Question: Magnetic field reversals (as represented in the figure above) have been occurring roughly every 200,000 years. If you were to observe iron crystals embedded in oceanic geology that were pointing neither northward or southward, based on plate tectonic theory, what would potentially explain this?
Question: Which piece(s) of evidence offer support of plate tectonic theory being driven by the convection current hypothesis rather than the "expanding Earth" hypothesis (Google it)? Explain your thinking.
Question: Suppose that plate tectonics and continental drift is in fact occurring, as explained by the convection current hypothesis, what is likely true with regards to the relative ages of the Atlantic and Pacific oceans? Might you expect there to be a difference in the diversity of Coral Reef and fish species in these two Oceans? Explain.
