There is no such thing as an "exclusive" rock. However, there are extrusive rocks. These are divisions of igneous rocks, or rocks that form from molten rock. Intrusive rocks form from molten rock that has cooled underground. They can also be called plutonic rocks. Extrusive rocks, also called volcanic rocks, form from molten rock that has formed at or above the surface.
Intrusive rocks are Igneous rocks that have been formed underground. Igneous rocks are formed by the cooling of lava/magma. Igneous rocks are divided into two categories- intrusive and extrusive. Intrusive is when the magma cools slowly beneath the Earth's surface, which causes large crystals to form. When lava cools above the Earth's surface, it is called extrusive. Extrusive rocks have smaller crystals compared to intrusive, the difference always being noticable.
Igneous rocks are described as intrusive or extrusive based on formation. Intrusive rocks forms underneath the earth surface, while extrusive rocks forms on the surface of earth.
Apatite is typically found as an accessory mineral in both intrusive and extrusive igneous rocks. It is more common in intrusive rocks like granite, but can also be found in extrusive rocks like basalt.
igneous Extrusive is cool on the outside of the crust and cools quickly before crystal forms igneous Intrusive is cool on the inside of the crust and cools slowly and allowing crystal to form
No. Intrusive igneous rocks have large crystals because they cool slowly.
"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.
how is metamorphic rock different than intrusive rock
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
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).
Intrusive rocks are light.
Intrusive igneous rocks cool beneath the crustal surface. Extrusive cool above the surface - pillow lavas cool below the sea but above the crust.
No. Volcanic rocks are extrusive. Intrusive rocks are sometimes called plutonic.

Extrusive rocks form above the surface, cooling quickly and bearing a glassy or fine texture and may be vesicular. Intrusive rocks form below the surface and form slowly, giving it a coarse texture.
