What do intrusive rock have in common with extrusive rocks?
Sedimentary rocks are not classified by the terms intrusive or extrusive. These are terms used specifically for igneous rock classification, referring to rock that has formed from melt either below or on the surface.
Is silica intrusive or extrusive?
The terms intrusive and extrusive apply to the formation of igneous rocks. Silica is a chemical component of a wide variety of minerals found in many types of igneous, metamorphic, and sedimentary rock. All igneous rocks, both intrusive and extrusive, contain silica.
Is gabbro an intrusive or extrusive?
Intrusive Igneous Rock , it is because gabbro has a very rough texture.Intrusive cools slowly and extrusive cools rapidly.
Can the minerals which form an intrusive rock also form the same rock but is an extrusive rock?
Yes. For example gabbro and basalt are chemically equivalent (and so are composed of the same minerals), however gabbro is intrusive and basalt is extrusive.
Is gabbro an intrusive or extrusive igneous rock?
Gabbro is an intrusive igneous rock, whick means that it was formed under ground.
Which intrusive and extrusive rocks have the same chemical composition?
Intrusive: Extrusive Equivalent Granite: Rhyolite Diorite: Andesite Gabbro: Basalt
Are mafic rocks solely intrusive or extrusive?
No. The terms felsic and mafic refers to the relative content of certain minerals in the magma or rock. A mafic rock can be extrusive like basalt, or intrusive like gabbro. Basalt and gabbro can be identical in chemical composition.
What is the difference between gabbro and basalt?
Gabbro is a coarse-grained, intrusive igneous rock composed mainly of calcium-rich plagioclase feldspar, pyroxene, and sometimes olivine. Basalt, on the other hand, is a fine-grained, extrusive igneous rock composed mainly of plagioclase feldspar and pyroxene. Basalt is typically found on the Earth's surface, while gabbro is usually found beneath the surface as intrusive rock formations.
Which of the six major kinds of rock are intrusive and which are extrusive?
Intrusive rocks are formed beneath the Earth's surface and include granite, diorite, and gabbro. Extrusive rocks, on the other hand, are formed on the Earth's surface and include basalt, andesite, and rhyolite.
Is gabbro volcanic?
No. Gabbro is an intrusive igneous rock.
Is basalt an intrusive rock or extrusive rock?
Extrusive. Solidifies above ground level.
Is schist an intrusive or extrusive rock?
Neither, Igneous rock is either intrusive or extrusive. Thats what intrusive and extrusive is... A igneous rock.
Is a metamorphic rock intrusive or extrusive?
It is neither. Intrusive and extrusive are terms used to describe igneous rock.
What are the most common intrusive and extrusive rocks?
Some common intrusive rocks include granite, diorite, and gabbro, while common extrusive rocks include basalt, andesite, and rhyolite. Intrusive rocks form beneath the Earth's surface from slowly cooling magma, while extrusive rocks form from rapidly cooling lava on the Earth's surface.
