Convection in the earth"s mantle and seafloor spreading. Testing the plate tectonic hypothesis with fossil plankton. Passive boundaries, active boundaries, and what geologic features form at each. History of atomic theory: thought experiments, whole number ratios, brownian motion. Be familiar with the physical properties of minerals and how geologists identify minerals in the field. Plutons: dikes and volcanic pipes, sills and laccoliths, batholiths, xenoliths. Be able to read the rock and mineral chart of slide #25 (you will have a copy of this chart for the exam) Formation of morb and the conversion of morb to granite.
