Igneous rocks are classified into two main categories: intrusive (or plutonic) and extrusive (or volcanic) rocks. Intrusive igneous rocks form from the slow cooling and solidification of magma beneath the Earth's surface, resulting in larger crystals, while extrusive igneous rocks form from the rapid cooling of lava at the surface, leading to smaller crystals. Additionally, they can be further categorized based on their mineral composition into felsic, intermediate, mafic, and ultramafic types.
What else can I help you with?
Are rocks classified by were they are found?
Rocks are labeled by 3 groups. Igneous, Metamorphic, and Sedimentary.
How do you classify igneous rocks?
Look at them. There shape, size, color and feel! Dont worry you will figure it out....
How are rocks related to minerals What is the difference in how rocks and minerals are classified?
A rock is an agglomeration of different minerals. Minerals are classified into categories based on their chemistry: oxides, sulphides, silicates, carbonates etc. Rocks are classified primarily by the process that formed them: igneous, sedimentary, or metamorphic.
What do intrusive rock have in common with extrusive rocks?
Sedimentary rocks are not classified by the terms intrusive or extrusive. These are terms used specifically for igneous rock classification, referring to rock that has formed from melt either below or on the surface.
What is in the formation of igneous rocks but not in formation of metamorphic rocks?
igneous rocks form within earths surface
How are igneous rocks classified acording to their..?
Igneous rocks are classified by either being intrusive or extrusive, then mafic or felsic then they are classified by either fine grain or course grained textures.
Rocks that originated from the liquid phase are classified as?
Igneous rocks are classified as rocks that originated from the liquid phase, specifically from the cooling and solidification of magma or lava.
How are rocks physically classified?
they are classified into 3 major kinds of rocksthey are the ;IGNEOUS ROCKS,SEDIMENTARY ROCKS,AND METAMORPHIC ROCKS
what are igneous rock classified based upon?
Igneous rocks can be classified by their method of formation and by their mineralogy.
What rocks are classified as?
Mantle rock is classified as ultramafic igneous rock.
Igneous rocks that result when lava solidifies are classified as what?
Igneous rocks that result from lava solidifying above ground are classified as extrusive igneous rocks. These rocks cool quickly, leading to small mineral grains and a fine-grained texture. Examples include basalt and rhyolite.
WHAT ARE Mantle rocks classified as?
Mantle rock is classified as ultramafic igneous rock.
What are volcanic rocks?
Volcanic rocks are classified as extrusive igneous rocks, forming from the solidification of lava.
Are igneous rocks classified by there origen texture and shape?
yes
Igneous rocks can be classified into which 2 groups?
