#94 Density
-A characteristic property of a substance like water.

-The density of a substance is the relationship between the mass of the substance.

– Mass
– Volume

#95 Surface Currents
– When winds are able to move the top 400 meters of the ocean.

– Surface ocean currents form large circular patterns called gyres.

– Gyres
– Coriolis Effect

#96 Upwelling
– 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 underneath the coastline.

– Wind
– Ocean Surface

#97 Coriolis Effect
– The apparent deflection of moving objects when the motion is described relative to a rotating reference frame.

– The Coriolis effect makes storms swirl clockwise in the Southern hemisphere and counterclockwise in the Northern Hemisphere.

– Coriolis Force
– Wind

#98 Deep Ocean Current
– A current deep in the ocean.

– Deep ocean currents are driven by density and temperature gradients.

– Upwelling
– Oceans conveyor belt

#99 Water Cycle
– The cycle of processes by which water circulates between the earth’s oceans, atmosphere, and land.

– The water cycle include evaporation, condensation, and precipitation.

– Condensation
– Precipitation

#100 Ground Water
– The water present beneath Earth’s surface in soil pore spaces and in the fractures of rock formations.

– Groundwater is water held underground in the soil or in pores and crevices in rock.

– Water
– Surface Water

#101 Surface Water
– Water on the surface of the planet such as in a stream, river, lake, wetland, or ocean.

– Surface water can be contrasted with groundwater and atmospheric water.

– Groundwater
– Water

#102 Groundwater labeling
– The water beneath the surface of the ground, consisting largely of surface water that has seeped down.

– Groundwater labeling is the source of water in springs and wells.

– Groundwater
– Surface Water

#103 Wells
– A shaft sunk into the ground to obtain water, oil, or gas.

– A well can be used to get fresh water out of the ground.

– Shaft
– Groundwater

#104 Aquifer Depletion
– Long-term water-level declines caused by sustained groundwater pumping.

– Aquifer depletion is a key issue associated with groundwater use.

– Groundwater depletion
– Aquifer

#105 Salt Water Intrusion
– The movement of saline water into freshwater aquifers.

– Salt water intrusion can lead to contamination of drinking water sources and other consequences.

– Oceans
– Aquifer

#106 Dams
– A barrier that impounds water or underground streams.

– Reservoirs created by dams not only suppress floods but also provide water for such activities as irrigation, human consumption, industrial use, aquaculture, and navigability.

– Dam removal
– Beavers

#107 Dam Removal



– The process of removing out-dated, dangerous, or ecologically damaging dams from river systems.

– Dam Removal Strategies Removal work on the Glines Canyon Dam began September 15, 2011 and at Elwha Dam on September 19.

– Dams
– Beavers

#108 Agriculture Effect On Freshwater
– Excessive water use for agriculture is leaving rivers, lakes and underground water.

– Agriculture effect on freshwater can be both negative and positive.

– Farming
– Agriculture

#109 Recreational Effect On Freshwater
– Human impact that effects the water.

– Things like climate change can cause recreational effect on freshwater.

– Agriculture effect on freshwater
– Fishing

#110 Non-point Source Pollution
– Rainfall or snowmelt moving over and through the ground.

– Non-point source pollution, unlike pollution from industrial and sewage treatment plants, comes from many diffuse sources.

– Water pollution
– Air pollution

#111 Point Source Pollution
– Any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack.

– Factories and sewage treatment plants are two common types of point sources.

– Non-point source pollution
– Water pollution

#112 Primary Wastewater Treatment
– A sequence of steps used to ensure waste water gets treated.

– Sewage treatment may also be referred to as primary waste water treatment.

– Sewage treatment
– Secondary waste water treatment

#113 Secondary Waste Water Treatment
– Treated irrigation water for property owners within the Coalville City limits.

– Secondary water that has been treated is to be used for watering lawns, gardens, fields, etc.

– Primary waste water treatment
– Tertiary waste water treatment

#114 Tertiary Waste Water Treatment
– The final cleaning process that improves wastewater quality before it is reused, recycled or discharged to the environment.

– Tertiary waste water treatment removes remaining inorganic compounds, and substances, such as the nitrogen and phosphorus.

– Primary waste water treatment
– Secondary waste water treatment

#115 Sludge
– Thick, soft, wet mud or a similar viscous mixture of liquid and solid components, especially the product of an industrial or refining process.

– Sludge is also described as dirty oil, especially in the sump of an internal combustion engine.

– Oil
– Gas
