Scientific Notation:  Pangea & Continental Drift
Supercontinent Pangea Breaks Apart illustration
In the relatively distant past, geologists believe that the seven current day continents formed one super continent known as Pangea.  The theory of continental drift suggests that after tectonic forces splintered Pangea, several pieces of it eventually "drifted" into the positions which comprise the various continents as we know them today...
  1. List the names of the seven present-day continents:
    1.  
    2.  
    3.  
    4.  
    5.  
    6.  
    7.  

  2. Currently, Africa and South America are about 5000 km apart.  The rates at which the continents have been drifting apart has been measured to be in the range of 1 cm/yr to 10 cm/yr.  Determine the corresponding range of ages (in years) at which the continent of Pangea would have begun to break apart if the rate of drift has remained constant.
