Density of Minerals and Rocks
... The importance of density lies in the fact that when there are two objects with different densities and phases, the more density will sink. The fact that you are here at the bottom of the ocean of air is one trivial example. Also, when two fluids (liquids or gases) have different densities, the less ...

Basalt

Basalt (pronounced /bəˈsɔːlt/, /ˈbæsɒlt/, /ˈbæsɔːlt/, or /ˈbeɪsɔːlt/)is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Flood basalt describes the formation in a series of lava basalt flows.
