What is pillow lava?
GeologyVolcanology
Quick Answer
Pillow lava is basaltic lava that cools underwater into rounded, pillow-shaped masses. The outer skin hardens quickly while the inside keeps flowing.
The Full Story
Pillow lava forms where eruptions happen beneath the ocean or under glaciers and lakes. The rapid cooling produces rounded lobes with glassy crusts, often stacked on one another. These structures are important evidence of underwater volcanism in Earth’s past. Pillow lava is common along mid-ocean ridges, where new seafloor is created.
