Cooling rock definition
Basalt is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed b… Webrock, in geology, naturally occurring and coherent aggregate of one or more minerals. Such aggregates constitute the basic unit of which the solid Earth is composed and typically form recognizable and mappable volumes. …

The igneous, sedimentary, and metamorphic rocks when melt again, they form magma. Then the process of melting and cooling to igneous rocks, weathering and eroding of the igneous rocks to sedimentary rocks and application of pressure and heat to form metamorphic rocks again is completed. It forms a cycle which is the rock cycle.
