Hydrosphere
All the water found on, above and under the Earths surface.
100
(True/False) The sea floor moves only when there is an upwelling.
False. The sea floor is constantly moving.
100
Is zooplankton a producer?
No. It is animal like.
100
Are a large amount of bioindicators a good or bad sign for the waters health?
Good, because that means many animals can survive there.
100
Something harmful that is released into the environment.
Pollution
200
An area of land that drains water into a stream, river, lake or other body of water.
What is a watershed?
200
(True/False) Phytoplankton eat Zooplankton.
False. Zooplankton eat Phytoplankton.
200
A long narrow opening (fissure) in the earths surface that releases gases that heat the water around it.
Hydrothermal vent
200
(true/false) Cold water holds less dissolved oxygen (D.O) than warm water.
False. It can hold more.
200
Pollution that comes from many places
Non-point source pollution
300
Where is most of Earths freshwater located?
Icebergs, snow, glaciers, permafrost
300
(True/False) Algae are producers.
True. They are producers, since they make their own food.
300
Where freshwater meets saltwater Where the tidal meets the stream "Nursery of the Sea"
Estuary
300
(true/false) A high pH level is a good for the water.
False, because water is the healthiest when the pH level is neutral (7).
300
Pollution that comes from a single, identifiable site.
Point source pollution.
400
Out of all of the Earths water, what percentage is is freshwater?
3%
400
(True/False) Upwelling is bad for the ocean because it brings bottom ocean organisms to the surface. Which disrupts the circle of life.
False, because it brings cold water nutrients to the surface.
400
(true/false) Great whites are secondary consumers.
False, they are predators. All sharks are at the top of the food web (tertiary consumers) except whale sharks.
400
Do high pH levels make water look cloudy or clearer?
Cloudy, because of the high amounts of algae present.
400
Ex. Sand, grit, oil, and gasoline from city and suburban streets.
Non-point source pollution
500
What is the Pamlico sound?
Estuary/Sound
500
What is chemosynthesis?
Process by which some organisms use the energy stored in chemical bonds to make their own food.
500
(true/false) No animals can prosper around hydrothermal vents.
False, many animals can.
500
A measure of how acidic/basic the water is.
pH
500
Ex. Release of dishwater or sewage from homes directly into water systems.
Point source pollution.
