Rare earth minerals Hard commodities are non-renewable, meaning there is only a finite amount of each of these products. Having a finite amount of something creates scarcity, which makes pricing these commodities different from soft commodities. These materials are also durable –- They can generall...
Soils are the primary provider of nutrients and water for much of the plant life on earth. There are 18 elements considered essential for plant growth, most of which are made available to plants through root uptake from soils (Brady & Weil 2007). Soils retain nutrients by several mechanisms....
"Polished cabochons of cinnabar are sometimes seen in jewelry." Now That's Interesting Cinnabar is one of the few minerals that is sectile, meaning you can cut it into thin pieces with a knife. Gold is another sectile mineral, while pyrite, aka "fool's gold," is not and will crumble...
