Basic to teaching Earth science. In this program, we find out how a petrologist looks at them, especially the crystalline state that characterizes minerals. The best way to demonstrate that minerals are crystalline is to show that they diffract X-rays. The variety of diffraction patterns produced is extremely useful in distinguishing different minerals from each other. A demonstration of diffraction and the theory behind it will be presented with practical applications.
