What Are Examples of Mineral Salts?
Mineral salts are substances extracted from bodies of water and below the Earth's surface. Some examples of mineral salts include sodium, chlorine, calcium, phosphate, magnesium, sulfur, potassium, and phosphorus. Minerals are important to humankind for their use in foods and in ways that the human b
10 Easy to Identify Rocks and Minerals
Rocks and minerals can be easily identified once you know what to look for. There are three different types of rocks: Igneous, Metamorphic and Sedimentary. Minerals must meet several requirements, including being naturally occurring and inorganic solids.
The minerals channel looks at their formation through geological processes. Discover more about minerals with articles and pictures at HowStuffWorks.
