Oceans
What is the amount of salt water on Earth
97%
What words means the amount of salt in the water
salinity
Pollutants discharged from a single identifiable location is called what?
point source pollution
an organism that makes its own food (plants)
autotrophs or producers
The law that states that mass is neither created nor destroyed in ordinary chemical and physical changes.
Balanced equation
law of conservation
What has the biggest impact on tides?
Moon
The measure of the clarity of the water (how clear is it?) High #########= dirty water
turbidity
the area where a freshwater stream or river merges with the ocean. Often a nursery for young.
estuary
what is it called when the production of light by means of a chemical reaction in an organism occurs
Bioluminescence
The amount of energy required to raise the temperature of 1 gram of a substance by 1 degree celcius...amount of heat required to increase the temperature of water
Specific Heat
What material is the most dangerous pollution in our oceans, it can strangle, drown, or choke marine animals or poison the ecosystem by ingestion and polymers that can't be broken down.
Plastic
What can harm filter feeders and interfere with photosynthesis.
hint:soil
excess sediment from runoffs
a widely spread source of pollution that is difficult to link to a specific point of origin is called ?
Non-Point Source Pollution
Species that serve as early warnings that a community or ecosystem is being degraded.
Bio-Indicator species
Excess amount of Nitrogen, Phosphorus, & Sulfur from FERTILIZER can cause what to happen?
Algae Bloom
What provides
-cooler temperatures
-water has high specific heat: absorbs sunlight and doesn't warm up as fast.
-Keeps temperatures moderate.
Effects of Ocean Currents
Causes moving air and water to turn left in the southern hemisphere and turn right in the northern hemisphere due to Earth's hemisphere and rotation.
Coriolis Effect
When cold water from the bottom of the ocean floor brings nutrients to the surface.
upwelling
A type of pollution that has excessive amounts of soil particles that enter the water as a result of erosion, causing water to cloud up and prevent sunlight to start the food chain-algae to fish. Makes it harder for humans to clean water.
Sediment Pollution
A way to clean up pollution like oil spills and other types of pollution using bacteria or a living species
Bioremediation
Why are the oceans important?
larges biodiversity in world
moderates Earth's temperature
Moderates Earth's climate
What can cause water pollution, some examples
run-off from farms or cities
excess fertilizer or waster water
oil spills
landfills waste seeping in watersource
A Natural process by which nutrients, particularly phosphorus and nitrogen, become highly concentrated in a body of water, leading to increased growth of organisms such as algae or cyanobacteria is called ?
eutrophication
An increase in the concentration of a chemical in specific organs or tissues at a level higher than would normally be expected is called?
Ex. Plastic build up in a fishes tissue
bioaccumulation
treatment of a contaminated area or pollution by injecting it with a chemical compound that reacts with the pollutant to produce harmless products.
