Document Summary
Physical hydrology: is the study of physical, movement and occurrence of water on and below the surface. This chapter deals with issues of climate hydrology or global hydrology. Atmospheric water: water above the land surface; water is usually water vapor but it can be liquid or solid. Surface water: water stored in ponds, lakes, streams or rivers. Water table: when water rises from the ground from a pit. Saturated zone: zone below the water table. Unsaturated zone: contains soil with both air and water. Soil water: where water is stored from unsaturated zone. Fresh water is important to humans but only 2. 5% is avalible for drinking: 69% is in ice, 30% is from groundwater and 1% is surface water, most underground water is contaminated by salt. Box 1. 1 what if all the polar caps melt: sea levels have been changing due to increase in temperature, sea levels are rising.
