What is less dense water basalt iron or granite?
Water is less dense than any of the other materials listed.
In order of density from least to highest:
- Water (least dense)
- Iron (most dense)
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 general how does the density of a light colored igneous rock differ from that of s dark colored igneous rock?
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…
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…
They are both formed by the crystallisation of magma. Basalt is formed when basic (i.e. high iron and magnesium, low silica) magma freezes above ground as a lava flow, resulting in the very fine crystals. Granite is the crystallised form of more felsic (silica-rich) magma, which has crystallised at depth within the Earth, resulting in a large crystal size.
No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks. The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.
Metal is more dense than rock. Early in the history of the Earth, the whole planet was very hot and everything was liquid, and the heavier liquid components of the planet were able to sink through the lighter liquids which floated to the top. We think of rock such as granite as being very dense, but everything is relative. Granite is less dense than iron, and it floats on top.
