Pillow basalt forms when lava erupts deep underwater. At a great enough depth there is enough pressure to prevent a steam explosion, so instead the water rapidly cools the surface of the lava, forming a solid crust around it. eventually the lava breaks though this crust only to have its surface cooled again, and the cycle repeats

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 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 type of lava erupts underwater and takes the form of round lumps?
Pillow lava erupts underwater and forms rounded lumps or pillow-shaped structures due to the rapid cooling of molten lava when it comes into contact with water. This type of lava flow is commonly found at mid-ocean ridges and submarine volcanoes.
Pillow basalts are indicators that the lava was erupted where?
Pillow basalts are indicators that the lava was erupted underwater or in a marine environment. The cooling process of these lavas forms characteristic pillow-shaped structures as they interact with the water.
What are the three types of lava flows associated with basaltic lava?
basaltic lava can form a'a, pahoehoe, or pillow lava.
How can pillow-shaped bodies form from lava?
as they cool

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.

basaltic lava can form a'a, pahoehoe, or pillow lava.
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 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.
What type of lava that erupts underwater and takes the form of round lumps?
Lava that erupts underwater and takes the form of round lumps is called pillow lava
How hot is pillow lava?
pillow lava is 2500 degrees
