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

Which of the following effects the temperature of sea water?

  1. Cyclones

  2. Rainfall

  3. Salinity

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
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

Ocean floor is mined for _____.

  1. gold

  2. silver

  3. oil

  4. diamond

C Correct answer
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?

  1. Density difference in water

  2. Effect of winds

  3. Temperature and salinity variation

  4. Gravity

  5. All of these

E Correct answer
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.

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

  1. 1000m

  2. 1500m

  3. 2000m

  4. 2500m
Reveal answer Fill a bubble to check yourself
C Correct answer
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 area is known as hot deserts of the world?

  1. Mid-latitudinal zones

  2. Temperature regions

  3. Tropical zone

  4. Polar area
Reveal answer Fill a bubble to check yourself
A Correct answer
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 _______.

  1. High

  2. Low

  3. Not effected

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

Which factor among the following is true in respect of salinity?

  1. After evaporation amount of salt remains same

  2. After evaporation amount of salt increase

  3. After evaporation amount of salt decreases

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Because of the sun's heat, evaporation happens at a faster rate. Evaporated water turns into water vapour and reduces in quantity. But amount of salt remains the same in the remaining water and therefore the salinity of the water increases.
