What Has A Lower Density Basalt Or Granite

Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.

What has a lower density basalt or granite.

This range of densities can also be attributed to a rock s porosity the amount of open space between mineral grains. Granite ˈ ɡ r æ n ɪ t is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Now how come the mass of granite is lesser than basalt. It is common both on earth and other planetary bodies.

All rocks of igneous origin consist of magma or molten earth that finds its way up to. Strictly speaking granite is an. 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. It forms from lava flows which extrude onto the surface and cool.

Porosity and density. Its principle minerals include pyroxene feldspar and olivine. This is measured either as a decimal between 0 and 1 or as a percentage. Some meteorites have low densities 3 0 g cm 3 but such meteorites are rare among meteorites.

In crystalline rocks like granite which have tight interlocking mineral grains porosity is normally quite low less than 1 percent. 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. Density is a mass per volume let say if we have same ammount of volume granite and basalt what make granite less dense is because it has less mass than basalt.

The mass of granite and bas.
