Igneous rocks are fashioned from very hot magma that cools below the surface or lava that cools speedily higher than the area.
Very hot water dissolves extra minerals than cold h2o. When the water gets to be saturated (can’t keep anymore) with dissolved substances or cools, the drinking water simply cannot maintain onto the many dissolved minerals, and the minerals begin to crystallize on really hard surfaces. Samples of minerals that kind in this manner consist of gold, pyrite, and galena.

Metamorphic rocks improve sorts on account of heat and stress. Metamorphic rocks are sedimentary or igneous rocks that have been altered by high heat and/or tension. It is this website far from stunning, then, that metamorphic rocks type at convergent and renovate plate boundaries. Metamorphic rocks that type in this manner have typically develop a foliated texture (wavy layers).
