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.
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 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 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 is pillow lava evidence of sea floor spreading?
Evidence shows that molten material erupts through this valley. The material then hardens to form the rock of the ocean floor.-Answered by Nadezda Dimsoski
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.
What occurs at divergent boundaries and creates new seafloor?
At divergent plate boundaries the spreading of the tectonic plates results in the reduced pressure of the underlying magma. As the spreading continues, lava fills in the area of spreading and cools, becoming the newest addition to the seafloor. This process occurs at a steady rate ranging from a few centimeters to several centimeters of new sea floor each year. However, at a different location opposite the newly formed seafloor are convergent plate boundaries where land and seafloor is destroyed to make room for new seafloor.

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 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.
Which of these is the best evidence of seafloor spreading-ocean ridges-mid-oceanic mountains-volcanic islands-ocean trenches?
Ocean ridges is somewhat vague. Mid-ocean mountains are more precisely called mid-ocean ridges, so it seems like someone is trying to trip you up. The best evidence of seafloor spreading among the choices would be mid-ocean mountains. They are the buoyant, hot, new crust that is formed at the divergent plates of the world's oceans.
