How is pillow lava evidence of sea-floor spreading?
Pillow lava forms when molten lava erupts underwater and cools rapidly, creating characteristic pillow-like structures. This type of lava is commonly found along mid-ocean ridges, which are areas where sea-floor spreading occurs. The presence of pillow lava on the ocean floor is evidence of volcanic activity associated with sea-floor spreading.

Describe the appearance of lava flows along the ocean floor?
When a volcano ejects lava from the ocean floor, the lava cools very rapidly. This causes the outside of the lava plume to solidify. Pressure builds inside this lava pillow, as it is usually described, until it breaks through a weak area in the pillow "shell" and forms a new lava pillow. The process repeats until the lava source is exhausted or the pressure wanes.
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.
How hot is pillow lava?
pillow lava is 2500 degrees
Describe pillow lava?
Pillow lava is a type of basaltic lava that forms underwater when lava erupts on the ocean floor. It cools quickly, creating pillow-shaped structures. These formations resemble stacked pillows due to the outer crust solidifying quickly while the lava inside continues to flow, resulting in rounded shapes. Pillow lava is commonly found in mid-ocean ridges and submarine volcanic environments.
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.
What happen to the magma after being pushed upward and exposed at the surface of the ocean floor?
The lava would form pillow basalts.
Does pillow lava have high silica?
No. Pillow lava is basaltic, so it has a low silica content.
What patterns indicate sea floor spreading is occurring?
Ridges, parallel to the axis of spreading, are formed in the ocean floor as hot lava moves up to fill the gap then cools when it comes in contact with sea 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.
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.
