Precipitation Varies Greatly
• In most areas of Nevada and California, potential transpiration and evaporation is in excess of precipitation, which causes a net moisture deficit
Too Little Water
• Causes– Dry climate– Drought - a period in which precipitation is much
lower and evaporation is much higher– Desiccation - drying of soil because of such
activities as deforestation and overgrazing– Water stress - low per capita availability of water
caused by overpopulation
