Environmental Studies UNIT 5
Terms in this set (43)
the non-living components of the environment
the living components of the environment (flora, fauna, microorganisms)
Energy sources which do not burn fossil fuels (do not generate CO2) suchas, nuclear, tidal, wind, solar, and hydroelectric
precipitation such as rain, sleet, or snow, that contains a high concentration of acids, often because of the pollution of the atmosphere
the removal of underground water from the aquifer faster than the aquifer can be recharged
type of waste which can be broken down, in a reasonable amount of time, into its base compounds by micro-organisms and other living things, regardless of what those compounds may be.
the number and variety of organisms in a given area during a specific period of time. more species = more diversity
organic (once living) matter that can be a source of energy - when burned known as biofuel
The largest number of individuals of one species that an ecosystem can support or sustain over time.
chemical released by aerosols which breaks down and dissolves the ozone layer
the preservation and wise use of natural resources
The removal of large areas of forests for human purposes
a method of timber harvesting where all trees are removed
a method of timber harvesting where mature trees are removed and younger growth trees remain
"Good food" the introduction of nitrogen, phosphates and fertilization into water, causes plant overgrowth and stagnation which removes vital oxygen from the water and causes imbalance in food web
Ecological (carbon) footprint
The concept that resources used is directly related to the wastes generated (more developed=larger)
an abnormal warming of surface ocean waters in the eastern tropical Pacific,
nonrenewable energy resource formed from the remains of organisms that lived long ago; examples include oil, coal and natural gas
food web(multiple connections) and food chain(linear connection)
The graphic which depicts species interdependence and the movement of energy from one organism to another.
energy produced by heat within the Earth
An increase in the average temperature of Earth's surface.
The natural process that occurs when greenhouse gases in the atmosphere absorb and reradiate thermal energy from the sun.
electrical energy produced by falling water
an exotic species that causes ecological or economic problems in their new habitat.
is characterized by unusually cold ocean temperatures in the eastern equatorial Pacific
any natural substance that humans use, such as, sunlight, soil, water, metals, minerals, wind, geothermal heat, flora or fauna
nonpoint source pollution
refers to both water and air pollution from diffuse sources. Nonpoint source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Nonpoint source air pollution affects air quality from sources such as smokestacks or car tailpipes
resource that is formed at a rate slower than the rate at which it is consumed (usage more than can be replenished)
energy released by a fission or fusion reaction; the binding energy of the atomic nucleus
a highly reactive form of oxygen. In the upper atmosphere, ozone forms a protective layer that shields us from the sun's ultraviolet rays
liquid mixture of complex hydrocarbon compounds; used widely as a fuel source
point source pollution
a single identifiable source of air, water, thermal, noise or light pollution. A point source has negligible extent, distinguishing it from other pollution source geometries.
the contamination of a natural ecosystem, usually due to human activity
All the organisms of the same species that live in the same area at the same time.
using less, using over again, and making new materials from old things
Process of planting trees to replace trees that have been cut or burned down.
natural resource that can be replaced at the same rate at which it is consumed
energy received by the Earth from the sun in the form of radiation
The physical growth of urban areas as a societal change, including the movement of people from rural to urban areas
use of a windmill to drive an electric generator
actions that can continue indefinitely, meeting the resource needs of the present without compromising the ability of future generations to meet their own needs
actions that meet the needs of the current population without making provisions for future generations. Humans cannot continue these actions indefinitely. All resources will be consumed
gasses with a high specific heat capacity that trap heat in the Earth's atmosphere - for example, CO2, methane, and water vapor
