			# System tracks
			## Draw the base level cycle and give extra attention to the sequence boundary (chapter 1, slide 62).
			## What is the difference of the definition of the sequence boundary between the 'Exxon slug' with three system tracks and the enhanced model with four system tracks?
			# Fluvial systems
			## Picture given. Which surfaces (1-4) can you see? Which system tracks can you see between the surfaces? Which system track is missing and why? How can you distinguish the system track between 2 and 3 from the other two?
			## Do the Carboniferious cyclotherms work according to the river sequence stratigraphy?
			# Grain-size analysis
			## Give three examples of how you can perform grain size analysis. For each example, is there a link with their density or shape?
			## Explain how and why this is important for reservoir geology.
			# Delta's
			## Three types of deltas (river, wave-and tidal dominated) and there link with the spatial distribution of mud and sand.
