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.
What else can I help you with?
Would you list intrusive rocks under rocks that form above the ground or below?
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?
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.
Is apatite intrusive or extrusive?
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.
Write the difference between extrusive and intrusive igneous rocks?
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
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
What is the difference between an intrusive and an extrusive igneous rocks?
"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.
What is the difference between the two types of metamorphic rocks?
how is metamorphic rock different than intrusive rock
What is the major difference between intrusive and extrusive rocks is?
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.
Which one has large grains between intrusive and extrusive igneous rocks?
intrusive
What is the major difference between intrusive rocks and extrusive igneous rocks?
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.
How does the rate of cooling influence crystal size of igneous rocks and how does that help you to distinguish between intrusive and extrusive igneous rocks?
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).
Are intrusive igneous rocks heavy or light?
Intrusive rocks are light.
What is the difference between the way intrusive and extrusive igneous is formed?
Intrusive igneous rocks cool beneath the crustal surface. Extrusive cool above the surface - pillow lavas cool below the sea but above the crust.
Are intrusive rocks volcanic?
No. Volcanic rocks are extrusive. Intrusive rocks are sometimes called plutonic.

What is the difference between instrusive rocks and extrusive rocks?
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.
What term describes igneous rocks that crystallize inside the Earth?
Intrusive igneous rocks.
