We generally measure the depth of the Sea in _____________.

  1. Feet

  2. Fathoms

  3. Metres

  4. Nautical miles


Correct Option: B
Explanation:
Fathoms
Water depths are measured by soundings usually acquired by hydrographic surveys. The depths may be in either feet or fathoms (the chart will indicate which). A fathom is a nautical unit of measurement and is equal to six feet. Sonar devices are used to measure the depth of the sea.

  4. None of the above


Correct Option: B
Explanation:

Salinity is the saltiness or dissolved salt content in a body of water. Salinity is an important factor in determining many aspects of the chemistry of natural waters and of biological processes within it, and is a thermodynamic state variable that, along with temperature and pressure, governs physical characteristics like the density and heat capacity of the water.
