Their crystalline nature.
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
Texture and mineral composition are the two main items used to classify igneous rocks. Texture refers to the size and arrangement of mineral grains, while mineral composition refers to the types of minerals present in the rock.
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.
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.
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.
Neither. Conglomerate is a sedimentary rock. Intrusive and extrusive are descriptive terms used to classify igneous rocks.
Granite is the name of the igneous rock used in monuments.
Color and texture is one way to classify igneous rocks. Another way to do this is modal classification and normative classification.
igneous rock
Household items made of igneous rock include countertops, floor and wall tiles, fireplace surrounds and mantels, and decorative rocks and stones for landscaping. Igneous rocks like granite and basalt are commonly used in these applications due to their durability and resistance to heat and scratching.
Igneous rocks are usually classified by their chemical composition (acidic or basic), and by whether they formed underground (intrusive, characterised by large mineral crystals) or on the surface (extrusive, made of tiny, microscopic crystals). For instance, basalt is a basic, extrusive rock, and granite is an acidic, intrusive rock.
