Water is less dense than any of the other materials listed.
In order of density from least to highest:
Basalt is more dense than granite as it contains more iron and magnesium. This means that it is likely that the more dense basaltic plate would be forced under the less dense granitic plate.
Basalt is an extrusive, mafic igneous rock, which means that it solidifies from lava at or near the surface, and is composed partly of iron and magnesium minerals. Granite is an intrusive felsic igneous rock, meaning that it solidifies from magma below the surface, and is relatively high in minerals containing silicon and aluminum. Basalt has a higher specific gravity than granite, and is also darker than granite. Basalt may have visible air pockets, frozen in place when it solidified from lava. Granite will not exhibit this characteristic. Basalt has mineral crystals that are not visible with the naked eye. Granite has visible mineral crystals.
Basalt froms from basaltic lava is heavy, dark-colored, dense lava. Basaltic lava is dark because it contains high amounts of iron and magnesium.
Inner core: Iron and nickel Outer core: Iron, nickel, and oxygen Oceanic crust: Basalt, magnesium, and iron Continental crust: Granite Mantle: Iron, magnesium, and calcium I hope this helped now all I need is a way to remember them all!
iron
Granite is very much less dense than basalt. This is why the continental crust (mostly composed of granite) floats on Oceanic crust (made mostly of basalt). Granite is 70 % silicon. Where basalt is mainly pyroxene.
Basalt is more dense than granite as it contains more iron and magnesium. This means that it is likely that the more dense basaltic plate would be forced under the less dense granitic plate.
Yes
Granite is a felsic (composed of "light" coloured feldspars and silica minerals) intrusive rock. It is formed by the slow cooling and crystallisation of magma below the earths surface in a pluton or batholith. Basalt is the opposite of granite. Basalt is a mafic (dark coloured minerals rich in iron and magnesium)fine grained rock formed from the rapid cooling and crystallisation of lava above ground. Granite: Pale coloured, felsic, intrusive, coarse grained/porphyritic. Basalt: Dark coloured, mafic, extrusive, fine grained.
The core of Earth is mad of iron and nickel. The crust, not the core, is made largely of iron and basalt.

its, IRON
Mafic igneous rocks, like basalt and gabbro.
Oceanic crust is significantly denser.
Lead, iron and water
If it is more dense than water, like gold or iron or mercury or granite, it will sink. If it is less dense than water, like styrofoam, oil or coconuts, it will float. The density of water is very very close to 1 gram per millilitre, or 1 kilogram per litre. Out of interest, ships float becasue they have a lower density than water. Although they are iron, the air within the ships hull makes them less dense than water.
