The chemicals in a mineral are just like the ingredients in a cake. There has to be exactly the right amount of each chemical for the mineral to form properly. You cannot leave out any of their 'ingredients'. Cakes are like minerals in this way. Do cakes have an ordered atomic arrangement? No. However well you mix the ingredients in a fruit cake, some slices will always contain more fruit than

The study of rocks and minerals introduces students to the science of geology. By examining different types of rocks and minerals found in the earth's crust, students will learn that the unique characteristics and properties of rocks and minerals are a result of how they were formed. Such properties determine possible uses. It is important that students become aware of how human uses of rocks

A mineral deposit is a natural concentration of minerals in the earth's crust. The degree of concentration is called the "grade" of a mineral deposit. An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine. Essentially this means that per tonne of rock containing the desired minerals, the costs of removing the minerals from the rock
