Is Felsic a Intrusive or Extrusive Rock?
It can be either. The term felsic describes the composition of the rock, not where it forms. The general category for intrusive felsic rock is granite while extrusive felsic rock is rhyolite.
What is an example of an extrusive igneous rock?
Basalt and rhyolite are examples of extrusive igneous rocks. Also, pumice, scoria, obsidian, tuff, ignimbrite,....
What are two types of igneous rock?
Two types of igneous rock are intrusive (also called plutonic) and extrusive. There is also porphyry rock which is partly intrusive and partly extrusive. Porphyry rock has large crystals embedded in a mass of much smaller crystals. The large crystals formed underground as does intrusive rock, and were carried in lava when it erupted. The mass of smaller crystals formed around the large crystals when the lava cooled quickly above ground, as does extrusive rock.
Is dacite intrusive or extrusive?
Dacite is extrusive. Its intrusive equivalent is granodiorite.
Is obsidian a intrusive or extrusive igneous rock?
Andesite is considered an extrusive igneous rock.

Extrusive. Solidifies above ground level.
Is diorite intrusive or extrusive?

How are intrusive and extrusive classified?
Intrusive or extrusive describe properties of an igneous rock. An intrusive rock is formed within the crust and it insulated and cooled slowly. Some examples of an intrusive rock include diorite, granite, gabbro, and periodite. They have large grains because they have more time for growth. On the other hand, extrusive rocks cool at the surface rapidly. They are comprised of tiny crystals and/or glass. Some examples include rhyolite, andesite, and basalt.
