How do geologists classify igneous rock?
Geologists classify rocks by where they are formed; above ground or under ground
What are the three groups into which geologist classify rock?
Metamorphic, igneous and sedimentary
What characteristics are used to classify igneous rocks?
Intrusive and extrusive factors of an igneous rock classify them. The other factors are if they are vesicular, coarse, fine grained, glassy, or very coarse
What Evidence Would You Look For If Attempting To Classify A Piece of igneous Rock as Extrusive?
Extrusive igneous rocks have very small crystal grains.
What type of igneous rocks are easy to classify because the minerals that they contain can be seen and identified?
Crystals are easy to classify because the minerals that they contain are easily identified. One example of this would be emeralds. Another example of a crystal is a diamond.

How do you classify an igneous metamorphic and sedimentary rock?
Investigate what they look like, where you found them, and how they were formef
One of two items used to classify igneous rock?
Their crystalline nature.
Who studies igneous rock?
Geologists study the rocks that compose the earth or other terrestrial planets. Mineralogists classify and name types of lava. Stone cutters study granite , which is an igneous rock.

Extrusive igneous rocks have very small crystal grains.
What chemical property is most commonly used to classify igneous rock?
The percentage of its composition of silica.
Would mineral content classify an igneous rock?
No -- it's a type of rock, often a composite. Primay types are igneous (made by fire -- vulcanism), sedimentary (sea beds) and composite (a mixture of other types). In almost every case, all of these types are defined as how the substance at hand was created and in most cases they are not pure minerals.
Describe granite using the three characteristics geologists use to classify igneous rocks?
Granite is a felsic, coarse grained, intrusive igneous rock.
How do scientists classify intrusive igneous features?
according to shape, size, and their relationship to surrounding layers of rock
What refers to the size of the crystals evident in the rock and is the property you use to classify igneous rocks is?
intrusive and extrusive
