Unit 5

103. Wells

Def: A shaft in the ground that conns water oil or gas.

Sen: Wells are where some people have to get thier drinking  water from.

Ex1: Deep hole

Ex2: Kitchen sink

 104. Aquifer Depletion

Def: long term water-level declines caused by sustained ground water pumping.

Sen: Its not good that we are having a decrase in our groundwater.

Ex1: Groundwater pumping

Ex2: Long term water level declines

Ex3: Salt water intrusion

105. Salt water intrusion


Def: when salt water gets into fresh water.

Sen: Salt water intrusions are bad and unhealthy because our freshwater bcomes dirty when it is combined with ocean water.

Ex1: Saline water, sea water

Ex2: Fresh water

106. Dams

Def: A barrier designed to hold back water and raise its level.

Sen: A lot of water id helb by dams.

Ex1: The Hoover Dam

Ex2: A beaver

107. Dam Removal

Def: The process of removing dated, and dangerous dams from river systems.

Sen: Dam removal is a very messy and dangerous process.

Ex1: Glines caynon dam removal

Ex2:Elwaha Dam removal

108. Agriculture effects on freshwater

Def: It disturbs all the freshwater systems.

Sen: These are negative effects and can harm our drinking water.

Ex1: Agriculture

Ex2: Freshwater

110. Non-point source pollution

Def: You can see when the pollution’s coming from.

Sen: I see no point source pollution whe I look inside a sewer.

Ex1: A sewer

Ex2: treatmnt plants

111. Point source pollution

Def: You can’t tell where the pollution is coming from

Sen: I can see the pollutiion but i do not know where it is coming from.

Ex1: sewage plants

Ex2: Smokestack factory

112. Primary waste waste treatment

Def: The process of removing suspended solid waste, and reduce its BOD (Biochemical Oxygen Demand).

Sen: This is a cleaning process.

Ex1: secondary waste water treatment

Ex2:Teriary waste water tratment

113. secondary waste water treatment

Def: The process to catch the dissolved organic matter as food.

Sen: This is getting all of the food out of it.

Ex1: Primary watse water treatment

Ex2:Tertiary watse water treatment

114. Tertiary waste water treatment

Def: When the nutrients are suspended.

Sen: This is the step where everything is finally removed and nthig else needs to be taken out.

Ex1: Primary waste water treatment

Ex2: Secondary waste water treatment

115. Sludge

Def: Thick, soft, wet mud.

Sem: when i think of this i think of the red mushy clay that is sometomes outside.

Ex1: clay

Ex2: silt

Ex3: Loam

94. Density

Def: the compactness of a substance.

Sen: density can be calculated using mass and volume.

Ex1: Mass

Ex2: Volume

95. Surfface Currents

Def: Water at the surface that is moved by the winds that bloe over top of it.

Sen: the winds blow about 400 meters about the surface currents.

Ex1: Coriolis effect

Ex:2: wind patterns

96. Upwelling

Def: The rising of seawater

Sen: Upwellings can be dangerous is you are out siming because you can get swalled in by the depth unexpectidly.

Ex1: Magma


97. Coriolis Effect

Def: A mass in a rotating system expirences a force that isperpendicular to the directio of motion.

Sen: The earth can expirence the Coriolis effect.

Ex1: An astroid coming towards earth.

Ex2: a person pusing a ball.

98. Deep ocean current

Def: They aremade by density and temperature.

Sen: These also can be know as the oceans conveyor belt.

Ex1: Circulation

Ex2: currents

99. water cycle

Def: The process in which water circulate between clouds,lakes, oceans, rivers, and the atmosphere.

Sen: Water from a nearby river is evaporated from the sunlight and goes to the clouds to being condesation then the clouds let go causing percipitation anf the rainfall goes back into  a stream or lake that starts the process over.

Ex1: Evaporation


100. Groundwater

Def: Water thats held underground.

Sen: This ater is what a lot of communites drink.

Ex1: Well

Ex2: soil and rocks

101. Surface Water

Def: Water that is collected from the surface of the ground.

Sen: Surface water can be on or above the ground.

Ex1: puddle

Ex2: small lake

102a. Groundwater Cross section

Water Table: Is the top level of Groundwater.

Permeable Layer: It is clay like and does not allow water to pass, but if so very slowly.

Impermable Layer: In this layer substances such as liquid and gases cant pass. but some are permeable t gas and not liquid.

102b. Groundwater Cross Section

Confined Aquifer: It is an aquifer that is below the land surface that holds water.

Unconfined Aquifer: Whe its upper surface is open to the atmosphere.

Pumped well: Pumping and observing the aquifers.

102c. Groundwater Cross Section

Artisian: A well trapping a confined aquifer.

Zone of saturation: A area in a aquifer below the table where all pores are saturated with water.

Zone of aeration: the zone between the surface and the water table with rock and soil.

Cone of depression: Zone aroud a well where aquifer is normally saturated, table dips down to a cone shape.
