Does the obsidian cool quickly?
Obsidian cools relatively quickly compared to other types of volcanic glass due to its composition and the rapid cooling process during its formation. The rate of cooling affects the crystal structure and appearance of the obsidian, leading to its characteristic smooth and glassy texture.
Did obsidian cool quickly or slowly?
Obsidian cooled very quickly. It's a vulcanic glass, meaning that the crystals are so small, they had virtually no time to form an orderly crystalline texture, and are basically placed randomly. Smaller grain size is associated with faster cooling.
Some extrusive igneous rocks such as obsidian are glassy because they?
cool too quickly for mineral grains to form, resulting in a non-crystalline structure.
Igneous rocks that cool quickly on earth surface are?
Igneous rocks that cool quickly on the Earth's surface are called extrusive or volcanic rocks. Examples include basalt, obsidian, and pumice. These rocks have fine-grained textures due to their rapid cooling.
How some extrusive igneous rocks such as obsidian are glassy is because they?
cool very quickly, preventing mineral crystals from forming. This rapid cooling process solidifies the lava before crystals have a chance to develop, resulting in a smooth, glassy texture. The lack of mineral crystals gives obsidian its unique appearance and properties.
What is it called when igneous rocks cool quickly?
obsidian
Does the obsidian cool quickly?

Does Dunite cool quickly or slowly?
slowly
Does the biotite rock cool quickly or slowly?
slowly
What is the origin of obsiadan?
If you are asking about how they were formed magma from volcano that are shot in the air of quickly spewed out causing the magma to cool very quickly forming a very smooth surface on obsidian. Becuase the magma cooled so fast it couldn't slowly cool into a rough textured rock.
What property of a surface determines how quickly or slowly it will heat and cool?
The thermal conductivity and color of a surface determines how quickly or slowly it will heat and cool
Some extrusive igneous rocks such as obsidian are glassy because they are what?
They cool to quickly for crystals to form.
Did obsidian cool quickly or slowly?

What is the term when magma cool slowly then cools quickly?
I cant tell!
Some extrusive igneous rocks such as obsidian are glassy because they?
cool too quickly for mineral grains to form, resulting in a non-crystalline structure.
Could phenocrysts be found in an obsidian?
No, phenocrysts are typically minerals that form in slowly cooling magma and are therefore not found in obsidian, which is a type of igneous rock that cools quickly, resulting in a glassy texture without crystal growth.
Does andesite cool quickly or slowly?
Lava will cool quickly compared to underground magma.
