What Has A Lower Density Basalt Or Granite
Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
What has a lower density basalt or granite. Summary of basalt vs. 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. Now how come the mass of granite is lesser than basalt. It is common both on earth and other planetary bodies.
Some meteorites have low densities 3 0 g cm 3 but such meteorites are rare among meteorites. For example limestone 2 6 g cm 3 or less quartzite 2 7 g cm 3 and granite 2 7 2 8 g cm 3 are all common low density rocks. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. 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. Granites can be predominantly white pink or gray in color depending on their mineralogy the word granite comes from the latin granum a grain in reference to the coarse grained structure of such a completely crystalline rock. The density of basalt one of the most common kinds of terrestrial volcanic rocks can be as high as 3 0 g cm 3. The mass of granite and bas.
In crystalline rocks like granite which have tight interlocking mineral grains porosity is normally quite low less than 1 percent. Strictly speaking granite is an. This range of densities can also be attributed to a rock s porosity the amount of open space between mineral grains. Its principle minerals include pyroxene feldspar and olivine.
It forms from lava flows which extrude onto the surface and cool.
