There are many different types of ignoues rock, but as a general description, mafic, felsic and intermediate rocks are formd from basaltic, granitic, and andesitic magmas respectively.

Igneous rocks form by what?
Igneous rocks are formed as the result of cooling magmas.
Where does andesite form?
Andesite is an extrusive igneous rock found on or near volcanoes that contain intermediate magmas.
Do granite igneous rock form quickly or slowly?
Granite is the result of slow cooling processes of felsic magmas.
Why some types of magma form igneous rocks that are dark colored and dense.?
Mafic and ultramafic magmas are high in dark, heavy minerals like pyroxene, amphibole, and olivine, which contribute to an igneous rock being dark in color with a higher specific gravity than felsic and intermediate magmas and rocks.
Why are some types of magma form igneous rocks that are dark colored dense?
Mafic and ultramafic magmas are high in dark, heavy minerals like pyroxene, amphibole, and olivine, which contribute to an igneous rock being dark in color with a higher specific gravity than felsic and intermediate magmas and rocks.
What will determine if a rock becomes an igneous or metamorphic rock?
Geological processes form rocks. Igneous rocks are made from magmas. Metamorphic rocks are made by changing the physical environment of a previously existing rock.
What rock families can form magma if hot enough?
All the three existing rock families/types/classes (ie, igneous, sedimentary and metamorphic rocks) can form magma, if they become hot enough to melt and change to molten form.
Explain why some types of magma form igneous rocks that are dark colored and dense?
Mafic and ultramafic magmas are high in dark, heavy minerals like pyroxene, amphibole, and olivine, which contribute to an igneous rock being dark in color with a higher specific gravity than felsic and intermediate magmas and rocks.
What do igneous form from?
An igneous rock has crystallized and solidified from molten rock (magma) either below ground (intrusive igneous rock) or at or near the surface (extrusive igneous rock). Igneous rocks are composed of minerals.
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.
Why are there so many types of magmas?
Because there are so many sources from which these magmas form. Different source rock = different magma composition.
Name the three families of igneous rocks?
This is a very simplistic answer. But, it should reveal the basic processes involved in rock formation.1. Sedimentary, like coal and limestone. They are made from particles of substances that settle and coalesce into a layer that becomes rock.2. Igneous, like granite and basalt. These rocks were formed by heat. Think of lava.3. Metamorphic: Marble and slate. These are rocks that were in another form and got changed by pressure into their present form.
