unit 5

density
a variety of factors affect water density, mre dense water sinks, settiing up convection currents. Density has its own equation. mass, volume
surface currents
The water at the ocean is moved primarily by winds that blow in certain patterns because of the Earth’s spin and the. oceans rivers
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.it accurs right below the cost line.

ocean , lakes

coriolis effect
 is the apparent deflection of moving objects when the motion is described relative to a rotating reference frame.in tornadoes the Coriolis force is negligible, and balance is between pressurethe world, ocean.

 

deep ocean current
 driven by density and temperature gradientsocean and currents
water cycle 
Plants and animals also add  vapor to the air by transpiration. As it rises into the atmosphere, the water vapor condenses to form clouds. Rain and other forms of precipitation return it to the Earth, where it flows into bodies of  and into the ground, beginning the cycle again.oceans ,clouds
gound water
the water beneath the surface of the ground, consisting largely ofsurface water that has seeped down: the source of water in springsand wells.most of your water that we drink comes froms from the ground.rain, precitation
surface water
 is watersurface of the planet such as in a stream, river, lake, wetland, or oceanWhile most drinking water in the United States is withdrawn from groundwater sources, surface water remains a significant rivers, lakes
wells
people in the country use this mostly water, holes for water
aquifer depletion
Groundwater , a term often defined as long-term water-level declines caused by sustained groundwater pumpingMany areas of the United States are experiencing groundwaterwells, safes for water.
salt water intrusion
 is the movement of saline water into freshwater aquifers, which can lead to contamination of drinking water sources and other consequences.

this is bad if it gets in  your drinking watersalt water, fresh water 

dams
we use this to make electisity.electisity, watercontrol.
dam removal
 is the process of removingdams from river systems.this is bad because a lot of sediment get in the water.

rivers, lakes 

agriculture affects on freshwater
The quality of freshwater at any point on the landscape reflects the combined effects of many processes along water pathwayswe affect the freshwater alot by putting all the sediment in it.river lakes
recreational effects on freshwater
Toxic cyanobacteria are increasingly being perceived as a potential health hazard, particularly in waters used for recreationwe dont help this because we make things all around the freshwater sources.lakes rivers, streams
non point source pollution
pollution from industrial and sewage treatment plants, comes from many diffuse souers we dont know where all the pollution is coming from because there are diffent point were it is made.cars, factories
point source pollution
defines point source pollution as “any single identifiable source of pollution from which pollutants are dischargedwe know where this pollution is coming from.

oil spills, swage 

primary waste water treatment
 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.
we use this to keep our water clean not non infection
chimacils, treatemnt plants
secondary waste water treatment
Secondary treatment is a  process for wastewater (or sewage) to achieve a certain degree of effluentwe need this to drink the water we have.bleach, filters
tertiary waste water treatment
wastewater quality before it is reused, recycled or discharged to the environment.  this is the part  that makes us able to drink the waterheat, cleaning 
sludge
thick, soft, wet mud or a similar viscous mixture of liquid and solid components, especially the product of an industrial or refining process. its the bad part of the water cleaning trash, waste
