Pillow lava is associated with submarine basaltic eruptions. Although they are usually basaltic, they can have other compositions as well.

When Lava cools underwater what usually forms?
Submarine volcanoes / Pillow lavas.
What kind of rock forms when lava cools in the ocean?
igneous rock
Are Basaltic lavas are generally hotter and more viscous than andesite lavas?
No. Basaltic lavas are hotter and less viscous than andesitic lavas.
Are Basaltic lavas generally hotter and more viscous than andesite lavas?
Basaltic lavas are hotter, but less viscous than andesitic lavas.
Pillow basalt originates at the surface of volcanic islands?
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.

What rocks are formed under water?
Sedimentary Rocks Don't forget pillow lavas, and water-chilled lavas. Mid-ocean ridge rocks are surely worth a mention. And flow silicates such as the 'Pink and White terraces' and similar elsewhere in the world.
What is the closest to the center of a spreading axis on the sea floor carbonate ooze silceous pillow lavas or turbidites?
Some thing that ha an ending too it self.

What is associated with a teenage girls sleepover?
Pillow fights. I think.
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.
What is fluid lava?
Very fluid lavas have low viscosity. Lavas decrease in viscosity with lessening amounts of silicon. Mafic lavas are lower in silicon and therefore more fluid in nature.
Is the composition of the hawaiian lavas felsic or mafic?
Hawaiian lavas are mafic.
Why are the Crystal's in pillow basalt smaller than those of in other example of basalt?
Pillow basalts are lavas that were erupted and cooled in sea water. Therefore, they have had very little time to form crystals of any size, during rapid solidification, when compared to most land or air-born eruptions.
