Human Impact

TermDefinition
Groundwater water that collects underground in cracks and spaces in rock
Surface water any body of water above ground, including streams, rivers, lakes, wetlands, reservoirs, and creeks
Watershed a land area that channels rainfall and snowmelt to creeks, streams, and rivers and eventually to outflow points, such as reservoirs, bays, and the ocean
Aquifers a body of porous rock or sediment saturated with groundwater.
Artificial reef a human-created freshwater or marine benthic structure.[1] Typically built in areas with a generally featureless bottom to promote marine life, it may be intended to control erosion, protect coastal areas, etc.
Dependence the state of being conditional or contingent on something, as through a natural or logical sequence
Irrigation the controlled application of water for agricultural purposes through manmade systems to supply water requirements not satisfied by rainfall.
Ocean systems interconnected system that has regions. Water and ocean life move between these regions, up and down the water column. Ocean water circulates around the globe through ocean currents that are either wind-driven currents or density-driven currents.
Oil spills the release of a liquid petroleum hydrocarbon into the environment, especially marine areas, due to human activity
Overfishing catching too many fish at once, so the breeding population becomes too depleted to recover.
Recharge zones the place where water is able to seep into the ground and refill an aquifer because no confining layer is present.
Runoff the part of the water cycle that flows over land as surface water instead of being absorbed into groundwater or evaporating.
Springs a water resource formed when the side of a hill, a valley bottom or other excavation intersects groundwater at or below the local water table, below which the subsurface material is saturated with water.
Water table describes the boundary between water-saturated ground and unsaturated ground.
Wells a hole drilled into the ground to access water contained in an aquifer.
