Which Describes Granite And Basalt

Basalt is a dark colored fine grained igneous rock composed mainly of plagioclase and pyroxene minerals.

Which describes granite and basalt.

Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air. Its principle minerals include pyroxene feldspar and olivine. The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. Basaltic crust is dark and thin and heavy while granite is light and accumulates.

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. It forms from lava flows which extrude onto the surface and cool. It wants to be there and heat is the key which unlocks the door.

It is common both on earth and other planetary bodies. Both granite and basalt are fine grained intrusive igneous rocks. 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.

Granite is a coarse grained intrusive igneous rock while basalt is a fine grained extrusive igneous rock. Granite is a felsic rock meaning that it has a high silicon content. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. 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.

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. Which describes granite and basalt. Granite is an igneous plutonic rock which is. 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.
