What else can I help you with?
How can you determine if an igneous rock has had an intrusive or extrusive organ?
by the size of the crystals, big crystals intrusive, small crystals extrusive
Are fine crystals intrusive or extrusive?
extrusive
Is an intrusive crystal bigger than an extrusive crystal?
Typically, intrusive crystals are larger than extrusive crystals because intrusive rocks cool slowly beneath the Earth's surface, allowing larger crystals to form, while extrusive rocks cool quickly at the surface, producing smaller crystals.
What is the comparison of granite and basalt in terms of origin and texture which is intrusive and which is extrusive?
Basalt can't see crystals and basalt is extrusive. Granite you can see the crystals and is intrusive.
What is a black intrusive rock with small crystals?
Intrusive rock normally has visible crystals. Extrusive igneous rock has small crystals. A black extrusive igneous rock with small crystals could be basalt.
Do all intrusive igneous rocks have crystals?
Yes. All intrusive igneours rocks and many extrusive rocks have crystals.
How can you determine if a igneous rock has had an intrusive or extrusive origin?
== Grain size. Most intrusive igneous rocks will have visible crystals. Crystals in most extrusive igneous rocks are not easily visible.
How are intrusive and extrusive rock different?
Intrusive Rocks are found underneath Earths crust, while Extrusive rocks are found above Earths crust.
Which kind of of igneous has more crystals extrusive or intrusive?
instrusive Rock
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.
Is this true or false Intrusive rocks have smaller crystals than extrusive rocks?
Generally, false. Intrusive rocks cool far more slowly than extrusive ones, so the crystals have time to grow larger.
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.
