It is where it lives and feeds, etc.
Process by which the internal structure of a mineral is altered by the addition or removal of elements. Change in phase (mineral type) and composition are due to the action of chemical agents. Chemical weathering is dependent on available surface for reaction temperature and presence of chemically active fluids.
Igneous rocks are formed when the magma from an erupting volcano eventually cools this rock is extrusive- found on the earth's surface.
Should be decontamination because you are removing the pollution that has been dispersed.
