2. When a profile of a feature is drawn to scale, the horizontal and vertical scales must be the same. Does your profile give an accurate picture of the ocean floor? Explain. (20pts)

Answer:

As explained below.

Explanation:

  • The structure if the ocean floor from 160 km to 1050 km east of new jersey is abyssal plains and hill, between the depth of 2000 km to 4500 km i.e 5100 meters deep lies the starting point of ocean deeps and deep-sea ridges, between the 5300 km to 5500 km i.e depth of 920 meters down lies the Continental slope  
  • These are represented by the bathymetric profiles which provide a skyline view of hills and slopes, valleys and depression and .there horizontal and vertical ratios must be the same as 1:1.
  • However, they are generally so small that it's impossible to see them the profile sheet is drawn by manually selecting the VE = Horizontal Scale/Vertical Scale.  
  • As vertical exaggeration takes place the increasing features on a profile, hills appear to be higher, valleys deepen and the slopes among them get much steeper. Slopes, that, in reality,  are more gentle; steep slopes will appear to be stretched.
