4.5: Formation of Minerals
Most of the minerals of Earth's crust formed through the cooling of molten rock (magma or lava). Molten rock is very hot, typically on the order of 1000 (^{circ})C (1800 (^{circ})F) or more. Heat is energy and temperature is a measure of that energy. Heat causes atoms to vibrate and temperature measures the intensity of the vibration.

2.1: Minerals
Minerals are made up of atoms, and all atoms are made up of three main sub-atomic particles known as protons, neutrons and electrons. As summarized in Table 2.1.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged. The negative charge of one electron balances the positive charge of one proton.

1 Introduction – Mineralogy
All minerals, like all materials, consist of one or more elements, the building blocks of all matter. Some minerals, diamond for example, contain a single element (carbon). Others contain many elements. Some minerals have compositions that vary little in nature. Quartz for example is always close to silicon and oxygen in the atomic ratio 1:2.

2.4: Mineral Basics
Minerals commonly grow in layers that accrete onto the surface of earlier-formed parts of the mineral. If a mineral has a variable chemical composition that changes as the chemistry, pressure, and temperature of its environment changes, the layers of mineral growth can be analyzed to track the changing conditions in which the mineral grew.

4.4: Mineral Formation
The amount of mineral formed is the same as the amount dissolved in the water. Seawater is salty enough for minerals to precipitate as solids. Some lakes, such as Mono Lake in California, or Utah's Great Salt Lake, can also precipitate salts. When the water in glass A evaporates, the dissolved mineral particles are left behind.
