Chapter 10: The Hydrologic Cycle
Water: represents ecosystem capital that provides goods and services.
Fundamental to life and a universal solvent
The Hydrologic Cycle
Sources of Water on Earth: saltwater, polar ice caps and glaciers, and accessible freshwater
Hydrology is the branch of environmental science that deals with water properties, its movement, and distribution on earth.
Water is either soaked into the ground by infiltration and percolation
Convection Cells are driven by sunlight and create major weather patterns
Hadley Cells are the cells closest to the equator. Dry air absorbs moisture as it descends and moist air releases moisture as it ascends
Water Management
The worldwide largest uses of water are irrigation (70%), industry (20%), and direct human use (10%).
Surface Water: dam use, dam impacts marine and wildlife
Groundwater faces issues such as pollution, loss of water to surface water, land subsidence and saltwater intrusion near the coast.Land subsidence is due to water from the aquifer
Water usage
People in developing countries use 1 gallon/day/person for all needs. One person in the US uses 100 gallon/day
