96.                           upwelling
Upwelling is an oceanographic phenomenon that involves wind-driven motion of dense, cooler, and usually nutrient-rich water towards the ocean surface, replacing the warmer, usually nutrient-depleted surface water.
Upwelling occurs in the open ocean and along coastlines


97.                             Coriolis Effect
n physics, the Coriolis effect is the apparent deflection of moving objects when the motion is described relative to a rotating reference frame.___________________________________________________ The Coriolis effect is caused by the rotation of the Earth and the inertia of the mass experiencing the effect___________________________________________________1.earth’s roation

99.                            water cycle
the cycle of processes by which water circulates between the earth’s oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration.

______________________________________________30 percent of freshwater is in the ground._________________________________________________________1.water2. snow

100.                      ground water
____________________________________________________________________It is stored in and moves slowly through geologic formations of soil, sand and rocks called aquifers._____________________________________________________1.rock2.minerals
101.                          surface water
 is water on the  of the planet such as in a stream, river, lake, wetland, or ocean. It can be contrasted with groundwater and atmospheric . Non-saline surface water is replenished by precipitation and by recruitment from ground-water.

___________________________________________________surface and ground water are two separate entities, so they must be regarded as such._________________________________________________________2.rivers

102.                   Ground Cross Section
water table:the level below which the ground is saturated with water.layer of porous material (rock or unconsolidated sediment); in an aquifer, the layer through which water freely passes as it moves through the subsurface.impermeable layer: ofimpermeable substances like clay or dense rock. When tapped by a well, water in confined aquifers is forced up, sometimes above the land surface.

Artesian well: A well tapping a confined (or artesian) aquifer.confined aquifer:

Confined aquifers are aquifers that are overlain by a low permeability, confining layer, often made up of clay. The confining layer may offer some protection from surface contamination.
unconfined aquifer:An unconfined aquifer, is an aquifer which has the water table as its upper boundary. Unconfined aquifers occur near the ground surface.

pumpedwell:anenclosure in the  of a ship’s  that protects the  
artisian well: well in which water is under pressure; especially : one in which the water flows to the surface naturally. 
zone of saturation:The phreatic zone, is the area in an aquifer, below the water table, in which relatively all pores and fractures are saturatedwith water. The phreatic zone defines the lower edge of the vadose zone zone of aeration:Zone of Aeration (vadose zone or unsaturated zone) the zonecone of depression:cone of depression occurs in an aquifer when groundwater is pumped from a well. In an unconfined aquifer (water table), this is an actualdepression of the water levels.

103.                              *wells
pros:well water is freeIt’s not chlorinated or fluoridatedthere are no monthly bills to deal withsaves lots of money cons:well water may not be as pure it may pose risks that could cause illness if not addressed disease-causing bacteria can enter your well water supply through damaged casings or through the walls of a dug or shallow well. Chemicals like arsenic and radon can also contaminate the water from the surrounding rocks, and old pipes can transfer lead into the water.;
104.                          *Aquifer Depletion
pros:good drinking water and beneficial for irrigationit is use all year; it can be found anywhere it can be renewable as long as it is not contaminated or over used and it is cost effective compared to most surface waters water is not lost because of evaporation;cons:cost is greater  there is impurity from deeper wellwater low
105.                    *Salt Water Intrusion
pros:only occurs naturally to some degree in most coastal aquifers, owing to the hydraulic connection between groundwater and seawater.cons:sea-level rise will increase inundation and salinity along coastal regions worldwide.

As water level increases, saltwater encroaches farther inland in many coastal areas.

106.                             *Dams
Pros:Recreation (lake)Flood control downstreamIrrigation potential from water storageHydroelectric Power generation capabilityEvening out of flow during the year   Cons:Flooding upstream (buried by water)Loss of sediment below stream (delta starvation)Silting of lakePotential dam failureEvening out of flow during the year (prevents sediment renewal on floodplain) 
107.                          *Dam removal
pros:rehabilitation of a healthy aquatic ecosystem that will provide desired ecosystem services. Transporting formerly impounded sediment downstream allowed the formation of important fish spawning habitat including pool and riffle areas and gravel and cobblestone streambed reaches, ultimately increasing the biotic diversity within the river. Dammed rivers result in a more lake-like environment in which there is warmer water, and free-flowing rivers are usually colder environments.

Because a free-flowing river contains more cold-water species like salmon, trout, and sturgeon, dam removal promotes economically desirable fisheries.Dam removal may benefit the terrestrial environment as well. ;cons:Dam removal can be very expensive.

 cause supersaturation within the river. Depending on the material used to construct the dam and artificial material built up behind the dam, removal may cause large amounts of lethal toxins to be released downstream. Further, removing dams that provide electric power results in the loss of energy generation. This loss may be filled by creating more power from non-clean energy sources like coal. 


          *agriculture effects on freshwater

Pros:These swamps helped buffer the the effects of hurricanes, cyclones, and tsunamis; it is believed that the loss of coastal wetlands along the Mississippi Delta contributed to the immense devastation from Hurricane Katrina. Other agricultural areas were also affectedCons:Many of the concerns surrounding fish farming arise from the crowding together of thousands of fish in their artificial environment. Waste products, including feces, uneaten food, and dead fish, are flushed (often untreated) into the surrounding waters where they add to the contamination of the water supply.
109.           *recreational effects on freshwater
pros:creates a reservoir ,or a place where water is stored and prevents the water from continuing downstream.

There are several benefits to damming waterways, such as flood prevention and providing a source of water for human consumption and agricultural irrigation.;cons:creating structures that prevent the natural flow of water can cause it to build up and release all at once in a dangerous flood

110.                 non-point source pollution
NPS pollution is caused by rainfall or snowmelt moving over and through the ground.

As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters.___________________________________________________As the runoff moves, it picks up and carries away natural and human-made pollutants, finally depositing them into lakes, rivers, wetlands, coastal waters and ground waters._____________________________________________________1.water2.food

111.                   point source pollution
Point source pollutionpollution that comes from a single, discrete place, typically a pipe. The Clean Water Act specifically defines a “point source” in section 502(14) of the Act.Water pollution coming from a single point, such as a sewage-outflow pipe._________________________________________________________1. water2.food

___________________________________________________Wastewater treatment is done in a series of steps that can have increasing effectiveness and complexity depending on the resources available. ___________________________________________________1.


113.              secondary waste water treatment
 is a treatment process for wastewater (or sewage) to achieve a certain degree of effluent quality by using a sewage treatment plant with physical phase separation to remove settleable solids and a biological process to remove dissolved and suspended organic compounds.

___________________________________________________Secondary treatment is the portion of a sewage treatment sequence removing dissolved and colloidal compounds measured as biochemical oxygen demand (BOD)_________________________________________________________1.


114.                     tertiary waste water tretment
Tertiary treatment is the final cleaning process that improves quality before it is reused, recycled or discharged to the environment. The treatment removes remaining inorganic compounds, and substances, such as the nitrogen and phosphorus.Tertiary treatment is the final cleaning process that improves wastewater quality before it is reused, recycled or discharged to the environment.________________________________________________________1.treatment2. waterr
