Pillow basalt is formed from solidifying lava which erupts under the surface of a body of water. Because of this, it cools much faster, allowing less time for crystal growth.
A factor that determines crystal size in igneous rocks is the speed in which the lava/ magma crystallised or froze. As pillow basalts form at mid ocean ridges where magma is erupted into direct contact with the cold sea water the crystals form very fast and are therefore small. Other basalts erupted on land still have relatively small crystals and crystallised relatively fast but overall slower then pillow basalts.
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.
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.
Yes, pillow basalt forms when lava erupts at the surface of underwater volcanoes or mid-ocean ridges, where it rapidly cools and solidifies in an underwater environment. The lava's rapid cooling causes it to form characteristic pillow-shaped structures, resembling stacked pillows. This process is common in areas where volcanic activity occurs beneath the ocean's surface.
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.
Pillow basalt is formed from solidifying lava which erupts under the surface of a body of water. Because of this, it cools much faster, allowing less time for crystal growth.
Crystals in pillow basalt are typically smaller than those in basalt because the rapid cooling that occurs when lava interacts with water during volcanic eruptions inhibits crystal growth. This rapid cooling results in the formation of fine-grained crystals, whereas in basalt, which cools more slowly underground, larger crystals have time to grow.
The crystals in pillow basalt are smaller because the lava cools rapidly when it comes into contact with water, preventing large crystals from forming. The quick cooling process limits the time available for mineral crystals to grow to a larger size, resulting in fine-grained basalt with small crystals.

Pillow basalt forms underwater. Water absorbs heat from lava much more quickly than air does.

Pillows is the plural form of pillow.
No. Granite and basalt have different compositions and form under different circumstances.
