density
Intrusive rocks are formed from cooling magma beneath the surface. The opposite would be an extrusive rock, these rocks form from lava cooling on the surface of the earth.
Intrusive igneous rock.
Lava flows cool rapidly compared to the cooling of rocks underground. The slower cooling time of intrusive igneous rocks allows larger crystal formation. Generally, the more cooling time, the larger the crystals.
Granite and basalt are the most common types of igneous rock. Igneous rock types, or classifications, also include those that are intrusive and extrusive. Intrusive igneous rock is formed from the solidification of slow cooling magma below the surface. Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.
Granite is classified as an intrusive igneous rock.
Crystal
Im assuming density.
Intrusive rick forms when the cooling and solidification of magma and extrusive is when the cooling and solidification of lava.
Intrusive rocks are formed by the cristalization and cooling of magma deep inside the Earth.
Intrusive rocks are formed from cooling magma beneath the surface. The opposite would be an extrusive rock, these rocks form from lava cooling on the surface of the earth.
Intrusive igneous rocks are formed by the cooling of magma.
intrusive
An intrusive igneous rock is formed by the gradual cooling, solidification, and crystallization of magma within the earths crust/interior.
Intrusive igneous rock.
They form underground from the cooling and solidification of magma.
Magma cooling beneath the surface creates intrusive igneous rocks.
Lava flows cool rapidly compared to the cooling of rocks underground. The slower cooling time of intrusive igneous rocks allows larger crystal formation. Generally, the more cooling time, the larger the crystals.
