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 are volcanic rocks?
Volcanic rocks are classified as extrusive igneous rocks, forming from the solidification of lava.
Was igneous rocks were classified by their their origin texture and shape?
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.

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?
Intrusive and Extrusive.
What rocks are classified as igneous?
They are rocks formed from magma that cools and crystallizes on the earth surface.
Are rocks classified by were they are found?
Rocks are labeled by 3 groups. Igneous, Metamorphic, and Sedimentary.
Was igneous rocks were classified by their their origin texture and shape?
No, igneous rocks are not classified by their shape. They are primarily classified based on their origin (either intrusive or extrusive) and their texture (coarse-grained, fine-grained, glassy, etc.). Shape or form is not a major factor in the classification of igneous rocks.
