What else can I help you with?
Are intrusive rocks rough and coarse?
Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. A rock with larger mineral crystals is said to have a coarse texture.
A type of intrusive igneous rock with larg crystals?
Basically, all intrusive igneous rocks have large crystals. Because they are intrusive, they take a long time to cool down, and so there is a lot of time for crystal growth. That said, the biggest categories of intrusive igneous rocks are: Peridotite (ultramafic) Gabbro (mafic) Diorite (Intermediate) Granite (silicic/felsic) Granite is the most common one in the continental crust.
What type of crystals form in intrusive rocks?
large,well developed crystals.This is because of slow cooling process
What rock type is formed from the slow cooling of magma under the earths surface?
Magma cooling beneath the surface creates intrusive igneous rocks.
What igneous rock forms deep underground from cooled lava?
When magma cools underground, it creates intrusive rocks (intrusive=inside the earth). Intrusive rocks are coarse-grained and have visible mineral crystals. This happens because the magma cools slowly over a long period of time, giving these crystals time enough to form in a visible fashion. On the other end, we have extrusive rocks. These cool at the surface and have much smaller, usually 'invisible' crystals. This happens because the magma cools much, much faster, which of course doesn't give the crystals ample time to form.
What are minerals that form in intrusive rock?
I dont know but an intrusive rock is a type of igneos rock
What is a felsic intrusive rock?
A felsic intrusive rock is a type of igneous rock that is rich in silica and aluminum minerals. These rocks form from the slow cooling of magma below the Earth's surface, allowing large mineral crystals to develop. Granite is a common example of a felsic intrusive rock.
What type of rock can be extrusive or intrusive?
Igneous rocks can be either extrusive or intrusive. Extrusive igneous rocks form from lava cooling quickly on or near the Earth's surface, resulting in small crystals. Intrusive igneous rocks form from magma cooling slowly beneath the Earth's surface, resulting in larger crystals.
An intrusive igneous rock will have what type of texture?
Intrusive igneous rock has a coarse, visible crystalline texture. Intrusive igneous rocks are formed from slow cooling of magma. The additional time spent in a liquid state allows for the creation of larger mineral crystals. An igneous rock with a coarse texture is said to be phaneritic.
Are intrusive rocks rough and coarse?

What type of rock can only form below earths surface?
MetamorphicPlutonic rocks, (Intrusive igneous rocks).
Is intrusive rock is also called platonic rock?
No, intrusive rock is not also called platonic rock. Plutonic rock is another name for this type of rock, which is produced by magma.

Where did an igneous rock form if the rock contains large crystals?
Usually from the slow cooling of magma with a plentiful supply of material necessary for crystal growth, and space in which to grow.
