porous rocks called igneous rocks
Extrusive igneous rock is formed from the solidification of lava.Intrusive igneous rock is formed from the solidification of magma.
Igneous rocks are formed by the solidification of molten materials.
Produced under conditions involving intense heat, igneous rock is rock formed by solidification from a molten state, especially from molten magma. an igneous rock is a lava rock that has cooled!
A few billion years ago, when the Moon was young and it was hotter than it is now, there was molten rock inside. This lead to the formation of igneous rocks on the surface.
porous rocks called igneous rocks
Rocks are formed from the solidification of molten magma, from the erosion and consolidation of eroded rock, or from the sedimentation of organic matter. Rocks are composed of minerals. Minerals are combinations of elements and are formed in response to many factors which include temperature, pressure, and element availability.
The first rocks were igneous, formed from the solidification of magma on the once molten Earth.
Igneous rock can form inside the Earth or on its surface, from the solidification of molten rock.
Extrusive igneous rock is formed from the solidification of lava.Intrusive igneous rock is formed from the solidification of magma.
Igneous rock forms from the cooling of molten material called magma or lava.
It doesn't necessarily matter what the minerals are, as long as they form from cooling magma or lava. Igneous rocks are formed by the solidification of cooled magma (molten rock). They may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.
"Igneous rocks (etymology from Latin ignis, fire) are rocks formed by solidification of cooled magma (molten rock)" ~Wikipedia.comSee Related Links below.
Igneous rocks are formed from the cooling and solidification of magma or lava.
