Why are the crystals in pillow basalt smaller than those in many other examples of basalt?
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.
Why are crystals in pillow basalt smaller then ones in basalt?

What are pieces of evidence of sea floor spreading?
Pieces of evidence for sea floor spreading include the presence of mid-ocean ridges where new crust is formed, symmetric magnetic striping on either side of mid-ocean ridges, age dating of oceanic crust that shows it gets older as it moves away from ridges, and the discovery of pillow basalts and other volcanic rocks on the ocean floor.
Is it true that's if you sleep with a spoon under your pillow it will snow?
There is no scientific evidence to support the belief that sleeping with a spoon under your pillow can influence the weather. Weather patterns are determined by larger atmospheric conditions and not by objects placed under pillows.
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.
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 happen to the magma after being pushed upward and exposed at the surface of the ocean floor?
The lava would form pillow basalts.

What happens to the magma after being pushed upward and exposed at the surface of the ocean floor?
When magma reaches the surface of the ocean floor, it cools and solidifies to form igneous rocks like basalt. The rapid cooling of magma at the surface allows for the formation of characteristic features like pillow basalts and seafloor spreading ridges. Over time, these rocks may become buried, eroded, or further altered by geologic processes.
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.
What is a pillow lava and where can you find one?
A pillow lava is a lava which has been erupted under water. Because of the cooling effect and pressure of the water it forms pillow-like structures which sometimes build up into thick deposits. Ancient deposits can be found all over the world, though newer lavas can be found in areas such as Iceland where a combination of ice caps and volcanism create suitable places for pillows to form.
How can using a neck pillow prevent pain?
A neck pillow is specifically designed to conform to the shape of your neck. The shape creates an environment that is conducive to supporting the neck with proper alignment, reducing pain.
You get mad and you scream into a pillow which interaction sound takes place and how does the sound move?
When you scream into a pillow, the sound waves are muffled and absorbed by the fabric of the pillow, reducing the overall volume. The interaction is a combination of sound absorption and reflection, as some sound may still escape the pillow and be heard in the surrounding environment, albeit at a lower intensity.
