Which phenomenon explains the rapid cooling of pillow lava?

💡 Explanation

Hyaloclastite forms along subaqueous lava flows via thermal fracturing; the outer lava surface rapidly cools and shatters via quenching because the high water-lava temperature differential forms brittle fragments; therefore hyaloclastite, rather than the cooling/textural styles above water is promoted.

• Along coastlines, which outcome occurs when persistent offshore winds drive surface water away from the shore?
• Which localized outcome accelerates when groundwater extraction weakens coastal sediment structure?
• Which landscape results when prolonged deflation lowers land?
• Which outcome results when differential weathering weakens coastal rock formations?
• Which outcome reduces sand supply offshore when coastal engineering disrupts sediment transport?
• Which risk increases when a fjord's stratification weakens?
