Magnesium is almost always found in compound form in nature, with the most abundant source being ocean water. Normally, magnesium is found as magnesite, which is magnesium carbonate, or dolomite. In seawater, magnesium is the third most abundant mineral behind both sodium and chloride.Continue Reading
Magnesium can also be found in some foods and is an important part of a healthy diet. Most humans do not get the amount of magnesium they need from food. The best natural source of magnesium in the diet is green leafy vegetables.
Outside of diet, magnesium is used in a number of applications. It is often combined with aluminum to make a strong metal alloy. Magnesium is a very light metal, the second lightest alkaline earth metal. The element normally forms ionic compounds, like magnesium hydroxide, which is more commonly known by the name milk of magnesia.
Another common household item that contains magnesium is Epsom salts. These are normally used as bath salts. The compound in the salts is officially called magnesium sulfate hepahydrate. This form of the element was discovered by a farmer in 1618 in Epsom, England. His cows refused to drink the water from a specific mineral well on his property, indicating that there was something abnormal in the water. Epsom salts are still used today to help with minor skin abrasions and irritations.Learn more about Earth Science
Hydrogen does not exist in pure form in nature and instead is produced from a primary energy source, such as fossil fuels, solar, geothermal and wind energy, or extracted from other elements such as oxygen. Hydrogen is found embedded in, or coexisting with, other elements on Earth, in water and in the atmosphere. Hydrogen is quite abundant but is often difficult to extract and separate from surrounding minerals and elements.Full Answer >
The layer on Earth with the most mass in the mantle, which is made up of silicate compounds, iron, silicon, magnesium, oxygen and aluminum. The mantle is a solid mass that generates heat reaching over 1,832 degrees Fahrenheit, which causes it to melt in a way similar to plastic.Full Answer >
Duralumin is a strong, lightweight alloy of aluminium that is comprised of approximately 4 percent copper and small amounts of manganese, magnesium and silicon. This alloy is widely used in aircraft construction because of its strength and light weight.Full Answer >
Liquid matter is one of the states of matter found in nature. At standard conditions for temperature and pressure, liquids can flow and can take on the shape of the container that they are poured into. However, liquids do have a definite volume.Full Answer >
