Yes that is why it makes that glassy look to it.

Obsidian is formed when rapidly cooling ions are randomly distributed creating a?
glassy
Is Obsidian formed when rapidly cooling ions are randomly distributed creating a texture?
Glassy
What is the difference between obsidian and pumice?
Pumice is formed from frothy lava. Obsidian is not. Both have cooled rapidly from lava.
Where is obsidian on the periodic table and which number element is it?
Obsidian is not an element, therefore it does not have an atomic number or a place on the periodic table. Obsidian is a volcanic glass which forms when lava cools rapidly.
Is obsidian an instrusive or extrusive igneous rock how do you know?
Obsidian is an extrusive rock and is formed from rapidly cooling magma. Obsidian is also known as volcanic glass and one can find only sub-microscopic crystals in it. This is because it was cooled too fastly for large crystals to form. If the material that obsidian consists of were an intrusive rock and had a lot of time to cool down, one would find that it would be composed of easily visible crystals.
Do obsidian rocks cool fast?
Obsidian is formed from very rapidly cooling lava.
What rock is black and glassy and rapidly cooling lava?
obsidian
Obsidian is formed when rapidly cooling ions are randomly distributed creating a?
glassy
Is Obsidian formed when rapidly cooling ions are randomly distributed creating a texture?
Glassy
Is pumice and obsidian forms of volcanic gas?
Partially correct. Pumice forms from rapidly cooling lava containing volatiles (water and gas) and obsidian forms from rapidly cooling lava that doesn't contain volatiles. Bubbles from volatiles are frozen in place and cannot escape before the lava hardens forming pumice. Obsidian and pumice are sometimes found together although obsidian itself is relatively rare.
What type of rock had no visible crystals as result of rapid cooling?
Obsidian is an example of a rapidly cooled rock, also known as volcanic glass.
Is obsidian rock metamorphic rock sedimentary or igneous?
Obsidian is an extrusive igneous rock, formed from rapidly cooling lava.
How fast does the lava cool when it is forming an obsidian rock?
Obsidian is formed and cooled so rapidly from lava that it is a glass, not crystalline in structure. The cooling is obviously very rapid and solidification could probably measured in minutes.
How are granite and obsidian are different?
Granite is a rock, whereas obsidian is a type of glass formed by cooling lava.
What is possible origin of obsidian?
Obsidian is volcanic glass, derived from the quick cooling of high silica lava.
Smooth glassy rock that is formed when lava cools?
Obsidian
What is the difference between obsidian and pumice?
Pumice is formed from frothy lava. Obsidian is not. Both have cooled rapidly from lava.
