Water Movement
Movement of water caused by the pull of gravity from the sun and the moon.
What are tides?
Organisms that float on or near the surface.
What are plankton?
Area between high-tide and low-tide.
What is the intertidal zone?
Warmer, less salty water is this.
What is less dense?
(Less dense water will rise.)
Plant life found along the continental shelf.
What are kelp forests and coral reefs?
These are caused by winds and the Coriolis effect.
What are surface currents.
Organisms that are free-swimming and move throughout the ocean.
What are nekton?
Area between low-tide and the edge of the continental shelf.
What is the neritic zone?
Colder, more salty water is this.
What is more dense?
(More dense water will sink.)
Hydrothermal vents occur in this layer.
What is the deep layer?
These are caused by differences in temperature, salinity, and density.
What are deep currents?
Organisms that stay in one place or move around on the ocean floor.
What are benthos?
Area that starts at the edge of the continental shelf and covers the deepest parts of the ocean.
What is the oceanic zone?
Cold, nutrient rich water from the deep rises to the surface and produces unusually cold conditions.
What is upwelling?
(La Nina is associated with this.)
Continuous flow of ocean in a certain direction.
What is a current?
Movement of water caused by waves that strike the shore at an angle.
What are longshore currents?
The benefits of bioluminescence for certain marine organisms.
What are organisms that can produce their own light in the deep zone can attract a mate or prey or escape a predator?
Topmost layer of ocean where the sunlight reaches and is where the water is warmest.
What is the surface layer?
Unusually warm trade winds prevent upwelling when this occurs.
What is El Nino?
The transfer of energy from point to point through matter.
What are waves?
A strong flow of water that returns to sea.
What are rip currents?
Organisms that can live in extreme conditions such as high salinity or heat in which most organisms would never survive.
What are extremophiles?
Ocean layer that rapidly decreases in temperature.
What is the transition layer?
The Coriolis effect, gravity, wind, and density affect this.
What are currents?
Reasons a brine pool is unique.
What are brine pools are located on the ocean floor, have unusually high salinity, and the water does not diffuse with the surrounding ocean water?
