Vocabulary Word List Water Fest 2006
aquatic insect: An insect that spends part or all
of its life in the water.
aquifer: permeable, saturated geologic unit that
can transmit significant quantities of water
atmosphere: blanket of gases surrounding our planet
benthic macroinvertebrate: Bottom dwelling aquatic
organisms, without a backbone, which can be seen with the naked eye.
cave: channel formed by groundwater dissolving limestone
or dolomite bedrock
confined aquifer: bounded above and below by confining
beds - also called artesian aquifer
diversity: Number of different types of organisms
that can live together in a certain habitat
dolomite: limestone with considerable amounts of
ecosystem: the sum of all plants, animals, and other
living things, plus their surroundings (soil, climate). Living things
within an area are dependent upon each other and the resources available.
Example: a pond with its bottom soil and plant growth that feeds fish,
and other fish that feed on each other. Each member of the system provides
support for other parts.
environment: the total conditions that affect an
organism such as climate, soil, water, and other living things.
erosion: the wearing away of the land surface by
wind or water.
geology: the scientific study of the origin, history,
and structure of the earth.
gills: Structures which organisms that live in water
use to get oxygen.
gravity: the force which attracts any object of any
mass towards another object of any mass.
groundwater recharge: infiltration of water from
the earths surface into the groundwater system.
habitat: The place where animals, fish, and plants
live. In a stream it includes pools, riffles, deep water, undercut banks,
vegetation, gravel and rocks.
head - thorax - abdomen: Three main body parts of
karst: geographic areas where the land surface is
formed by the dissolving of soluble bedrock. A karst region is characterized
by caves, sinkholes, and losing streams and springs.
larva: the immature form of an insect that transforms
through complete metamorphosis
limestone: sedimentary rock composed mainly of calcium
carbonate. Formed by the deposits of aquatic lime- secreting organisms
losing stream: a stream in which a section of the
stream is losing water into the subsurface material
macroinvertebrate: organisms (aquatic insects) that
lack a backbone and can be seen with the naked eye
metamorphosis: When insects change from juvenile
to adult involving the reorganization of body tissue. Considered its life
cycle, including egg, larva, pupa and adult.
moderately tolerant organism: organism that can survive
with some pollution
nymph: the immature form of an insect that transforms
through complete metamorphosis
percolate: to move through a permeable substance;
penetrate; to ooze or trickle down through a permeable substance
pollution: any substance that changes our environment
in a harmful way and stresses living things. The quality of the environment
pollution run-off (non point): coming from a general
or non-specific location or cause
point source pollution: a stationary source of pollution,
such as a discharge pipe
non-point source pollution: an unknown pollution
source, such as drainage from pasture land
precipitation: water from the atmosphere that falls
to the ground as rain, snow, or sleet, or hail
predator: living things which prey upon and eat other
living things as a source of food
pupa: in insects with complete metamorphosis, a stage
where the immature insect is enclosed in a tissue- like cocoon, where
reorganization occurs and an adult emerges. (Usually an immobile stage)
riparian zone: Land that is located on the banks
of a body of water, and 10 or more feet parallel to it.
run- off: fresh water from precipitation and melting
ice that flows on the ground surface into nearby streams, lakes, wetlands,
sensitive organism: an organism which dies with exposure
to a low level of pollution
silt: very fine particles of earth often transported
by water and deposited as sediment
sinkhole: depression in the earths surface
caused by the subsurface removal of soil and rock. Collapsed caves form
somewhat sensitive organisms: organisms which can
survive with some pollution
spring: an opening on the earths surface where
water discharges- where the water table intersects the earths surface
tolerant organism: organisms which can survive in
unconfined aquifer: aquifer where the water table
is the upper boundary of the aquifer
water cycle: the system by which Earth's water is
collected, purified, and distributed from the environment to living things,
and back to the environment
water pollution: the addition of harmful or objectionable
material to water in concentrations or sufficient quantities that adversely
affect its usefulness or quality
water quality: a rating given to a body of water
based on the diversity of life that can live there
watershed: The land area from which surface run-off
drains into a stream channel, lake, reservoir or other body of water,
also called a drainage basin
water table: the upper boundary of an unconfined
well: a hole that is drilled into the ground to a
depth below the water table
