- 2. process of removing dissolved salts from ocean water or from brackish water in aquifers or lakes
- 4. groundwater from the aquifer flows out of the ground onto land or onto lake bottoms through exit points
- 6. precipitation infiltrates the ground and percolates downward through spaces in soil, gravel, and rock until an impenetrable layer of rock or clay stops it
