This process is known as thermohaline circulation. In the Earth's polar regions ocean water gets very cold, forming sea ice. As a consequence the surrounding seawater gets saltier, because when sea ice forms, the salt is left behind. As the seawater gets saltier, its density increases, and it starts to sink.
<u>From the given options which may suitably apply to the description of grid-lines of the map are

</u>
Option A describes that the grid-lines of the map are measure in degrees, which are very true as the grid are lined with angular measurement which thus be done in unit of angles and is in degrees only.
Option B says it develops the reference system which specifies about the area being plotted are grid depending upon the size which sets up the referential system of enumeration.
