Unit 6 Managing Water Supplies quizs

soil moisture

• the amount of water found in the soil

• the type of soil that retains water

• the process of water evaporation from soil

• the level of nutrients in the soil

natural recharge

• Water that moves from the land surface or unsaturated zone into an aquifer.

• Water that is artificially added to an aquifer through human activities.

• Water that evaporates from the surface and returns to the atmosphere.

• Water that is stored in glaciers and ice caps.

salt water intrusion

• The movement of salt water into fresh water aquifers

• The process of desalination of seawater

• The contamination of freshwater by industrial waste

• The natural filtration of water through soil

perched aquifer

• An aquifer that occurs below a regional water-table.

• An aquifer that occurs above a regional water-table.

• An aquifer that is completely dry and has no water.

• An aquifer that is formed by the melting of glaciers.

permeable

• A material that allows liquid to pass through (sandstone is a permeable rock type)

• A material that does not allow any liquid to pass through

• A material that absorbs liquid but does not allow it to pass through

• A material that only allows gases to pass through

aquitard

• A zone within Earth that restricts the flow of groundwater from one aquifer to another; comprised of either clay or layers of non-porous rock

• A layer of rock that allows water to flow freely between aquifers

• A type of well used for extracting groundwater

• A geological formation that stores large quantities of oil

sanitation

• The provision of clean drinking water and sewage disposal

• The process of cleaning and disinfecting surfaces

• The management of solid waste and recycling

• The treatment of wastewater for agricultural use

artesian well

• A type of well that is dug into the ground to access underground water.

• A well where underground water is under pressure and rises to the surface when punctured.

• A well that only collects rainwater.

• A well that is used for irrigation purposes.

Unconfined aquifer

• An aquifer where the water table is at atmospheric pressure and has no impermeable layer above it.

• An aquifer that is completely filled with water and has a pressure greater than atmospheric pressure.

• An aquifer that is located below the water table and is surrounded by impermeable rock layers.

• An aquifer that can only be accessed through wells drilled into the ground.

water table

• An underground boundary between the soil surface and the area where ground water saturates the rocks

• A layer of soil that is always dry

• The surface of a body of water

• A type of water purification system
