What is igneous rock?
Igneous rock is one of the three main rock types based on the method of its formation. It is also referred to as plutonic or volcanic rock depending on where it formed. In a nutshell, to be classified as igneous, a rock must have crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock).
Name three exsmples of igneous rocks?
Igneous Rocks - Rocks formed by crystallization from a melt (magma) types are: # Extrusive (volcanic) - produced when magma flows on the earth's surface # Intrusive (plutonic) - produced when magma solidifies at depth beneath the earth. eg.s are: 1)pumice. 2)Laccolith 3)Batholith 4)Dike 5)Sill
What are three types of igneous rock?
Three types of igneous rocks are pumice, basalt, and granite.
The three rock groups are classified?
Igneous: These rocks are volcanic in nature. They are split into two categories in where they cool/crystallize: intrusive (internal) and extrusive (external). Intrusive volcanic rocks cool slowly, so they contain (usually) large crystals, like granites. Extrusive rocks are quite the opposite, in which they cool very quickly. This is where you get your obsidian glass and basalts. Sedimentary: These rocks are depositional and categorized by the kind of sediment it is made up of. Metamorphic: This can be the offspring rock of either a morphosed igneous or sedimentary rock. This metamorphism is accomplished by heat and/or pressure, and during a great length of time.
What types igneous rocks do not belong to any of the three major igneous rocks families?
granodiorite, pyroxentite,dunite, and periodite rocks do not belong in the three major igneous rock families.
What are three methods of intrusive igneous rock formation?
There are three methods of intrusive igneous rock formation. Igneous rock can form at mid ocean ridges, subduction zones, and at the continental crust if it is pushed together.
Describe granite using the three characteristics geologists use to classify igneous rocks?
Granite is a felsic, coarse grained, intrusive igneous rock.
Which types of igneous rocks are composed of at least 50 percent olivine?
There are three intrusive igneous rocks that are composed of at least 50% olivine. These rocks are peridotite, kimberlite and dunite.
what is the definition of an Intrusive igneous rock?
Igneous rock, formed in the Earth's crust where it cools and solidifies within pre-existing rocks. The magma cools very slowly over thousands, and/or millions of years until fully solidified. Three examples of intrusive rocks are Diorite, Granite, and Pegmatite.

What does ingeous mean?
Solidified magma or lava.Igneous rock (derived from the Latin word ignis meaning fire)Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
What are the types of volcanic rocks?
Igneous rocks exhibit three types of textures: coarse grained (intrusive), fine grained (extrusive), and porphyritic (two-stage solidification of mineral constituents). Chemically, they are categorized as felsic, mafic, or intermediate.

What is the name of igneos rock?
Igneous rock (etymology from Latin ignis, fire) is one of the three main rock types. Igneous rock is formed by magma (molten rock) being cooled and becoming solid. They may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
What are the three families of igneous rocks?
the three rock families are igneous rock, metamorphic rock, and sedimentary rock

There are three types of rock on the face of the Earth. The three rocks are sedimentary, metamorphic, and igneous.
