False.
Basaltic lava sometimes is erupted under water or flows into the ocean. It makes a formation like a pile of pillows on the sea bottom. Pillow lava crystallizes quickly from the outside to the inside of each "pillow." Lava of this type forms only under water. Pillow lavas are found on many mountains throughout the world.

How Pillow lava is formed?
Pillow lava is formed when hot basaltic lava erupts underwater, typically at mid-ocean ridges or volcanic islands. As the lava flows out and comes into contact with the cold ocean water, it rapidly cools and solidifies, creating a rounded, pillow-like shape. The outer surface solidifies quickly while the interior remains molten, leading to the formation of these distinctive structures. As more lava is expelled, additional layers of pillow lava are created, often resulting in a stacked appearance.
Pillow lavas are associated with?
Pillow lavas are associated with underwater volcanic eruptions, where lava cools rapidly upon contact with water, forming characteristic pillow-like shapes. These formations are common in submarine volcanic environments, such as mid-ocean ridges and seamounts. Pillow lavas provide valuable insights into the Earth's tectonic and volcanic processes.
What type of volcanic material is indicative of eruption under water?
Volcanic material indicative of underwater eruptions includes pillow lava, which forms when lava erupts and cools rapidly upon contact with water. This results in rounded, pillow-like structures that can be found on the ocean floor. Additionally, volcanic ash and tephra can also be produced during underwater eruptions, but the distinct morphology of pillow lava is a key indicator of subaqueous volcanic activity.
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.

What kind of rock forms when lava cools in the ocean?
When lava cools in the ocean, it forms a type of rock called pillow basalt. This distinctive rock gets its name from its pillow-like shape that results from the rapid cooling of lava in water. Pillow basalt is commonly found in areas where underwater volcanic eruptions occur.
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.
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 do you make a box easier to push?
put something with a soft surface such as a pillow under it and push with your back
What are the pillow lavas in new zealand?
Pillow lava are eruptions of volcanic material underwater, and consequently their rapid quenching causes them to form discrete 'pillow' shapes. Commonly 500 to 1000 mm in size. Notable are those at Red Rocks on Wellington's south coast, and at Boatman's harbour in Oamaru. No doubt many other areas as well.
Sealy Firm Support Pillow?
The Sealy firm support pillow offers strength and durability without compromising comfort. The pillow is constructed out of strong spiral sprung polyester fibers that work to provide support to the neck and head. The pillow cover is 300 thread count cotton, ensuring a comfortable surface every night. The pillow is also hypoallergenic and can be easily washed in a machine washer and dryer.
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.
What is the the lava that flows slowly to form a glassy surface with rounded wrinkles?
Pahoehoe or pillow lava - same thing
What do pillow basalts indicate about the environment of volcanism?
Pillow basalts indicate that the volcanic eruption occurred underwater or in a submarine environment. The rapid cooling of lava in water causes it to form characteristic pillow-like shapes. This suggests that the volcano was either located on the ocean floor or erupted into a body of water.
