What are the three groups into which geologist classify rock?
Metamorphic, igneous and sedimentary
What type of igneous rocks are easy to classify because the minerals that they contain can be seen and identified?
Rocks with large, easily identifiable minerals, such as granite and diorite, are easy to classify. These rocks belong to the intrusive igneous rock category and typically have distinct mineral compositions that allow for easy identification.
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.
How do geologists classify igneous rock?
Geologists classify igneous rocks based on their mineral composition, texture (grain size and arrangement of crystals), and overall chemical composition. Igneous rocks are further categorized as intrusive (formed below the Earth's surface) or extrusive (formed on the Earth's surface) based on where they solidified.

One of two items used to classify igneous rock?
Their crystalline nature.
How do you classify an igneous metamorphic and sedimentary rock?
Investigate what they look like, where you found them, and how they were formef
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.
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.
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.
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
What would not be used to classify igneous rocks?
Color, as it is not a reliable indicator due to variations within the same type of rock. Texture, mineral composition, and formation conditions are typically used to classify igneous rocks.
How would you classify a rock that has even amount of silica iron and magnesium?

What chemical property is most commonly used to classify igneous rock?
The mineral composition (silica content) is the chemical property most commonly used to classify igneous rocks. This can help differentiate between different types of igneous rocks, such as basalt, andesite, and granite.
