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 many of the common minerals make up 90 percent of the Earth's crust?

    A:

    More than 90 percent of the mineral composition of the Earth's crust is composed of silicate minerals. These silicate minerals differ with each specific compound, as each compound is composed of different elements to form the types of rock that constitute the Earth's crust.

    How do quartz compare to granite?

    A:

    Quartz is a mineral, while granite is a rock made up of minerals. Only one of those minerals is quartz. Pure quartz is silicon dioxide and is hard and transparent, but impurities can give it a range of colors.

  • Q:

    What are the two main groups of minerals?

    A:

    The two main groups of minerals are the silicates, which are formed from oxygen and silicone, and the non-silicates, which are not composed of silicone and oxygen. Silicate minerals are the largest class of minerals, while non-silicate minerals vary greatly with regard to structure and composition.

  • Q:

    What are the two most common silicate minerals?

    A:

    The two most common silicate minerals are orthoclase and plagioclase. Compared to orthoclase, plagioclase is more abundant in the Earth's crust. Plagioclase is more commonly found in igneous and metamorphic rocks while orthoclase is more common in sedimentary rocks and sand due to its capability of withstanding weather changes.
