Difference in temperature of the varying layers of the Earth's surface where either of the rocks solidify,causes difference in size of grains of rocks.When solidified below the Earth's surface,the grains are comparatively larger crystals than extrusive igneous ones.Intrusive rocks form underneath the Earth's surface(eg.,granite). Magma cools slowly so it has time to form large crystals.Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form(eg.,obsidian).
Intrusive properties of matter refer to characteristics that are exhibited within a substance, such as density or specific heat. Extrusive properties, on the other hand, pertain to features that are observed at the surface or interface of a substance, like color or texture.
The major difference is their formation location: intrusive rocks are formed below the Earth's surface from the slow cooling of magma, resulting in coarse-grained textures, while extrusive rocks are formed on the Earth's surface from rapid cooling of lava, resulting in fine-grained textures. Intrusive rocks have larger mineral grains due to their slower cooling process, whereas extrusive rocks have smaller mineral grains due to their faster cooling process.
The longer that magma is able to cool, the larger the crystals will be. Intrusive rocks will have larger crystals than extrusive rocks. For example granite (intrusive) has larger grains than rhyolite (extrusive).
GRAPHITE is a native mineral. It is metamorphic and it is effectively the highest grade of coal.
Extrusive igneous rocks are formed from lava that cools quickly on the Earth's surface, resulting in fine-grained textures. Intrusive igneous rocks are formed from magma that cools slowly beneath the Earth's surface, resulting in coarse-grained textures.
"intrusive" means forced into something, "extrusive" means forced out onto the surface. The igneous magma reaching the surface is therefore extrusive , producing extrusive igneous rocks, and all the rest of the magma is intrusive, producing intrusive igneous rocks.
Extrusive means that the lava has come out and cooled on the surface. Intrusive means that the lava has cooled in the Earth i.e. underground.
intrusive
Intrusive igneous rocks cool beneath the crustal surface. Extrusive cool above the surface - pillow lavas cool below the sea but above the crust.
What is the difference between intrusive and intrusive.
The crystal growth of intrusive igneous is substantially more so than extrusive igneous. Magma cools quicker on the earth's surface, extrusive igneous formed, as opposed to below the crust, intrusive. Therefore the longer it takes to cool the magma, the more the crystal growth.
instrusive is inside the valcano and exstrusive comes onto earth's crust
Intrusive: An intrusive igneous rock is formed from magma undergroundExtrusive: An extrusive igneous rock is formed from lava outside of the volcano.
