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
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.
Extrusive igneous rocks have smaller crystals due to rapid cooling on the Earth's surface, while intrusive igneous rocks have larger crystals due to slower cooling beneath the Earth's surface. This difference in crystal size can help distinguish between the two types of rocks.
It's very rare to have an extrusive Peridotite, but under the right conditions Komatite can form. It's similar in appearance to Basalt, but has long ( anywhere between 1-10 cm) criss-crossing needles of olivine or pyroxene.
Both are formed from the solidification of cooling magma.
"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.

Intrusive: An intrusive igneous rock is formed from magma undergroundExtrusive: An extrusive igneous rock is formed from lava outside of the volcano.

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).
