Problem 1) How does evolution work? Include why evolution is not a random process. Include comparisons to the breeding of domesticated animals for each step in the process (1 bonus point if your comparison uses Dachshunds, also known as "wiener dogs").
Problem 2) Describe the evidence Alfred Wegner used to propose his idea of continental drift. Why do we use the term plate tectonics now instead of continental drift? What is the main driving force for tectonic plate movement?
Problem 3) Describe the early history of atmospheric gases on Earth. Include the original nebular gases, the Earth's ?rst permanent atmosphere, and how it changed from the Hadean Eon to the Archean and Proterozoic Eons.
Problem 4) Why are rocks from the Hadean and Archean Eons so rare? Name and describe the Precambrian rock that indicates that plate tectonics was happening. Name and describe the 2 rocks that provide evidence of the major change that made the Earth's atmosphere similar to today's atmosphere.
