Basalt And Granite Density

Gabbro s density ranges from 2 7 3 3 g cm 3.

Basalt and granite density.

And not all granites basalts and gabbros contain exactly the same minerals. Granite is an igneous plutonic rock which is. The trick is to heat the basalt back up again so it can melt and give the iron another shot at the core. Basalts may be broadly classified on a chemical and petrographic basis into two main groups.

The tholeiitic and the alkali basalts. Link mountain formation in lesson 6 10 is dependent upon the density of the crust. Granite is a felsic rock meaning that it has a high silicon content. Time 120 minutes lesson can be divided into two sessions maintaining the order of the lesson materials per group groups of 4 5.

Learn more about basalt in this article. It is common both on earth and other planetary bodies. 6 11 density of granite and basalt lesson concept density of basalt and granite affect the formation of landmasses on earth. It is mostly made out of quartz mica and feldspar.

Its principle minerals include pyroxene feldspar and olivine. Basalt extrusive igneous volcanic rock that is low in silica content dark in color and comparatively rich in iron and magnesium. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Its high iron content gives it magnetic properties and it may show signs of rust when exposed to air.

Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks. All rocks of igneous origin consist of magma or molten earth that finds its way up to. It wants to be there and heat is the key which unlocks the door. Since gabbro and basalt are made of the same minerals their densities are similar.

Basaltic crust is dark and thin and heavy while granite is light and accumulates. 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. And if you know your igneous petrology you will see that the more mafic rich in magnesium and iron a rock is the greater its density.

Basalt as a mafic rock contains more calcium oxide manganese oxide and iron compounds than granite. 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.
