CMST 2060 : 1st Midterm Review
Document Summary
1st midterm review cut off point is ch 3 slide 58 correct compositional density of the crust: continental 2. 8 g/cm3, oceanic 2. 9 g/cm3, mantle 3. 3 g/cm3 : heavier because it contains more iron. Scientific method: not a rigid method/ there are different ways to approach it. Rocks at bottom of grand canyon are 2 billion years old. Oxygen is most common in crust and silicon is 2nd. Volcanoes form at divergent, convergent, and hot spots. Hot spots are just very hot stops on outer core that heats up the mantle more than normal. *know the type of faults that major places are. Uniformitarianism can explain that what happens today also happened in the past. Gravity (ridge push trench pull) is the driving force behind plate tectonics. Covalent bonding is strongest because they share electrons. *know the hardness chart salt usually evaporates from a solution carbonates are the minerals that react to acid cation: positive anion: negative.
