APES: The water cycle
Terms in this set (58)
water with very little salt
the continuous cycle of the transfer of water through an ecosystem, which involves evaporation, transpiration, condensation, and precipitation
the process by which water changes from liquid form to an atmospheric gas
the loss of water as it moves from the soil through green plants and exits through their leaf pores
the process of changing from a gaseous to a liquid or solid state
any form of water that falls from clouds and reaches Earth's surface
amount of water available to meet demands
The degree of purity of water, determined by measuring the substance in water, besides water molecules.
water that contains dissolved salts and other minerals
Saltwater mixed with freshwater
Water with high mineral content.
water that is relatively free of minerals
water that contains high levels of unwanted substances that may be harmful to living things
water that has had pollutants removed or is rendered harmless
Water that results from a storm; can cause flooding and contamination of sewers.
water vapors in the gaseous state
the amount of water vapor in the air
the amount of water vapor as a percentage of what the air can hold at a particular temperature
microscopic liquid or solid particles orginating from land and water surfaces
When water evaporates, particles such as dissolved salts & other solids remain behind. When the water vapor condenses again, it is purified.
the cooling of air as a result of expansion of rising air
air descends and is compressed by higher air pressure in the lower atmosphere
without heat being involved
the upward movement of warm air and the downward movement of cool air
dry region downward of a mountain range
a system of vertical and horizontal air circulation predominating in tropical and subtropical regions and creating major weather patterns.
the process of water soaking into the soil
amount of precipitation that soaks into the ground compared to the amount that runs off.
The land area that supplies water to a river system.
All ponds, lakes, streams, rivers, and other waters on the surface of Earth.
is water held by surface tension to soil particles, but it can move through pores in response to moisture gradients (from areas of high moisture to areas of low moisture). Plants are able to overcome the surface tensions and take-up this water, thus it is available water to plants.
The evaporation of water from soil plus the transpiration of water from plants.
Passage of a liquid through the spaces of a porous material such as soil.
water in a soil that percolates through to the water table.
water found beneath Earth's surface in aquifers
underground places where water collects
area where water enters the aquifer
pass gradually or leak through or as if through small openings
a natural flow of ground water
water evaporates and returns by precipitation
surface runoff loop
water becomes part of surface water system
water percolates and moves through to eventually join ground water.
Solid and liquid materials in the air that are of natural or anthropogenic origin, causes smog and haze.
replenished by percolation of precipitation water
when recharge rate is centuries or more
The gradual sinking of land. The condition may result from the removal of groundwater or oil, which is frequently instrumental in supporting the overlying rock and soil.
a depression produced in a region where soluble rock has been removed by groundwater
all of the wastewater that drains from washing machines, sinks, dishwashers, tubs or showers and can be reused for non-sanitary purposes
a method of landscaping that uses plants that are well adapted to the local area and are drought resistant.
a bay or drowned valley where a river empties into the sea
surge flow method
computers control the periodic release of water
drip irrigation method
a proccess by which pipes placed near plant roots drip only as much water as the plants need.
A process for purifying water in which the water is forced under very high pressure through a membrane that is fine enough to filter out ions and molecules in solution; it is used by small desalination plants to filter salt from seawater. Also called reverse osmosis.
