Ocean – Revision Test

    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.        F – Only in isolated spots with hot springs

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

   3. Salt water freezes at lower temperature. T

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

                           F - About the same (Fig.8)

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

   6. Fishing industry is often located in swelling areas.      F – upwelling (výstup hlubin.
   proudu)

   7. Blue color is absorbed most rapidly in water.   F – least

   8. Deep ocean temperatures are highly variable

   F only slightly from 5°C to less than –1°C

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

   10. The tides are usually weaker at the head (the narrow end) than at the mouth of a V-shaped
   bay.                         F  -  the other way round, p. 410 wider end

   Bulk -  majority, almost entire, the biggest part                           entire  - whole

   Coincide – match, agree, correspond, synchronize                     restricted – limited

   successive (wave) – following, consecutive, sequential  scarcely – hardly, barely

   temperate – moderate, mild (x severe)                 rarely – seldom, infrequently

   vertical mixing – downward                                    excess – redundant, surplus

   Explain these terms:

   Brine pool – body of sea (or underground) water with very high salinity (high contents of
   minerals)

   Clockwise – in the same way as the rotating hands of a clock

   Pounding – repeated heavy blows

   Waterline – 1.  Line of sea water given by high or low water mark ( boundary between
                                 the earth´s surface and water)

   2. how deep the ship is under the water (čára ponoru lodi)

   Line painted on a hull (trupu) of a ship to correspond with the surface of the water when the
   ship is afloat on an even keel (= vyvážená)
