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.

How can a rock composition help geologists to classify the rock?
tell me the answer I'm the one asked it
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
How igneous rock classified?
Geologists classify rocks by where they are formed; above ground or under ground
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.
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.
List four ways geologists classify rocks?
Geologists classify rocks based on their origin (igneous, sedimentary, metamorphic), mineral composition, texture, and mode of formation.
Who studied 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 is the chemical property used to classify igneous rocks?
The chemical property used to classify igneous rocks is their mineral composition, specifically the type and relative abundance of minerals present in the rock. This information helps geologists differentiate between different types of igneous rocks, such as basalt, granite, and rhyolite.
How do geologists classify rock?
Geologists classify rocks into three groups. The first group are igneous rocks, the second are metamorphic rocks and the third are sedimentary rocks.

How do geologists classify metamorphic rock?
Geologists classify metamorphic rocks by the arrangements of the grains that make up the rocks.
Do geologists classify metamorphic rocks by the arrangement of grains making up the rock?
Yes.

How do geologists classify rock samples from the Eath's crust?
By their provenance, appearance, texture and mineralogy.
What are the three groups into which geologist classify rock?
Metamorphic, igneous and sedimentary
What three things do geologist classify rocks based on?
Geologists classify rocks based on their origin (igneous, sedimentary, metamorphic), mineral composition, and texture. These three factors help geologists understand how the rock formed and the conditions it has been subjected to.
