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.

∙ 11y agoYes, they are. Do you want to know informations about Intrusive Rocks? here. Magma that is buried deeply in the earth's crust will cool down slowly.Finally, it will form very large intrusive igneous rocks (or plutonic rocks) They may remain buried in the ground for thousands of years.

∙ 9y agoAn intrusive rock is a type of ingeous rock from the magma below the surface of the Earth. This type of rock is rough not smooth. They are rough because of large crystals.

∙ 9y agoIntrusive rocks have a very course and crystalline texture. They cool deep in the Earth's crust so they have time to rock large crystals.

Which rocks are more likely to have a coarse grained extrusive or intrusive?
extrusive
What is the texture of Intrusive igneous rocks?
An igneous rock has two different textures. Extrusive rocks generally are smooth and glassy. Intrusive rocks are generally coarse
Are plutonic rocks intrusive and generally consist of mineral grains that are coarse enough to be readily visible in a hand sample?
Yes, They Are.
What characteristics are used to classify igneous rocks?
Intrusive and extrusive factors of an igneous rock classify them. The other factors are if they are vesicular, coarse, fine grained, glassy, or very coarse
What rock does magma form when it cools?
Magma forms coarse crystalline intrusive igneous rocks such as granite or gabbro, depending on the chemical composition of the magma.
Intrusive Igneous rocks are characterized by a coarse-grained texture because they contain?
Intrusive igneous rocks commonly have large mineral crystals.
Which rocks are more likely to have a coarse grained extrusive or intrusive?
extrusive
What is the texture of Intrusive igneous rocks?

What do Granite and diorite have in common?
They are both coarse-grained intrusive igneous rocks
What do granite and gabbro have in common?
They are both coarse grained intrusive igneous rocks
How are intrusive igneous rocks made?
They are made slowly. This is why they have a coarse-grained or rough texture. On the other hand there are extrusive igneous rocks, which are formed quuickly. These have a fine-grained or smoother texture. Intrusive rocks have more time to cool, so the mineral crystals can grow bigger, but extrusive rocks have lss time for their mineral crystals to grow.Igneous rocks form when magma cools and hardens.
Are plutonic rocks intrusive and generally consist of mineral grains that are coarse enough to be readily visible in a hand sample?
Yes, They Are.
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.
What is the texture of an intrusive rock?
It is a coarse grained rock if its intrusive.
What is the texture of intrusive rock?
It is a coarse grained rock if its intrusive.

Intrusive and extrusive factors of an igneous rock classify them. The other factors are if they are vesicular, coarse, fine grained, glassy, or very coarse
Why are intrusive rocks coarse grained?
Not all of them are coarse grained, however, in general when magma is intruded into other rocks rather then being extruded onto the earth's surface and cooling in air or water, it cools down more slowly. This slow cooling allows time for crystals to grow and this makes the rocks coarse grained.
