I would learn my interaction with the rock cycle and interaction with river processes as one of them is bound to come up. Earthquakes maybe because of the earthquake activity in 2015 and predicting them and preventing damage caused. The feature of deposition is likely but i would know both erosion and deposition.
For the economic section if your doing it know Globalization in a developing economy (hasnt come up for a while) and eu policies. Mncs are on every year too. For regional contrasting manufacturing activity in the west and gda maybe.
