Water Flashcards
parts of the water cycle
evaporation, transpiration, runoff, condensation, precipitation, infiltration
aquifer
any water-bearing layer in the ground
cone of depression
lowering of the water table around a pumping well
salt water intrusion
near the coast, over pumping of groundwater causes saltwater to move into aquifer
ENSO
El Niño Southern Oscillation, see-sawing of air pressure over the south pacific
during an El Niño year
trade winds weaken and warm water sloshes back to South America
during a non El Niño year
easterly trade winds and ocean currents pool warm water in the western Pacific, allowing upwelling of nutrient rich water off the west coast of South America
effects of El Niño
upwelling decreases disrupting food chains, N. U.S. has mild winters, S.W. U.S. has increased rainfall, less Atlantic hurricanes
percent of water on earth by type
97.5% seawater, 2.5% freshwater
ways to conserve water
agriculture = drip/trickle irrigation; industry = recycling; home = use gray water, repair leaks, low flow fixtures
transpiration
process where water is absorbed by plant roots, moves up through plants, passes through pores (stomata) in leaves or other parts, evaporates into atmosphere as water vapor
