Il ciclo dell&apos;acqua è un processo fondamentale che regola la distribuzione e il movimento dell&apos;acqua sulla Terra. Questo ciclo è composto da diverse fasi: evaporazione, condensazione, precipitazione e infiltrazione. L&apos;evaporazione avviene quando l&apos;acqua presente negli oceani, nei fiumi e nei laghi si riscalda a causa dell&apos;energia solare, trasformandosi in vapore acqueo. Questo vapore, una volta sollevato nell&apos;atmosfera, si raffredda e condensa formando le nuvole. Quando le particelle d&apos;acqua all&apos;interno delle nuvole diventano abbastanza pesanti, cadono sulla Terra sotto forma di precipitazione, che può manifestarsi come pioggia, neve o grandine. Il ciclo dell&apos;acqua è strettamente legato al clima. Le variazioni climatiche influenzano la quantità e il tipo di precipitazioni, nonché la temperatura, che a sua volta incide sull&apos;evaporazione. Ad esempio, in un clima caldo e secco, l&apos;evaporazione è più intensa, portando a una diminuzione delle riserve idriche. Al contrario, in un clima umido, le precipitazioni possono essere più abbondanti, contribuendo a un ciclo idrico più ricco. Inoltre, i cambiamenti climatici causati dall&apos;attività umana stanno alterando questo ciclo. L&apos;aumento delle temperature globali sta causando un incremento dell&apos;evaporazione e, di conseguenza, una maggiore intensità delle precipitazioni in alcune aree, mentre altre regioni possono sperimentare siccità più frequenti e prolungate. Questi cambiamenti possono avere ripercussioni significative sugli ecosistemi, sull&apos;agricoltura e sulle risorse idriche.

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.
