Questions Related to the properties of sea water

State whether these sentences are true (T) or false (F).
The level of seawater remains the same everywhere.

geography the properties of sea water properties of sea water oceanic salinity and oceanic temperature oceans : temperature, salinity and density circulation of ocean water

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

False,

 Seawater level varies depending on the varying gravitational signature. For example, a seamount (a large mountain within the sea) pulls a large volume of water towards itself, resulting in an elevated surface near the mount. Due to the varying geographical structure of the planet, the sealevel varies with latitude and longitude.

The heavier silicates named 'Sima' or silica + magnesium are most aboundant in the __________.

geography the properties of sea water properties of sea water oceanic salinity and oceanic temperature oceans : temperature, salinity and density circulation of ocean water

  1. Crust

  2. Core

  3. Mantle

  4. Ocean floors

Show answer
Correct Option: D
Explanation:

The heavier silicates named 'Sima' or silica + magnesium are most aboundant in the ocean floor.

These are a mix of minerals like gold, silver, copper, lead, zinc, and rare earth metals like molybdenum, tellurium, and titanium that form along the ocean floor—near underwater volcanic vents. Finally, there are cobalt-rich ferromanganese (Fe-Mn) crusts that form a layer of the ocean floor.

The ocean bottom relief are made due to the __________ interactions.

  1. Volcanic

  2. Erosional

  3. Depositional

  4. All of these

Show answer
Correct Option: D

The movements in the ocean water is/are ___________.

geography the properties of sea water properties of sea water oceanic salinity and oceanic temperature oceans : temperature, salinity and density circulation of ocean water

  1. Tides

  2. Waves

  3. Ocean currents

  4. All of these

Show answer
Correct Option: D
Explanation:

Ocean water is constantly in motion: north-south, east-west, alongshore, and vertically. Seawater motions are the result of waves, tides, and currents. Ocean movements are the consequence of many separate factors: wind, tides, Coriolis effect, water density differences, and the shape of the ocean basins.

The oceans are important because _________________.

geography the properties of sea water properties of sea water oceanic salinity and oceanic temperature oceans : temperature, salinity and density circulation of ocean water

  1. They are storehouse of water vapours

  2. Water is available for agriculture

  3. They moderate the climate of coastal regions

  4. None of these

Show answer
Correct Option: C
Explanation:

The oceans absorb heat near the equator and then transport that solar energy to polar regions. The oceans also moderate the climate within a region. Along with coastal areas, summer temperatures are not as hot, and winter temperatures are not as cold, because water takes a long time to heat up or cool down.

The Panama Canal shortens the distance between _________________.

geography ocean properties of sea water the properties of sea water oceanic salinity and oceanic temperature

  1. The Atlantic Ocean and the Mediterranean sea

  2. The Red sea and the Arabian sea

  3. The Pacific and the Atlantic oceans

  4. The Atlantic ocean and the Indian ocean

Show answer
Correct Option: C
Explanation:

The Panama Canal is a waterway that connects the Atlantic and the Pacific Ocean. Before the canal was opened in 1914 ships had to travel around the southern tip of South America to get from the Atlantic to the Pacific Ocean. The Panama Canal shortens the journey by about 11000 km.

The capital of Tasmania is _______.

  1. New castle

  2. Hobart

  3. Launceston

  4. Perth

Show answer
Correct Option: B

The name of the canal which links Pacific and Atlantic Ocean, is _________.

geography ocean properties of sea water the properties of sea water oceanic salinity and oceanic temperature

  1. Panama

  2. Suez

  3. Kiel

  4. None of these

Show answer
Correct Option: A

OTEC refers to ________.

geography ocean properties of sea water the properties of sea water oceanic salinity and oceanic temperature

  1. Oceanic mineral resources

  2. Tidal and wave energy.

  3. Ocean thermal energy conversion.

  4. None of these

Show answer
Correct Option: C
Explanation:

Ocean thermal energy conversion (OTEC) uses the ocean thermal gradient between cooler deep and warmer shallow or surface seawaters to run a heat engine and produce useful work, usually in the form of electricity
