calcare formando le grotte carsiche, dove si trovano le caratteristiche stalattiti (che pendono verso il basso) e le stalagmiti (che si ergono verso l'alto). In Italia sono famose le Grotte di Frasassi (Marche)]]> 2021-02-24 12:58:18 UTC https://padlet.com/profssaborga/Bookmarks/wish/1236024979 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1236025567 Le cascate di Acquafraggia in val Bregaglia (Lombardia): dall'ampia conca formata da un antico circo glaciale l'acqua precipita a valle per 1800 metri con vari balzi, da qui il nome di origine latina "acqua fracta", cioè acqua spezzata.]]> 2021-02-24 12:58:29 UTC https://padlet.com/profssaborga/Bookmarks/wish/1236025567 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1250676200 2021-02-28 19:35:26 UTC https://padlet.com/profssaborga/Bookmarks/wish/1250676200 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1250677051 2021-02-28 19:35:55 UTC https://padlet.com/profssaborga/Bookmarks/wish/1250677051 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1250677902 2021-02-28 19:36:24 UTC https://padlet.com/profssaborga/Bookmarks/wish/1250677902 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1250861714 2021-02-28 21:23:04 UTC https://padlet.com/profssaborga/Bookmarks/wish/1250861714 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1250872088 2021-02-28 21:29:45 UTC https://padlet.com/profssaborga/Bookmarks/wish/1250872088 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1250879875 2021-02-28 21:34:42 UTC https://padlet.com/profssaborga/Bookmarks/wish/1250879875 profssaBorga https://padlet.com/profssaborga/Bookmarks/wish/1250882025 2021-02-28 21:36:12 UTC https://padlet.com/profssaborga/Bookmarks/wish/1250882025
