Is Granite More Dense Than Basalt

Granitic rocks are even less dense than basalt.

Is granite more dense than basalt.

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. All rocks of igneous origin consist of magma or molten earth that finds its way up to. You can also know more about granite and basalt reserves. It also has abundant quartz.

Basalt is more common in oceanic crust while granite is more common in continental crust. It forms from lava flows which extrude onto the surface and cool. In geologist s shorthand continental crust is felsic. Granite is a very hard granular crystalline igneous rock which consists mainly of quartz mica and feldspar and is often used as building stone.

In terms of minerals granite has even more feldspar and less amphibole than basalt and almost no pyroxene or olivine. Which would be less dense granite or magma that contains the same minerals as granite. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust. Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks.

Ocean crust is made of basalt and continental crust is mostly granite 3. Summary of basalt vs. Ask students to justify their labels with an explanation that includes the following words. Basalt is more dense than granite true false weegy.

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 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. Gabbro basalt and gabbro have a similar composition just the crystal size differs from different cooling rates same for rhyolite and granite. Ask students to individually label which rock basalt or granite they think is continental crust and which rock is oceanic crust based on their results from the density lab.

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.
