I. Hydrology: the study of the water cycle. Draw the water cycle: Label transpiration, precipitation, condensation, evaporation, runoff, and ground water. A. Runoff moves water across the surface. Amount depends on: 1. shape of land (steepness) 2. amount of rainfall 3. amount of pavement 4. amount of plants (they soak up water) B. Watershed- area drained by a river and its tributaries (small streams that flow into larger ones). C. Ground Water- soaks into the ground 1. Zone of aeration – depth where pores of 2. Zone of saturation – depth at which groundwater completely fills all pores of rock & soil with water.

Unformatted text preview: of saturation. Draw & label these layers using diagram on p. 241. Soil & rock holds water: A. Porosity – ratio of the volume of air space in the rock to the total volume of the rock. Large grained rocks & soil have greater porosity than small grained rocks or soil. B. Permeability – ability of rock to allow water to pass through. (A porous rock may not be permeable. It depends on the extent to which the pores are connected.) 1. Aquifer – a permeable rock layer that transports water underground. 2. Wells must be drilled into an aquifer. 3. Artesian well – pressure pushes water up out of the ground without a pump. Draw the aquifer pictured on p. 243....
