Tomorrow is the test on Ground and Surface Water!!! Today you received a study guide and had the entire class period to work on it.  In addition to the study guide remember that these are the things the classes decided you needed to know:  

Vocab: surface water, channel, tributary, watershed, divide gradient, flow, stream load, precipitation, runoff, aquifer, porosity, permeability, recharge, discharge, water table, infiltration.

Skills:  Accurately label a diagram showing the vocab above,
Determine and explain how gradient can affect flow and stream load
Determine which Earth has more of:  Fresh or salt water, ground or surface water
List and/or explain uses of ground and surface water (page 38)
Explain how porosity and permeability affect infiltration
Explain how the loss of water can have an effect on societies (Think Syria, but you can also refer to page 39).
