Metamorphic, igneous and sedimentary
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.
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
Extrusive igneous rocks have very small crystal grains.
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.

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.
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.

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.

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.
