Basalt Or Granite More Dense

Now how come the mass of granite is lesser than basalt.

Basalt or granite more dense. Since gabbro and basalt are made of the same minerals their densities are similar. Collect density of the continental crust and oceanic crust handout and use the handout as an evaluation of students understanding. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Gabbro s density ranges from 2 7 3 3 g cm 3.

Basalt is denser than granite because basalt is a an oceanic type of rock so it has had more pressure from the ocean making it denser than granite because granite is a continental type of rock. I m confused by some of what you say as it seems to conflict what i ve learned in geology courses namely that gabbro is the large grained slow cooled equivalent of basalt both of them dark colored and high in iron and magnesium based minerals while granite is the slow cooled large granied equivalent of rhyolite both of them fairly light in color and high in feldspar and quartz. Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks. 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.

Less dense more dense water basalt granite oceanic crust and continental crust. 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. This means that it is likely that the more dense basaltic plate would be forced under the less dense granitic plate. Gabbro basalt and gabbro have a similar composition just the crystal size differs from different cooling rates same for rhyolite and granite.

The mass of granite and bas. And not all granites basalts and gabbros contain exactly the same minerals. Rock density is very sensitive to the minerals that compose a particular rock type. Basalt is a common extrusive igneous rock formed by the rapid cooling of basaltic lava exposed at or very near the surface of earth.

Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone. Density is a mass per volume let say if we have same ammount of volume granite and basalt what make granite less dense is because it has less mass than basalt. Evaluate 5 minutes a rock s density determines its location in the earth s layers. Basalt is more dense than granite true false weegy.
