True or false intrusive igneous rock forms small crystals because it cools rapidly?
False
What crystal large or small can help identify an igneous rock as intrusive or extrusive?
As a general rule extrusive igneous rock crystals are very small, often microscopic, as the rock cools very rapidly. Conversely intrusive magma often cools so slowly that sizeable crystals can develop.
Is serpentinite rock extrusive or intrusive?
Syenite - Wikipedia, the free encyclopediaSyenite is a coarse-grained intrusive igneous rockof the same general composition as granite but with the quartz either absent or present in relatively small amounts (
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.
Why does Granite take much longer to form than Basalt?
hmmm, granite is intrusive, formed and cooled slowly at depth with larger individual crystals. Basalt is extrusive, fine grained (small crystals and cooled quickly. The intrusive equivalent of basalt is gabbro. For granite; rhylolite
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.
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
Do extrusive igneous rocks have small grains since intrusive has large?
