1) What are the relationships between the distribution and orientation of extensional and contractions faults on Mars with respect to the Mars geoid and the presence of Tharsis? 2) What do these relationships allow us to infer about tectonics on Mars and the role of Tharsis? 3) What is relationship between the planet-scale distribution of fault types and the topography for Venus? 4) What are three key differences between faults on Earth vs. Mars and Venus?

1) What are the three types of volcanism on the Earth? What are their heat sources and causes? 2) What are the three planet-scale volcanogenic provinces of Mars? Which one has been active since the early Noachian perhaps up to the present day? 3) Name the different volcanogenic terranes of Venus and their signature volcanogenic landform? Which terranes may correlate to plume activity? Are any of these volcanogenic terranes older or younger than each other? 4) Why are mantle plumes important to the interpretation of heat flow and topography? 5) Why is it difficult to determine the origins of the hemispheric difference of lithosphere and also, Tharsis for Mars? 6) What are the relationships of mantle heatflow to topography for Venus?
