a measure of the cloudiness of a substance
turbidity
cloudy with a chance of meatballs
NTU
hydrocloudiology
the results of turbidity are
temperature increase caused
by increase of sunlight absorption;
darker water holds more heat
water that is crystal clear
water that precipitates as it condenses
dirty rain
levels on the pH scale range from
Close to neutral (7). Levels range from
1 to 14 with acids at the lower
numbers and bases higher
the measure of acidity
acid example: lemon juice
base example: baking soda
15-22
natural conditions (especially in
swamps) dumping waste and farm
runoff
what can cause a change in pH?
natural conditions (especially in
swamps) dumping waste and farm
runoff
turbulent water, depth, and
plant growth
High levels of variety = healthy aquatic
ecosystem
increased levels of phytoplankton,
sediment, erosion, water algae
amount of oxygen dissolved
in water
dissolved oxygen
02 indicator from the CO2 regulator
turbidity
pH levels
causes of changes in dissolved oxygen are
turbulent water, depth, and
plant growth
how much ocean water you can drink with a really big straw
pooting in the pool
supercalifragilisticexpialidocious
the measure of how much heat is in water is called
temperature
cold
hot
dissolved oxygen levels
what can cause a change in temperature in water?
turning the Earth Air Conditioner up
time of year, source of water
turbidity levels, depth, shade,
and vegetation
Igneous rock from volcanoes on land
natural conditions (especially in
swamps) dumping waste and farm
runoff
nitrates/phosphates are
compound found in most
fertilizers; nitrogen-based
a measure of heat
amount of oxygen dissolved
in water
a measure of the cloudiness
of a substance
the results from rising nitrate levels would be
increase plant production & fish
population resulting in
overcrowding
with no D.O., bio-indicators
with no survive
a small change of 2 results in
a water system with 100 times a
difference in acidity
DEATH!!!!!!!
macroinvertibrates found
living in water that are
sensitive to pollution are
bio-indicators
bugs and stuff
dissolved oxygen testers
choose the answer that starts with bio
High levels of variety in micro-invertabrates= healthy aquatic
ecosystem
true
false
