A rock with large crystals scattered on a background of much smaller crystals is called a porphyry. This rock texture is the result of two stages of cooling, where large crystals formed during the slower cooling stage, followed by smaller crystals forming during rapid cooling.
The type of rock formed from lava cooling quickly is called basalt. Basalt is a fine-grained igneous rock that is commonly found in volcanic regions and has a dark color due to its rapid cooling process.
The mafic rock that is full of holes and made of dense materials is basalt. Basalt is formed from lava that has rapid cooling, which traps gas bubbles inside the rock.
Igneous rock, specifically basalt, is formed when lava cools quickly. Basalt is characterized by its fine-grained texture due to rapid cooling at the Earth's surface.
The size of crystals decreases as the cooling increases. This is called an inverse relationship.
Vesicles.
The rock is said to be extrusive or possess an aphanitic texture, as a result of relatively rapid cooling.
Fine-grained
A rock with large crystals scattered on a background of much smaller crystals is called a porphyry. This rock texture is the result of two stages of cooling, where large crystals formed during the slower cooling stage, followed by smaller crystals forming during rapid cooling.
If the cooling is rapid, it can trap gas bubbles within a material, leading to internal stresses and potential cracking. Rapid cooling can also result in a material not achieving its desired strength or structure, affecting its overall performance and longevity. It may also impact the material's physical properties and make it more brittle.

Obsidian is an example of a rapidly cooled rock, also known as volcanic glass.
rapid cooling
no . they come from rapid cooling lava
Yes, fast cooling can result in the formation of smaller grains in a material. Rapid cooling can limit the time available for atoms to arrange themselves into larger crystal structures, leading to the formation of smaller grains with more boundaries.
Pumice is simply a frothy, gas entrained volcanic glass, a result of the extremely rapid cooling of felsic lava after eruption.
