Document Summary
What are the four disciplines that make up earth science? geology, oceanology, meteorology, astronomy. What four spheres comprise the earth system? lithosphere,hydrosphere, biosphere, atmosphere. What are the layers of the earth based on composition? crust, mantle, outer core, inner core. What are the layers of the earth based on physical property? lithosphere, asthenosphere, mantle, outer core, inner core. What criteria must be met to consider a substance a mineral? naturally, solid, inorganic, chemical composition, crystalline. # of protons, mass of protons and neutrons. How do ionic bonds differ from covalent bonds? donation of electrons from one atom to another, sharing electrons in outer energy. What is an isotope? variant of an element. How are euhedral crystals different from anhedral crystals? have good geometric form, lack good geometric form. What are polymorphs and why do they exist? variance of minerals that have the same chemical formula but different shapes and properties.
