For example, in China, Britain, and the northeast of the United States, in areas where salt mining and energy storage are needed, most of the formations are bedded salt rocks or even thinly bedded salt rock.

Mohs Hardness Scale

The Mohs hardness scale is a qualitative test that measures the hardness of a mineral by its ability to visibly scratch softer minerals. The scale isn't perfect, but it's a great tool for quick identification of rocks in the field. Here a look at the scale, how ordinary minerals and objects rank, and how to perform the Mohs test.

Treating Hard Water: How Many Grains Should I Get On My …

As hard water passes through the tank, the positively charged calcium and magnesium ions are attracted to a negatively charged bed of resin beads. Because the positive charge of calcium and magnesium ions is stronger than the positive charge of sodium and potassium, the resin exchanges the hard water minerals for the salt and traps them.

Igneous Rocks

Igneous rocks are "fire-born," meaning that they are formed from the cooling and solidification of molten (melted) rock. The word igneous derives from ignis, the Latin word for "fire." Molten rock material is known as magma until it is erupted onto the surface when it then is termed lava.
