Artificial reef
Human made structure that is sunk into the coastal Ocean to provide feeding and hiding places for fish
Upwelling
When warm surface water is replaced by cold nutrient rich water from the deep ocean
How does upwelling affect the Marine food web
The things brought up by upwelling are eaten by plankton and organism that eats plankton get the nutrients
Which 2 factors effect density of water at the poles which cause deep ocean currents to form
Salinity and temperature
How does the Suns energy affect the oceans connection currents
The unequal heating of the earth causes density differences, which makes convection currents
The new moon is always positioned between the
Sun and earth
What layer of the atmosphere are jet steams
Troposphere
What causes jet streams to shift north or south
Coriolis effect
What 3 factors affect surface currents
Continental deflection, Coriolis effect, global winds
Red shift
Moving away
