Q:

What are two ways that minerals form?

A:

Quick Answer

The two main methods of mineral formation are cooling and evaporation. The cooling process occurs when magmas and lavas cool and crystallize into minerals. Minerals formed through evaporation are the result of electrically charged atoms, known as ions, linking together to form crystals.

Full Answer

Most of the Earth's minerals are created through the cooling process. Cooling is also responsible for the formation of most of the rocks and gemstones in the Earth's crust. A third method of mineral formation is known as crystallographic transformation. This is a process in which minerals change into new minerals as a result of chemical instability.

  • Q:

    How are rocks different from minerals?

    A:

    Rocks are different from minerals in that minerals are single crystalline accumulations of one or more elements, while rocks are solid accumulations of one or more minerals. Rock can either refer to a particular, detached object or, in a general sense, as a synonym for stone, generally referring to a portion of the substance. Individual minerals can be obvious in rocks, as with granite, or microscopic, as with many basalts.

  • Q:

    How are minerals formed?

    A:

    Minerals are formed under a variety of conditions, including when molten materials cool, when liquids evaporate or cool and under high temperatures and pressures. Minerals are found in the earth's crust and mantle, and many were created when feldspar and quartz reacted with other materials during the formation of the planet.

  • Q:

    Where do minerals come from?

    A:

    Minerals come from the Earth’s crust, and they are found in various places throughout the world. Geological processes, such as metamorphic, sedimentary and igneous processes, are responsible for the concentration of minerals. Mineral deposits form into different shapes and sizes depending on the location and process of concentration.
