Igneous rocks may be similar in mineral composition and yet have different?
Texture or crystal size.
One magma can produce several different igneous rocks having different mineral compositions?
Magmatic differentiation results to the formation of several different igneous rocks from a single parent magma. It occurs in nature via crystal settling and squeezing.
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.
What would not be used to classify igneous rocks?
crystal size
Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.
The igneous rock texture characterized by two distinctly different crystal sizes is the texture?
Porphyritic

What is The crystal size of an igneous rock is described as?
texture

What is the difference in crystal growth between intrusive and extrusive igneous rock?
The crystal growth of intrusive igneous is substantially more so than extrusive igneous. Magma cools quicker on the earth's surface, extrusive igneous formed, as opposed to below the crust, intrusive. Therefore the longer it takes to cool the magma, the more the crystal growth.
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.
Write the difference between extrusive and intrusive igneous rocks?
igneous Extrusive is cool on the outside of the crust and cools quickly before crystal forms igneous Intrusive is cool on the inside of the crust and cools slowly and allowing crystal to form
Where would you find igneous rock with the smallest crystal?
at home
What would not be used to classify igneous rocks?
crystal size
What is a xenocryst?
A xenocryst is a crystal which does not occur in a specific igneous rock.
