What else can I help you with?
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
What type of igneous rock has large mineral grains?
Intrusive igneous rocks since they have more time to cool, thus more time for the crystals o form and grow. So, examples of such igneous rocks will include:-Granite-Gabbro
Do extrusive rocks have larger grains than intrusive rocks?
No, extrusive rocks typically have smaller grains than intrusive rocks. Extrusive rocks form from lava that cools quickly on the Earth's surface, resulting in fine-grained or glassy textures. In contrast, intrusive rocks form from magma that cools slowly beneath the surface, allowing larger crystals to develop. Thus, intrusive rocks generally have larger grains compared to extrusive rocks.
Igneous rocks with large crystals?
Igneous rocks with large crystals are known as intrusive or plutonic rocks. These rocks form underground as magma cools slowly, allowing large crystals to grow. Common examples include granite and diorite.
What are large grains of intrusive rock that cools down slowly?
Large grains of intrusive rock that cool down slowly are called phaneritic. This indicates that the individual mineral grains are visible to the naked eye. Examples of phaneritic rocks include granite and diorite.
Do intrusive rocks have large crystals because they cool quickly?
No. Intrusive igneous rocks have large crystals because they cool slowly.
Which one has large grains between intrusive and extrusive igneous rocks?
intrusive
Which igneous rocks would contain the largest crystals?
Pegmatite. Individual crystals can be as large as a bathtub. Pegmatites are the last rocks to crystallize from a solidifying body of magma. The large size of the crystals results from the slow rate of cooling and the presence of large amounts of water dissolved in the magma.

Do you think extrusive or intrusive igneous rocks are likely to have larger crystals?
If a rock has large crystals, it is an intrusive rock. Intrusive rocks form underneath the Earth's surface. Magma cools slowly so it has time to form large crystals. An example is granite, where you can see the crystals with your naked eye. Rocks that have small crystals are extrusive rocks. Extrusive rocks are ones that form from lava (blasted out of a volcano) so they cool very quickly, not allowing large crystals to form. An example is obsidian, where you cannot visibly see the small crystals; it just looks like one black, glassy rock.
Do extrusive igneous rocks have small grains since intrusive has large?
That is correct.
Do all intrusive igneous rocks have crystals?
Yes. All intrusive igneours rocks and many extrusive rocks have crystals.
Are large crystals intrusive or extrusive igneous rock?
Large crystals are typically characteristic of intrusive igneous rocks, which form beneath the Earth's surface from slow cooling of magma. Extrusive igneous rocks cool quickly at or near the Earth's surface, resulting in smaller crystals or glassy textures.
Igneous rocks with large crystals?
Igneous rocks with large crystals are known as intrusive or plutonic rocks. These rocks form underground as magma cools slowly, allowing large crystals to grow. Common examples include granite and diorite.

Are igneous rocks formed from smalll minerals?
Not necessarily. Intrusive igneous rocks, especially pegmatites, can have large crystals.
