MAR 105 Laboratory Dr. J. Anastasia 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
