Describe the typical rates of relative motion between plates.

Discuss the plate-tectonic evolution of South America over the last $140$ million years.

Sketch and label the characteristics of a continental rift (i.e., a divergent boundary within a continent).

Discuss how plate tectonics can explain similar continental outlines and geology on opposite sides of an ocean.

Determine whether the pinacol rearrangement, shown in the (a) (R)-2-Ethoxy-1,1-dimethylcyclobutane (b) Cyclopropyl isopropyl ether

When 3-methyl-1-butene reacts with HBr, two alkyl halides are formed: 2-bromo-3-methylbutane and 2-bromo-2-methylbutane. Propose a mechanism that explains the formation of these two products.

Sketch and explain the driving forces of plate tectonics.

Sketch and describe the present plate-tectonic setting of South America, and explain the main features on the continent and adjacent seafloor.
