Oceanography
Earth Science-Oceanography
| Question | Answer |
|---|---|
| is a science that draws on the methods and knowledge of geology chemistry physics and biology to study all aspects of the world ocean | oceanography |
| is the measurement of ocean depths and the charting of the slope of topography of the ocean floor | bathymetry |
| is an acronym for sound navigation and ranging | sonar |
| is a small underwater craft use for deep sea research | submersible |
| the ocean basin floor and the mid ocean ridge | continental margins |
| is the gently sloping submerged surface extending from the shoreline | continental shelf |
| is the making of the seeward edge of the continental shelf | continental slope |
| are cut into the continental slope | submarine canyon |
| are occasionsl movements of dense sediment rich water down the continental slope | turbidity currents |
| the steep continental slope merges | continental rise |
| continental margin and mid ocean ridge | basin floor |
| are deep extremely flat features | abyssal plains |
| the submerged volcanic peaks that dot the ocean floor | seamounts |
| occurs at a divergent plate boundary where two lithospheric plates are moving apart | seafloor spreading |
| is sediment that originates on land | terrigenous sediment |
| is sediment that is biologic in origin | biogenous sediment |
| produced from the calcium carbonat shells of organisms | calcareous ooze |
| mineral that crystallize directly from ocean water through varius chemicals reactions | hydrogenous sediment |
| compact chemical structures made of water and natural gas | gas hydrates |
| are hard lumps of manganese and other metals that preticipitate around a smaller object | manganese nodules |
| total amount of solid material dissolved in water | salinity |
| is the layer of ocean water between 300 meters and 1000 meters where there is a rapid change of temp with depth | thermocline |
| mass per unit volume | density |
| organisms such as algae animals bacteria that drift with ocean currents | plankton |
| alage that undergo photophysis | phytoplankton |
| animal plankton | zooplankton |
| animals capable of moving independently of the ocean currents | nekton |
| organisms living on or in ocean bottom | benthos |
| production of organisms compounds from inorganic substances through photosynthesis or chemosynthesis | primary productivity |
| use of light/energy to convert water and carbon dioxide into energy rich glucose molecules | photosynthesis |
| is the process by which certain microorganisms create organic molecules from inorganic nutrients using chemical energy | chemosynthesis |
| is all sequence of organisms through which energy is transferred starting with the primarily producer | food chain |
