WebMineral crystals that form when magma cools slowly are larger than crystals that form when lava cools rapidly. Minerals form when rocks are heated enough that atoms of different elements can move around and join into different molecules. Minerals are deposited from salty water solutions on Earth’s surface and underground. Review Questions WebThe Mohs hardness of a mineral is determined by observing whether its surface is scratched by a substance of known or defined hardness. To give numerical values to this physical property, minerals are ranked along the Mohs scale, which is composed of 10 minerals that have been given arbitrary hardness values.
