It is common both on earth and other planetary bodies.
Is basalt or granite denser.
All rocks of igneous origin consist of magma or molten earth that finds its way up to.
Granite is an igneous plutonic rock which is.
Compared to the familiar granite of the continents basalt ba salt is darker denser and finer grained.
Basaltic crust is dark and thin and heavy while granite is light and accumulates into continent sized rafts which bob about like corks in this sea of basalt when a continent runs into a piece of seafloor it s much like a mac truck.
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.
It s dark and dense because it s richer in the dark heavy minerals bearing magnesium and iron that is more mafic and poorer in silicon and aluminum bearing minerals.
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.
Since gabbro and basalt are made of the same minerals their densities are similar.
When we have to compare granite vs basalt the texture color and appearance plays an important role in determining the type of rock.
As you can see rocks of the same type can have a range of densities.
Sedimentary rocks and granite which are rich in quartz and feldspar tend to be less dense than volcanic rocks.
And if you know your igneouspetrology you will see that the more mafic rich in magnesium and iron a rock is the greater its density.
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.
Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
Gabbro s density ranges from 2 7 3 3 g cm 3.
Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.
Granite is available in black grey orange pink white colors whereas basalt is available in black brown light to dark grey.
The day after the lab is a good time to question the students about the significance of rock densities.
