Which Describes Granite And Basalt

The tholeiitic and the alkali basalts.

Which describes granite and basalt.

Basalts may be broadly classified on a chemical and petrographic basis into two main groups. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. Granite is a felsic rock meaning that it has a high silicon content. Basalt extrusive igneous volcanic rock that is low in silica content dark in color and comparatively rich in iron and magnesium.

Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. It is common both on earth and other planetary bodies. Learn more about basalt in this article.

Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air. It is mostly made out of quartz mica and feldspar. Which describes granite and basalt. All rocks of igneous origin consist of magma or molten earth that finds its way up to.

Granite is a coarse grained intrusive igneous rock while basalt is a fine grained extrusive igneous rock. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. Learn more about the properties and uses of granite in this article. Granite is a fine grained extrusive igneous rock while basalt is a coarse grained intrusive igneous rock.

The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. It forms from lava flows which extrude onto the surface and cool. As it turns out most of the ocean floor is basalt and most of the continents are granite. Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals.

It wants to be there and heat is the key which unlocks the door. Granite is an igneous plutonic rock which is. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.

Basaltic crust is dark and thin and heavy while granite is light and accumulates.
