  1. 1. 2/24/12 A/B DayLEQ: How do we classify marine, or oceanorganisms that live in the hydrosphere?1. What is polarity?2. What is cohesion?3. What is adhesion?4. Give one example of cohesion.5. Give one example of adhesion.
  2. 2. Today’s LEQ: How do we classify marine, or ocean organisms that live in the hydrosphere?By the end of today, you should be able to…1. Compare and contrast saltwater and freshwater2. Identify the three different types of organisms that live in marine environments3. Classify organisms as benthos, plankton, or nekton

  31. 31. Let’s Review!
  32. 32. Which of the following lists the layersof the earth, in order from MOSTDENSE to LEAST DENSE?a. inner core, outer core, mantle, crustb. crust, mantle, inner core, outer corec. outer core, inner core, mantle, crustd. inner core, outer core, crust, mantle
  33. 33. The best evidence that two land masseswere once connected is the discovery thatboth land masses…a. have the exact same climateb. exist on the same line of latitudec. have similar types of rocks and fossilsd. are in the same stage of the rock cycle
  34. 34. Which of the following statements providesthe best explanation for why Greenland,which is in the arctic, has fossils of tropicalplants?a. Greenland was once located near theequator and had a tropical climateb. plants carried seeds from the tropics toGreenlandc. Earth was once entirely tropicald. the fossils were carried to Greenland byocean convection currents
  35. 35. A plant fossil is found on the eastern coast ofBrazil. An identical fossil from the same timeperiod is found in western Africa. What is usedto explain this?a. seeds from plants were carried by marine lifeb. very few plants existed in the time periodc. plant fossils are too similar to tell one speciesfrom the otherd. the land areas from which the fossils camehave moved apart over time
  36. 36. Which of the following best describes thetheory of continental drift?a. Pangaea makes oceans seem larger thanthey areb. Pangaea will exist at some time in thefuturec. Pangaea broke apart due to convectioncurrentsd. Pangaea never existed
  37. 37. What is happening in this diagram?a. Pangaeab. core movementc. convection currentsd. continental theory
  38. 38. This diagram represents which of thefollowing? a) Subduction boundary b) Convergent boundary c) Divergent boundary d) Transform boundary
  39. 39. Mountain ranges, like theHimalayas for example, areformed by which kind of plateboundary? a) Subduction boundary b) Convergent boundary c) Divergent boundary d) Transform boundary
  40. 40. Off the coast of South America, a plate ofdense oceanic crust collides with a plate ofless dense continental crust. What happensat the boundary of these plates? a) The oceanic crust is forced to sink below the continental crust b) The continental crust is forced to sink below the ocean crust c) The oceanic and continental crust both sink below the lithosphere d) The oceanic and continental crust are forced up to form mountains
