Document Summary
Hydrogen bond- a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. Surface runoff- the precipitation that does not infiltrate the ground or return to the atmosphere by evaporation (including transpiration from plants) Watershed- also called a drainage basin, is the region from which surface water drains into a river, lake, wetland, or other body of water. Reliable runoff- the amount of runoff that we can generally count on as a stable source of water from year to year. Aquifers- porous, water-saturated layers of sand, gravel, or bed-rock through which groundwater flows. Unconfined aquifers- bounded only by the impermeable layer below. Confined aquifers- bounded by both upper and lower layers of impermeable material. **on final exam - areal sea as a natural disaster. Distillation- heating salt water until it evaporates, leaves behind salt in solid form, and condenses as fresh water.
