This
week's vocabulary is A lot at once. There
is no test, but students will be expected to understand this vocabulary in
preparations for our field trip on Monday.
fresh water Naturally occurring water with low amounts of salt. Ocean
water contains approximately 3.5 % salt and is not safe to drink for humans.
groundwater water that is located below the Earth's surface in the soil.
pollution introduction of foreign substances or energy to an
environment such that organisms in the environment are adversely affected.
potable referring to water, safe for humans to drink.
renewable resource a resource that is replenished after it is
used by living things in a short period of time. Generally, if the overall
concentration of the resource on Earth does not change over time, it is
considered renewable.
reservoir large holding area for fresh (or potable) water. This term
may also refer to a generalized part of the water cycle (e.g. groundwater,
glaciers).
water cycle a generalized representation of the transitions and movements
water undergoes throughout the atmosphere, hydrosphere, geosphere and
biosphere. The water cycle is not an actual description of a path of water
through time or space, but a summary of the transitions water undergoes as ice,
water, and vapor.
watershed the entire geographic area directly affected by a body of
water.
percolation movement of water through a partition or medium, usually
accompanied by the water dissolving substances as it moves through the
partition.
porosity the amount of space between particles in a partition or
medium.
riparian referring to rivers and streams.
riparian buffer zone an area near riverbanks where plants with
extensive root systems are established to prevent excessive runoff.
sediment soil or other material deposited by running water, wind, or
other moving matter.
Tributary a smaller stream or river that
empties into a larger stream or river.
dissolved oxygen The amount of oxygen dissolved in a
water sample. Dissolved oxygen is an indicator of whether the water source can
support life.
macroinvertebrates small invertebrates that have various
tolerances for pollution. If certain sensitive macroinvertebrates are thriving
in a watershed, that watershed is probably not polluted.
non-point source pollution a type of pollution that occurs because
of widespread contamination, where no one source is the cause (e.g.
agricultural runoff)
pH a
measure of the acidity or alkalinity of a water sample. A low pH indicates acid
conditions, and a high pH indicates alkaline conditions. Living things can only
survive in a narrow range of pH (near pH 7).
point source pollution a type of pollution that occurs from a
specific location or a specific action (e.g. dumping raw sewage at a broken
line).
Topography physical features of a region
Abiotic Nonliving
Biotic Living
Thermal Heat energy
Clarity clearness
Turbidity A measure of how clear water is.
Aerated Filled with air
Photosynthes 6CO2 + 6H2O + light --> C6H12O6 + 6O2
Salinity A measure of the amount of dissolved salts in a given amount of
liquid
Algal The
rapid growth of a population of algae
ppm parts
per million
ppb parts
per billion
ppt parts
per trillion
anoxic no
oxygen
Nitrate Nitrate is a nutrient needed by all aquatic plants and animals to
build protein. The decomposition of dead plants and animals and the excretions
of living animals release nitrate into aquatic system.
Terrestrial (adj.) relating to the land (Elephants are terrestrial
animals.)
Biodiversity The number of species within a specific
habitat.
Biomonitoring biological approach moni-toring an ecosystem'
s health
