Which Describes Granite And Basalt

Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.

Which describes granite and basalt. Both granite and basalt are fine grained intrusive igneous rocks. Which describes granite and basalt. 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.

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. As it turns out most of the ocean floor is basalt and most of the continents are granite. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air. The tholeiitic and the alkali basalts.

Basaltic crust is dark and thin and heavy while granite is light and accumulates. 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. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals.

It forms from lava flows which extrude onto the surface and cool. Granite is an igneous plutonic rock which is. It most commonly forms as an extrusive rock such as a lava flow but can also form in small intrusive bodies such as an igneous dike or a thin sill it has a composition similar to gabbro the difference between basalt and gabbro is that basalt is a fine grained rock while. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite.

It wants to be there and heat is the key which unlocks the door. Basalt extrusive igneous volcanic rock that is low in silica content dark in color and comparatively rich in iron and magnesium. Granite is a felsic rock meaning that it has a high silicon content. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth.

It is mostly made out of quartz mica and feldspar.
