Sdsu Oceanography 100 Final Questions
With Complete Solutions
What is the origin of the Earth? Formed out of a solar nebula
What are the origins of Life? Archaea - the oldest origin of life on Earth
What is kinetic energy? The energy of motion
What is heat energy? Energy created by particles of matter rubbing together
What is density? A measurement of the amount of matter in a given volume of something.
(mass per unit volume)
What is convection? Transfer of heat through currents caused by difference in
temperature, which cause difference in density (liquids and gases).
What is bioaccumulation? as you go up the base of the food chain, the level of mercury is
more concentrated than the base of the food chain
, Sdsu Oceanography 100 Final Questions
With Complete Solutions
How does biodegradation work? Nature can decompose the pollutant because it is made
by the earth itself
How does photo-degradation work? Plastic degraded by sun, meaning it gets smaller
What is diffusion? going from a high concentration to a low concentration
What are the 3 plate boundaries? Divergent, Convergent, Transform
Where are trenches located? At subduction zones
What are hot spots? Volcanic centers resulting from hot materials produced deep in the
mantel
What is our plate boundary here in San Diego? Transform Boundary
Where is our plate boundary located? San Andreas Fault
, Sdsu Oceanography 100 Final Questions
With Complete Solutions
In which direction are we moving, considering moving plates? Northwest
What are the 2 continental margins of Marine Provinces and where are they found? 1.
Passive Margin: within a plate, little tectonic activity, larger shelf, Atlantic-type
2. Active Margin: at a plate boundary, narrow shelf, active tectonics, Pacific-type
What are the characteristics of the water molecule? 2 Hydrogen, 1 Oxygen
Why is water polar? Hydrogen is positive and oxygen is negative (opposites attract)
