Vulcani sono strutture geologiche che si originano in seguito alla risalita di magma dalla crosta terrestre e dal mantello e, quello che solitamente vediamo, è solo una parte di tutto il vulcano. I vulcani sono strutture geologiche complesse, delle fratture naturali che si formano all'interno della crosta terrestre dalla risalita in superficie di magma e di altri prodotti dell'attività eruttiva che può avvenire con manifestazioni di vario tipo. Questo materiale, dopo l’eruzione, va a formare il cosiddetto “cono vulcanico”, che è la parte della struttura di un vulcano che osserviamo normalmente. Solitamente i vulcani si formano lungo i margini di placca e hanno forme diverse a seconda del meccanismo che li ha generati. CHE COS’E’ UN VULCANOIl “vulcano” (dal latino Vulcanus «Vulcano», nome del dio del fuoco e di un’isola dell'arcipelago delle Eolie) è una discontinuità della crosta terrestre, solitamente composto da una parte invisibile che si trova sotto la superficie, rappresentata dalla camera magmatica e dai condotti magmatici nella crosta, e da una parte visibile ai nostri occhi, cioè il rilievo vulcanico, il cosiddetto «cono» o edificio, cioè quella struttura che si trova al di fuori della crosta terrestre. In realtà questa è solamente l’espressione esterna di una struttura geologica complessa che in buona parte si trova in profondità: il cono vulcanico è solo la punta dell’iceberg! La struttura di un vulcano, infatti, è costituita da tre elementi:

This is your story’s title

This story includes several of the pieces you might use in your own story–like paragraphs, buttons, separators, and more. To get started, select a section of the styling panel and make some adjustments. As you adjust different elements, you’ll see this story adjust to demonstrate how they look. Try changing the paragraph font, and see what happens to this text.

This is the title for the story credits. It uses the title font.

This is where the credit description goes; it uses the paragraph font.

Next, try adjusting the button style and see how your selection affects the button below. You’ll also notice that it uses the paragraph font for its text.

You can style your paragraph text to use bold, italics, and bold italics, so you can emphasize important text accordingly. These come pre-packaged with the fonts you’ve chosen, so there’s nothing extra you need to configure.

Quotes use the theme’s title font, but you can also choose one of several different styling options.

Your theme’s accent color is used in both quotes (see above) and separators (below). If you add an express map to your story, your drawn features will use the accent color too.

You have a few different options for separator styles; toggle between them and see how the separator above changes.
