Which of the following is a type of wave ____________.

geography ocean and man movements of ocean and sea water oceanic circulations circulation of ocean water oceans : temperature, salinity and density tsunami and floods

  1. Ripples

  2. Seas

  3. Swells

  4. All are the types of waves

Show answer
Correct Option: D
Explanation:

Ripples are the instant effect of wind on water and they die down as quickly as they form, as the surface tension of the water dampens their efforts.

Waves always travel in the same direction as the wind is blowing: if the wind changes then the waves change with it. Wave size is determined by the strength of the wind, the length of time it has been blowing and the distance it has blown over or the ‘fetch’.

When strong winds blow for longer than a few hours, it gives the water sufficient energy that it then takes on a character of its own. This character and movement is known as swell, and it will march across open areas of water independent of the wind.

The water of which of the following seas is most saline?

movements of ocean and sea water oceans : temperature, salinity and density geography tides and ocean currents circulation of ocean water oceanic circulations study of water pollution threats to water resource pollution and environment

  1. Black Sea

  2. Dead Sea

  3. Baltic Sea

  4. Red Sea

Show answer
Correct Option: B
Explanation:

With 33.7% salinity, the Dead Sea is one of the world's saltiest bodies of water. The Dead Sea is landlocked and in the lowest valley on earth. All the minerals of the surrounding countryside get washed into one pool, which in turn gets baked by the sun. This concentrates the salts so much that the Dead Sea is 10 times as salty as the ocean.
