What S The Difference Between Granite And Basalt

Basalt is extrusive while granite is intrusive igneous rock.

What s the difference between granite and basalt. Basalt is available in black brown light to dark grey colors whereas obsidian is available in black blue brown green orange red tan yellow colors. Basalt is called mafic while granite is called felsic. It forms from lava flows which extrude onto the surface and cool. Ks3 what is the difference between granite and basalt.

As it turns out most of the ocean floor is basalt and most of the continents are granite. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Basalt is darker and is composed of magnesium and iron whereas granite is lighter and is made up of feldspar and quartz. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air.

Properties of rock is another aspect for basalt vs obsidian. Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. Basalt splits along columnar planes while granite splits along horizontal planes. This difference is due to the difference in their cooling process.

Basalt vs granite summary of basalt vs granite basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust it forms from lava flows which extrude onto the surface and cool its principle minerals include pyroxene feldspar and olivine it is common both on earth and other planetary bodies. The hardness of basalt is 6 and that of obsidian is 5 5 5. 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.

Its principle minerals include pyroxene feldspar and olivine. Appearance of basalt is dull and soft and that of obsidian is shiny. Basalt is mostly found on ocean floors while granite is the crust of earth in all continents. Volcanic in origin it makes up much of the earth s oceanic crust while granite is a group of igneous and plutonic rocks composed primarily of feldspar and quartz usually contains one or more dark minerals which may be mica pyroxene or amphibole granite is.

All rocks of igneous origin consist of magma or molten earth that finds its way up to. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. 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. What is the difference between basalt and granite answers.

As nouns the difference between basalt and granite is that basalt is mineral a hard mafic igneous rock of varied mineral content. Granite is a felsic rock meaning that it has a high silicon content. Summary of basalt vs. It is mostly made out of quartz mica and feldspar.
