Which describes granite and basalt.

Basalts may be broadly classified on a chemical and petrographic basis into two main groups. 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. Granite is a felsic rock meaning that it has a high silicon content.

It is common both on earth and other planetary bodies. Its principle minerals include pyroxene feldspar and olivine. It is the most common plutonic rock of the earth s crust forming by the cooling of magma silicate melt at depth. As it turns out most of the ocean floor is basalt and most of the continents are granite.

The tholeiitic and the alkali basalts. Granite coarse or medium grained intrusive igneous rock that is rich in quartz and feldspar. 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. The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core.

Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air. Both granite and basalt are fine grained intrusive igneous rocks. It forms from lava flows which extrude onto the surface and cool. It is mostly made out of quartz mica and feldspar.

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 is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Basalt extrusive igneous volcanic rock that is low in silica content dark in color and comparatively rich in iron and magnesium.

All rocks of igneous origin consist of magma or molten earth that finds its way up to. Basaltic crust is dark and thin and heavy while granite is light and accumulates. 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.
