Well, for such a question I'd probably start with a granite landscape. That would allow you to say all sorts of stuff about reservoirs (Impermeable rock), mining activities (China Clay, Granite, road surfacing), tourism (People going to look at tors and stuff) and Farming (Low intensity, probably sheep farming because boggy ground because impermeable surfaces). Then for chalk and clay economic uses include Farming (High intensity, good soils), water storage and pumping (in the aquifer) and quarrying (?). That's all I can remember of the topic and it was a year ago... But if you have any questions, I'm here to help (will take payment in hugs).
