## Other Practice Questions on Terrestrial Planets

1. You must know the following terms: Caloris Basin, Weird terrain, Antipodal, scarps and know what planet contains these objects. Be able to identify the images of scarps, as well as the Caloris Basin on this website: Caloric Basin
2. According to Wikipedia, is there wind on Venus? On the test you will be asked to describe two (entirely different) things you learned about wind at the surface of Venus. (You might want to describe Hadley cells, since we need them for the gas (giant) planets).
3. Venus has two 'continents' Aprodite Terra and Ishtar Terra. You don't need to know their names, but you do need to what their names have in common.
4. What is it about Venus that causes the continents to be so small and relatively immoble? (Why is there little or no continental drift?)
5. Understand the two types of volcanoes on Earth. Again, you don't need the names, just describe them.
6. This permalink to Volcanology of Venus makes a specific claim regarding whether it is known that active volcanoes exist on Venus today. What does Wikipedia have to say?
