Deep lesioning,
The rock moves because forces deep inside earth create stress or pressure in the rock when the pressure in the rock builds up enough,the rock breaks or changes shape releasing energy in the form of waves
because the igneous rock comes from below earth's surface
ore deep beneath earth's surface is mined by drilling holes in the earth's crust so that mines can be built for excavation in which the ore is generally mined near but not to close to the base of a dormant volcano as not to activate the volcano.

Deep shaft mining, open-cast mining & adit mining.
A surface current is on the surface and a deep water current is deep beneath the surface.
heat and pressure in the earths crust with little if any chemical change.
Large crystals are formed in igneous rock that forms from slow cooling magma, deep beneath the Earth's surface.
Ores that are near the Earth's surface can be obtained by scraping away the soil, blasting the ore into small pieces, and removing it with heavy equipment and taking it to smelting plants. Ores that are located deep in the Earth must be mined from tunnels in deep rock.
