Create an object that is both liquid and solid?
Glass is considered a super cooled liquid.
What is an example of extrusive rock that has cooled too quickly for grains to form?
Obsidian, which is volcanic glass, is a good example.
What igneous rock cooled the most rapidly?
Igneous rocks with very small or no visible crystals are formed by rapid cooling. A good example would be obsidian (which is a volcanic glass) and BAsalt which may have an aphanitic texture (crystals to small to see with the naked eye).
How do igneous rocks with glassy textures form and where?
They form from the extremely rapid cooling of lava or magma. The quick cooling does not allow time for the crystallization of minerals, resulting in the formation of a natural glass.
If lava cools to quickly that ions don't have time to arrange themselves into crystals will form what?
glassy texture, hope this helps :)
What is the igneous rock that cooled too quickly for a crystal structure to form?
Volcanic glass or obsidian is a quickly cooled igneous rock without a mineral crystal structure.
How do Igneous rock with glassy textures?
An igneous rock with a glassy texture cooled from its' liquid state very quickly, an example of this would be obsidian, a volcanic glass.
What is an extrusive igneous rock that is actually glass?
One type of glassy igneous rock is obsidian, which is black and glass-like. Any type of igneous rock that is glassy would be a extrusive rock, which means it was formed outside the earths crust and cooled quickly, making for a fine grain and small crystals. hope this helps
Why does obsidian rock contain no crystals?
obsidian doesnt crystalize because it was formed under water.
What is the difference between an igneous rock with a glassy texture and one with a fine texture?
The main difference is that the glassy textured igneous rock cooled from lava with extreme quickness, while the one with a fine texture cooled less quickly. Obsidian is a natural glass, created by rapidly cooling lava, where mineral crystals do not have enough time to form before the lava solidifies.
Which rock looks like glass if it is cooled quickly?
your thinking of lava rocks probably
What type of matter is glass?
Glass is a solid. It is melted silicon that has cooled quickly. A mineral that cools slowly can become a crystal.
What is the name given to the volcanic glass that forms due to very rapid cooling of magma?
Yes obsidian is glassy because it cooled very fast.
Why glass is called a super cooled liquid?
The definition of glass is a super cooled liquid. Any liquid that is super cooled takes on the properties of glass. Glass as you think of it is just super cooled silica. What happens is that it is cooled so quickly that it doesn't actually undergo a phase change back to a solid. In reality glass is just an incredibly slow moving liquid.
Create an object that is both liquid and solid?
Glass is considered a super cooled liquid.
How is obisidian formed?
Obisidian is formed when resedue from an active volcanco is cooled rapidly. Obisidian is an extrusive igneous rock made of a glass like substance formed from naturally occuring volcanic glass.
Where is az can i find obsidian glass or rocks?
You'll find obsidian by volcanoes where the magma cooled ultra-quickly.
