Pillow lava is a type of basaltic lava that forms underwater, mostly in the ocean. It’s name is given from its characteristic pillow-like shapes that the it takes on as it rapidly cools and solidifies in the cold water. This process is known as “pillowing.”
Pillow lava forms when molten lava erupts underwater, cooling rapidly into rounded, pillow-like shapes. This process has been occurring for millions of years, primarily at mid-ocean ridges, underwater volcanoes, and rift zones. Scientists first studied pillow lava in oceanic regions, helping to understand seafloor spreading and Earth’s geological history.
Pillow lava is rounded, pillow-like structures due to rapid cooling. It is Smooth with glassy outer shell with a crystalline interior. It has a dark gray to black, often with greenish tints due to mineral content.
Pillow lava occurs when lava erupts underwater, cools instantly, and solidifies in layers.
It is found in oceanic crust, volcanic islands, and ancient marine rock formations on land.
It helps scientists understand underwater volcanic activity and Earth’s crust formation.
Some pillow lava rocks are used in construction and road building.
It is used in landscaping and aquarium decorations.
