Discuss on Extrusive Rock Types
Subject: Geography | Topics:

Basic objective of this article is to Discuss on Extrusive Rock Types. The kind of rock an extrusive lava makes is essentially dependent on the chemistry on the venting magma. Basalt, andesite, and rhyolite. Basalt, usually the primary lava to form, contains a high percentage of ferromagnesian nutrients and about 25 to 50 percent silica, making it dark green, gray, or even black.
