AICE Environmental Management Flashcards
sustainability
to meet the needs of the present without compromising the future
evaporation
water changing from the liquid state to a gaseous phase through the uptake of energy
transpiration
process by which water vapour moves through and out of a plant before being released into the atmosphere
condensation
water changes from gas to liquid through the release of energy, warming the environment
precipitation
condensed water in clouds falls back to the surface of the earth
interception
precipitation being blocked from reaching the ground by a plant foliage/canopy, or even a leaf filter
through-fall and stem-flow
raindrops that are intercepted by plants collecting on the leaves and falling through the foliage and onto the soil
run-off or surface water flow
water collecting on the surface of the land and flowing over the ground
infilltration
process during which water is absorbed by the soil
through-fall
water flowing through the soil
groundwater
water below the earth’s surface usually within a few hundred feet
photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
salinity
measurement of salt in water or soil
biosphere
life-supporting zone where the atmosphere, hydrosphere, and lithosphere meet
biomes
large-scale ecological zone characterized by its soil, climate, vegetation, and wildlife
scientific method
a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses
gross national income (gni) per capita
the measure of the total income of a country divided by the number of people in that country
biome
a large naturally occurring community of flora and fauna occupying a major habitat
ecosystem
a biological community of interacting organisms and their physical environment
population
al the inhabitants of a particular areac
community
a group of organisms living in the same place or having a particular characteristic
habitat
a natura home or environment of an organism
niche
comfortable or suitable environment
water cycle
continuous movement of water on, above, and below the surface of the earth
greenhouse effect
a process that occurs when gases in Earth’s atmosphere trap the sun’s heat
population dynamics
the study of how and why populations change in ize and how they can be managed
migration
the movement of peoples from one place in the world to another
population distribution
the way in which the population is spread out across a given area
population density
the number of people living in a square kilometre (or other unit of area)
