All Flashcards
What is irrigation?
Artificially watering crops.
What is salinization?
Accumulation of salt in the soil due to water evaporation after irrigation.
What are aquifers?
Underground layers of rock or soil that hold groundwater.
Define drip irrigation.
Water delivered directly to plant roots through underground hoses.
Define flood irrigation.
Water is dumped onto a field and allowed to spread.
Define furrow irrigation.
Water flows through trenches dug between rows of crops.
Define spray irrigation.
Water is sprayed over the field from a central location.
Define groundwater.
Water held underground in the soil or in pores and crevices in rock.
Define water table.
The upper level of the saturated zone of groundwater.
What is aquifer depletion?
The overuse and subsequent reduction in groundwater levels within an aquifer.

Define permeability.
The state or quality of a material or membrane that causes it to allow liquids or gases to pass through it.
Cause: Water evaporates after irrigation. Effect?
Salt accumulates in the soil (salinization).
Cause: Overuse of aquifers. Effect?
Aquifer depletion and potential water scarcity.
Cause: Flood irrigation. Effect?
Water waste, soil erosion, and nutrient runoff.
Cause: Drip irrigation. Effect?
Reduced water waste and decreased risk of salinization.
Cause: Increased soil salinity. Effect?
Inhibited plant growth and reduced crop yields.
Cause: Depletion of the Ogallala Aquifer. Effect?
Water scarcity for agriculture in the Great Plains.
Cause: Excessive groundwater pumping. Effect?
Land subsidence and saltwater intrusion in coastal areas.
Cause: Deforestation in watershed areas. Effect?
Increased runoff and decreased groundwater recharge.
Cause: Climate change leading to prolonged droughts. Effect?
Increased demand for irrigation and accelerated aquifer depletion.
Cause: Implementation of water-efficient irrigation technologies. Effect?
Reduced water consumption and improved crop yields.
