Lab Quiz 1 Review Sheet
Lab 1: The Scientific Method
 know the steps in the scientific method (Observation, Questions, Hypothesis,
Experimentation, Conclusions, Predications) and be able to provide examples of
each
 know the definition of density
 know the formula used to calculate density
 know how to figure out density of a water sample or an object if given a scale and
glassware to measure volume

know that salt water is denser than fresh water and that the density of pure water
is 1 g/cm3

be able to explain (in general) why boats float and how to know if something
would float on water (density must be less than 1)
Labs 2, 3 &4: Plate Tectonics and Ocean Profile Labs
 know the pattern we see in paleomagnetic data on rocks on either sid eof a MidOcean Ridge or Rise
 know the pattern of the age of the ocean floor and what it indicates about seafloor
spreading (new ocean floor formed at the ridges and rises)
 know the ocean crust is formed through volcanic activity at Ridges and Rises
 know the ocean floor is destroyed at subduction zones where trenches occur
 know that the United States is located on the North American Plate and where the
boundaries of this plate are
 be able to identify active and passive continental margins if shown a map with
plate boundaries drawn on it.
 Be able to identify plates that have oceanic and/or continental crust
 know the three types of plate boundaries and how plates move relative to each
other at each and one example of a place in the world where each type is found
 be able to identify each type of plate boundary on an ocean contour graph based
on what features you see there (ex: trench means a convergent plate boundary,
mid-ocean ridge means a divergent plate boundary)
 know what makes one plate subduct under another and what features of the ocean
floor you would see at a subduction zone
 know the various features of the ocean floor (continental shelf, continental slope,
continental rise, trenches, deep sea floor, mid-oceanic ridge)
o be able to label them on a diagram or draw a typical profile
Lab 5: Salinity, Temperature and Density
 know what a refractometer is and how to use it to measure salinity
 know what a thermocline and halocline are and where in the ocean (which regions of
the globe, what time of year) each is likely to be found
 know how temperature affects water density – warmer water is less dense and floats
on top of colder water
 know how salinity affects water density – fresh water (very low salinity) is less dense
and floats on top of saltier water
 be able to label the three layers of the ocean if shown a graph of temperature versus
depth or salinity versus depth
 know how to read a TSD diagram and be able to use it to figure out density, salinity
or temperature, if given the other two measurements
Lab 6: Ocean Circulation
 know that warm air is less dense and it rises
 know that cold air is more dense and it sinks toward the earth's surface
 know that rising air creates an area of low pressure at the earth's surface
 know that sinking air creates an area of high pressure at the earth's surface
 know that the earth's shape and rotation lead to the Coriolis Effect
 know how moving objects (like wind or currents) curve clockwise in the Northern
Hemsiphere and counterclockwise in the Southern Hemisphere due to the Coriolis
Effect
 be able to name and draw the location and direction of the three main wind bands
in each hemisphere (Trade Winds, Westerlies and Polar Easterlies
 know that the winds and the Coriolis effect combine to create large circular
surface currents in the oceans called gyres
 Know that the Gulf Stream is the surface current that runs along the East Coast of
the U.S. from the tropics toward the north, carrying warm water
 Know that the Gulf Stream is one of the currents on the North Atlantic Gyre
 be able to draw, with arrows, the direction and location of the North American
Gyre on a map
