Flood: Farming and Erosion
Farmers and rivers have a close, though not always friendly, relationship with one another. Rivers can create prized farmland, but they also flood fields and the communities built alongside them. What's more, farming practices may contribute to an increase in the magnitude and intensity of river flooding.

Cave Formations: Biogeochemical Cycles
The most common process by which limestone caves form involves carbonic acid — or weakly acidic groundwater — as the primary agent. When carbonic acid contacts limestone, it dissolves minerals in the rock. If enough water to saturate the rock is present over a long time period, cavities and entire underground cave networks can form. Recently, a radical new theory has been proposed that identifies another cave-forming agent: sulfuric acid. This video segment adapted from NOVA identifies the m
