1. How does plate tectonics influence the presence of economic deposits of copper minerals? Is there a correlation between copper deposits and the tectonic environment?

2. When Wegener first proposed his theory of Continental Drift, he looked at evidence from a variety of sources: sequences of rocks, glacial evidence, fossil evidence, and the structure of mountain ranges on different continents. Which type of evidence do you believe was the most compelling and why?

3. Even though over 95% of all volcanoes are found at or near plate boundaries, all volcanoes are not equal in their behavior and do not have the same types of magma or lava. Why is magma at divergent plate boundaries mafic in composition, whereas magma at convergent plate boundaries is intermediate or felsic in composition?

4. It is natural for a river to flood, which is why the land adjacent to rivers is referred to as the floodplain. In August 2017, Hurricane Harvey dropped between 40 and 60 inches of rain over four days in the greater Houston area, flooding major rivers and bayous, and causing over $125 billion in damages to roadways, homes, bridges, and infrastructure, and killed 68 people. How did urbanization play a role in the effects of this storm on the greater Houston area?
