What else can I help you with?
Does obsidian cool quickly or slowly?
it cool quickly but i dont know know how. i have a science homework do tomarrow and i know it cools quickly, but another question is how do you know. i cant just right that i googled it!!!! HELP
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.
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.
What is it called when igneous rocks cool quickly?
obsidian

Do obsidian rock cool quickly?
Yes, obsidian rock cools quickly. It is formed from lava that cools rapidly upon exposure to air or water, preventing the formation of crystal structures. This rapid cooling results in its glassy texture and characteristic smooth surface. As a result, obsidian is considered an extrusive igneous rock.

How obsidian rocks form?
They are formed when either a sedimentary rock or a metamorphic rock are exposed to high heat and turn into magma and then cool quickly.

A black rock formed from cooled lava?
Obsidian
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.

Does obsidian cool fast of slow?
Obsidian cools relatively quickly compared to other volcanic rocks. This rapid cooling occurs when lava cools swiftly upon exposure to air or water, preventing the formation of large crystals. As a result, obsidian has a glassy texture and lacks a crystalline structure, which distinguishes it from other igneous rocks.
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.
