    True or False? Cross out the false statements and correct them.

   

   1. Concentrated amounts of dissolved solids can be found anywhere along all the mid-ocean
   ridges.       

   2. Warmer surface water near the equator is less dense than the cooler surface water near the
   poles.

   3. Salt water freezes at lower temperature.

   4. Deep ocean water at the equator is cooler than the surface water near the poles.

                          

   5. At base level the orbital motion of a wave almost disappears. 

   6. Fishing industry is often located in swelling areas.    

   7. Blue color is absorbed most rapidly in water. 

   8. Deep ocean temperatures are highly variable

   

   9. Local storms may also affect the timing and the strength of the tides along a coastal
   area.   

   10. The tides are usually weaker at the head (the narrow end) than at the mouth of a V-shaped
   bay.
