Document Summary

Eae1011 lecture 9 - earth, atmosphere and environment. Composition of continental rocks versus oceanic rocks. Why they behave and change the way they do What makes up the earth: rocks. "a mineral is a naturally occurring homogeneous solid with a definite (but generally not fixed) chemical composition and an ordered atomic arrangement. It is usually formed by inorganic processes. " (hurlbut and klein, 1977) Important points: 1. naturally occurring, 2. crystalline solid (atomic arrangement, 3. definite chemical composition (variable, 4. characteristic physical properties (e. g. , hardness, cleavage, crystal form, 5. inorganic: devoid of organic chem.
