How does pillow basalt form?
Pillow basalt forms when basaltic lava erupts underwater and cools rapidly, creating pillow-shaped structures. Water cools the lava quickly, causing it to solidify into distinctive pillow-like shapes as it is extruded.
What is pillow lava?
Pillow lava is basaltic lava that forms rounded pillow like lumps. It forms when a volcano erupts fairly deep underwater. Lava erupts bu quickly crusts over, creating a bulbous formation. The crust then breaks and more lava spills out, continuing the process.See the link below for a video of pillow lava.
Pillow lava is the result of what type of eruption?
Pillow lava is the result of underwater volcanic eruptions. When hot magma is extruded onto the ocean floor, it cools rapidly and forms pillow-shaped structures due to the rapid cooling process in the water.
Lava that forms underwater as rounded lumps?
This type of lava is known as pillow lava. When molten lava is erupted underwater, it quickly cools and solidifies into pillow-shaped structures due to the rapid cooling effect of the surrounding water. Over time, multiple layers of pillow lava can accumulate to form underwater volcanic structures.
How did pillow lava get its name?
Pillow lava got its name because of its distinctive pillow-like shapes that form when lava flows underwater and cools rapidly. As the outer layer of lava cools and solidifies quickly upon contact with water, it forms a rounded mound resembling a pillow. This unique shape is characteristic of lava flows in underwater volcanic environments.

How hot is pillow lava?
pillow lava is 2500 degrees

Does pillow lava have high silica?
No. Pillow lava is basaltic, so it has a low silica content.

Does Krakatoa make pillow lava?
No. Pillow lava is basaltic, low-viscosity lava. Krakatoa is a stratovolcano with a style of ereuption more characteristic of high-viscosity andesitic lava.

Where would you expect to find pillow lava in the modern world?
in a volcano Pillow lava forms only when lava emerges from a place that is submerged under water.
How are Pillow Lava and Pahoehoe lava the same?
Both pillow lava and pahoehoe lava are types of basaltic lava that form during submarine volcanic eruptions. They both have smooth, ropy surfaces, caused by the flow of lava, and are relatively low in viscosity.
How does rising magma and flowing lava create underwater pillow lava?
Because the magma is erupted into the cold water, the outside of the flow quickly cools and solidifies into a hard shell which causes the backside flow to seek a new, less resistant pathway. When the flow is pinched off before re-routing, a bulbous pillow shaped, rapidly cooling blob is formed. Most of the ocean floor laying under layers of sediment and sedimentary rock, is formed from masses of pillow lavas (basalt).
How is pahoehoe lava different from pillow lava how are they similar?
Pahoehoe lava has a smooth, undulating surface texture due to its high temperature and low viscosity, while pillow lava has a bulbous, rounded shape formed when it cools underwater. They are both types of basaltic lava flows found in volcanic environments, with pahoehoe typically found on land and pillow lava commonly found under the sea.
