Is the process of turning sand to glass irreversible?
No, but it can be broken up to be similar. : )
How Do Glassy Texture Igneous Rocks Form?
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.
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.
What are characteristics of basaltic igneous rock?
mainly glassy with amygdules and glass
What is a very light igneous rock honeycomed volcanic glass?
Pumice
What do obsidian pumice rhyolite and granite have in common?
They are similar in composition
How is sweat forming on a glass of ice water similar to cloud formation?
They are both performing Condensation

What tectonic activity leads to the formation of obsidian?
Obsidian is an igneous rock, so it forms from the tectonic activity of an eruption of a volcano. It is a special igneous rock because it is a glass. It forms from an explosive eruption (due to high viscosity and gas content of the magma, which usually is a rhyolitic or andesitic magma). The formation of obsidian is due to the phenomenon of the lava cooling very rapidly that the atoms have no time to arrange themselves in a crystalline structure. So the product is glass.

What is the difference between intrusive and igneous rocks?
The difference between an Extrusive and Intrusive igneous rock is the way in which they cool. An Extrusive igneous rock cools very fast on the surface and is created by lava. Since the cooling process is very fast extrusive igneous rocks have very small crystals (fine grained). On the other hand an Intrusive igneous rock cools very slowly beneath the surface and is created by magma. Since the cooling process is very slow intrusive igneous rocks have very large crystals (coarse grained). In some instances there is also a third type of igneous rock. Technically it is an extrusive rock, but it resembles glass. This glass type of igneous rock forms when magma/lava is instantly cooled.

What igneous rock does not have any minerals in it?
Obsidian is an igneous rock that technically is not composed of minerals. It is a natural glass.
What is the obsidian rock type?
Obsidian is an extrusive felsic igneous rock.
What igneous rock has a smooth glass like texture?
Obsidian
Is glass made out of igneous rock?
no, sedimentry, namely sand
Do igneous rocks have crystals in them?
Not all of them. Volcanic glass does not have crystals.
