LAB 2 Flashcards
What is the order of a food chain?
primary producer-pimary consumer-secondary consumer-decomposer
What are the two ways primary procures get food?
photosynthesis (convert sunlight to energy) and chemosynthesis (convert chemicals to energy)
The ratio of Carbon, Nitrogen, and Phosphorus
106:16:1
Does latitude affect salinity?
increases with latitude (ice takes water away) evaporation at equator
What is the Driving Force, Depth Affected, Circulation Patterns, Relative Speeds of Currents in Deep Circulation?
DF: density (temp and salinity) DA: about 4000 m CP: deep, RS of currents: really slow 2000 yrs
What is Driving Force, Depth Affected, Circulation Patterns, and Relative Speeds of Currents of SURFACE CIRCULATION?
DF: trade winds, DA: 100 m, CP: surface, and RS of currents: quick
(8) What is surface circulation Driven By?
(8) What is the Coriolis Deflection?
(8) What is the Eckman Transport?
(8) What is the diagram of the Eckman Transport?
(8) What is the El Nino?
(8) What changes between normal and El Nino times?
(8) Diagram of Northern Hemisphere
(8) What is the difference between spinning and moving?
(7) How does temperature and salinity affect density?
(7) What are the calculations to convert density to g/cm cubed
(7) What drives deep ocean circulation?
(7) What is a deep ocean circulation path called?
global conveyor belt
(7) Why is Antarctic bottom water so dense?
(7)What are the relative speeds of surface and deep circulation?
(8) What is the crest?
peak of the wave
(8) What is the trough?
bottom of the wave
(8) What is the wavelength?
distance between peaks or troughs
(8) What is the wave period?
time it takes for a wave to move a instance of one wavelength
(8) What is the wave frequency?
number of waves passing a fixed point per second
(8) What is the amplitude?
equal to half the wave height
(8) What is wave height?
vertical distance from crest to trough
What creates a wave?
WINDS creates waves in oceans
What are other disturbances that cause waves?
earthquakes and the gravitational pull of sun and moon
What are tsunamis?
seismic sea waves created by Earthquakes
What are Earthquakes?
vertical movement along faults
What are tides?
long waves created by gravitational pull of the sun and moon
What are deep water waves?
waves tahat occur in water that is deeper than the wave base, these waves do not “feel” the bottom
What is the depth of deep water wave?
deeper than halve the wavelength of the wave
Depth of a shallow water wave
less than L/20
What are Shallow water Waves?
waves that occur in depths less than 1/20 of wavelength and feel botto
What are diurnal tides?
occur once daily, have one high and one low tide per day of about equal amp.
What is a semidiurnal tide?
occur twice daily (2 high and 2 low) about = ample.
What is a mixed tide?
occur twice daily (2 high and 2 low) but exhibit significantly unequal amplitudes
What was a result of the wave lab?
waves got closer together an taller as it reached the beach also slowed down
What is an amphidrome?
(9) What are the limiting factors of primary productivity?
(9) What are the primary producers of coral reefs?
(9) What are the processes through with primary production occurs?
(9) What is biological magnification?
(9) What amount of energy is transferred from level to level in a food chain?
(9) What is the red field ratio and how do you use it to determine limiting nutrients ?
(9) How do you make a food chain and a food web?
(9) What is the difference among primary producers, primary consumers, secondary consumers, and decomposers?
(9) problems similar to 11 and 12 from lab 9
