Term
Industrial Revolution
Definition
late 18th & early 19th centuries, major changes in agriculture, manufacturing, production, and transportation had a profound effect on the socioeconomic and cultural conditions in Britain
Term
New Deal
Definition
FDR 1933-1938 supported corn price, encouraged idling of fields

Term
Photochemical Smog
Definition
particulates, smog, smoke, soot. sunlight + car exhaust = worse chemicals
Term
Runoff
Definition
precipitation from rain that flows overground
Term
Sewage
Definition
mainly liquid wastewater produced by humans which typically consists of washing water, feces, urine, laundry waste and other material which goes down drains and toilets fro households and industry
Term
Non-Point Source Pollution
Definition
poorly defined and scattered over broad areas
ex. runoff or groundwater discharge carrying pollutants
Term
Point Source Pollution
Definition
discharge of substances at a distinct location
ex. factories, sewage systems, oil wells; easier to identify
Term
Biological Oxygen Demand (BOD)
Definition
used as a measure of the degree of water pollution, higher BOD = more pollution
Term
Submerged Aquatic Vegetation (SAV)
Definition
require light to penetrate water column, can be used to indicate water quality
Term
Cultural Eutrophication
Definition
driven by human activities (farming)
occurs rapidly
sources: sewage effluent, stormwater runoff

Term
Transgenic Organism

contain genes from another organism
Term
Super Stimulus
