Terms in this set (82)
underground geological formation able to store and yield groundwater; water exists in spaces between rock, sand, and gravel
the variety and complexity of all forms of life: plants, animals, micro-organisms, their genes and their ecosystems
substance that makes water or other substances impure and unfit for consumption or an intended use
functional natural unit with interacting biological, chemical and physical components in a system who boundaries are defined by the flow of energy, materials and organisms; ecosystems often overlap with one another; a watershed is just one of many types of ecosystems
organisms that are in danger of extinction throughout all or a large portion of its range because of a less of change in habitat, over-exploitation, predation, competition, disease, disturbance or contamination
wearing down or washing way of the soil and land surface by the action of water
increase in nutrient levels (nitrogen and phosphorous) in a body of water which can result in increased algae growth and decrease oxygen levels, thereby reducing quality of aquatic environment for other organisms; can be a natural process or induced by human inputs
the study of the classification, description and origin of land forms such as mountains, valleys, streams, etc.
areas of undeveloped or previously developed land with some portions of natural habitats for plants and animals; can take the form of parks or nature preserves; places for opportunities for recreation, reflection, and relaxation
environment, area and conditions where an organism lives
(as defined by National Council on Invasive Species) is " a species that is non-native or alien to the ecosystem under consideration and whose introduction causes or is likely to cause economic or environmental harm to human or environmental health".
species whose presence contributes to the diversity of an ecosystem and whose extinction would lead to the extinction of other forms of life
process of returning the ecological system to an undisturbed (or pre-disturbed) condition
organisms that are likely to become endangered throughout all or a large portion of its range in the foreseeable future if environmental conditions begin to or continue to deteriorate
water that seeps down through the soil and fills spaces between soil, rock and sand particles; slowly moves underground at a downward angle and may eventually seep into streams, lakes, and oceans; natural resource that is used for drinking, recreation, industry, and growing crops.
non-point source pollution
occurs when water delivers contaminants from large areas of land (not specific location) to watershed or body of water; can include sediment, nutrients, organic and toxic substances
point source pollution
occurs when pollutants are discharged from any identifiable point, including: pipes, ditches, channels, sewers, tunnels, and containers
alteration in chemical, biological or physical quality of the environment, or any of its components, that renders it less suited for certain uses
pertaining to a body of water such as a steam, river, or lake; of or on the bank of a body of water
vegetated area along banks of body of water; provides shade and protects body of water from land uses
precipitation that flows over land to surface steams, rivers, streams, pongs, floodwater, and runoff
treats household sewage by letting solids decompose and settle in a tank and letting liquid absorb into the soil; used when a sewer line is not available to carry wastes to a sewage treatment plan
capable of being dissolved in other substances
man-made opening on road through which runoff flows into underground system
water above the surface of the land; includes: lakes, rivers, streams, ponds, floodwater, and runoff
water that contains unwanted materials from homes, businesses, and industries
waste water treatment
any process used to change the quality of waste water in order to make it more acceptable to humans and the environment
chemical, physical, and biological characteristics of water with respect to a particular use
land area from which water, sediment and dissolved materials drain into a body of water such as a stream, lake, or river; also called drainage basin; water sheds vary greatly in size
land saturated with water at some or all times of the year; determines the nature of soil development and the types of plant and animal communities; examples of wetlands include: marshes, bogs, swamps, etc.
rainfall or snow that contains a lower then normal pH
any chemical, biological, or physical change in water quality that has a harmful effect on living organisms or makes water unsuitable for desired usage.
released directly into the air
formed as a result of a chemical reaction in the air
sick building syndrome
buildings with particularly poor air quality
air pollution that hangs over urban areas and reduces visibility
the air above is warmer then the air below
clean air act
a law that took effect in 1970. initially it required to set and enforce for the 6 criteria pollutants but when it was amended in 1990 some other provisions were added
the 6 criteria pollutants are...?
When did the clean air act take effect?
When was the clean air act amended?
toxic and hazardous air pollutants
protection of ozone layer
leakage of volatile organic compounds
Additional provisions to the clean air act are?
volatile organic compounds
organic (carbon-based) gases like methane that can decompose or react easily, forming carbon dioxide or carbon monoxide in the air.
- spilled/leaking gasoline that evaporates
- paint and paint cleaners
what are the biggest sources of volatile organic compounds?
7 = Neutral
Less than 7 is Acidic
Greater than 7 is Basic
What does the pH scale range from? What is acidic, neautral, basic, etc...?
Was passed in 1989. Countries agreed to phase out CFC's by 2000. CFC levels have decreased and the ozone layer is beginning to recover
Main pollutant behind ozone depletion
EPA estimates an average of 50,000 people die prematurely from illnesses related to air pollution.
What are the effects on human health because of air pollution?
environmental protection agency
is dumping water into a river, lake, or sea that is either much warmer or much colder than normal. (Oxygen levels in water decreases as temperature increases)
-leftover mining waste
-organic waste (manure)
