Oceans provided abundant ______ resources like fish and salt.

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. agricultural

  2. food

  3. flora and fauna

  4. minerals

Show answer
Correct Option: B
Explanation:

Oceans provided abundant food resources like fish and salt.

The ocean is an important source of food and other resources. Since well before recorded history, humans have used the sea as a source of food. While only 5% of the protein consumed by world populations comes from the sea, it is still an important contribution to the diet of millions of the world's inhabitants.

Which of the following effects the temperature of sea water?

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. Cyclones

  2. Rainfall

  3. Salinity

  4. All of above

Show answer
Correct Option: D
Explanation:

Temperate is one of the major property of seawater. It always varies from region to region. The surface temperature of the sea water decreases from the equatorial area towards the poles. Some factors which effects the temperature of sea water are:-

  • Cyclone
  • Rainfall
  • Salinity
  • ocean currents
  • pollution

Which of the following is land-locked sea?

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. Timor sea

  2. Aral sea

  3. Red sea

  4. North sea

Show answer
Correct Option: B
Explanation:

As the salinity of the landlocked seas is more, the temperature of these landlocked seas is higher than the open seas. Aral sea is landlocked sea.

Ocean floor is mined for _____.

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. gold

  2. silver

  3. oil

  4. diamond

Show answer
Correct Option: C
Explanation:

Crude oil and natural gas occur in 'pockets' under the ground. Sometimes the deposits are found under the sea bed. Like other deposits, they are extracted by drilling a hole down through the rocks into the oil or gas. For undersea deposits, the drills are mounted on a platform called a drilling rig.

What are the causes of ocean currents?

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. Density difference in water

  2. Effect of winds

  3. Temperature and salinity variation

  4. Gravity

  5. All of these

Show answer
Correct Option: E
Explanation:

The movement of ocean waters or ocean currents takes place due to the effect of earth's rotation, wind difference, salinity and density of seawater, etc. The current in the ocean is originated due to the combined effect of all these factors acting internally as well as externally. 

Most of the gems and pearls are from _____.

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. land

  2. ocean

  3. desert

  4. gas

Show answer
Correct Option: B

After how much depth the temperature of sea water is uniform?

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. 1000m

  2. 1500m

  3. 2000m

  4. 2500m

Show answer
Correct Option: C
Explanation:

After 2000m, the temperature of the seawater is uniform everywhere. It is around $4 ^oC$ according to depth. And therefore, the water of greater depths does not freeze.

Which of the following is the major property of seawater?

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. Rainfall

  2. Snowfall

  3. Temperature

  4. All of above

Show answer
Correct Option: C
Explanation:

Temperate is one of the major property of seawater. It always varies from region to region. The surface temperature of the sea water decreases from the equatorial area towards the poles.

Which of the following area is known as hot deserts of the world?

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. Mid-latitudinal zones

  2. Temperature regions

  3. Tropical zone

  4. Polar area

Show answer
Correct Option: A
Explanation:

In mid-latitudinal zones, rainfall is less and the supply of freshwater from various rivers is also low. This zone has the hot deserts of the world. 

In seas where the supply of freshwater exceeds the rate of evaporation, salinity is _______.

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. High

  2. Low

  3. Not effected

  4. None of these

Show answer
Correct Option: B
Explanation:

In seas where the supply of freshwater exceeds the rate of evaporation, salinity is low. Near the estuaries generally the salinity is low because ample amount of fresh water enters the sea or ocean.
