26. What is the weight of actual amount of water vapour present in unit volume of air called?
[A] Absolute Humidity
[B] Relative Humidity
[C] Condensation
[D] Specific Humidity
Show Answer
Correct Answer: A [Absolute Humidity ]
Notes:
Humidity is the amount of water vapour present in air.
Absolute Humidity is the weight of actual amount of water vapour present in unit volume of air.
Relative Humidity is the Ratio of water vapour in air at a particular temp. to total amount of water vapour required to saturate the same air at same temperature. It is expressed in %
Specific Humidity is the Weight of water vapour present in per unit weight of air. It is not affected by change in pressure or temperature.
27. What is the process in which water vapour directly condenses into solid form called?
[A] Evaporation
[B] Condensation
[C] Sublimation
[D] Precipitation
Show Answer
Correct Answer: C [Sublimation]
Notes:
Sublimation is the process in which water vapour directly condenses into solid form.
Condensation is the process of transformation of water vapour into water.
Evaporation is process by which water or a liquid is transformed from liquid to gaseous state.
Precipitation is the condensation of water vapor in air in form of water droplets or ice.
28. Which among the following statements is/are correct about Cyclones?
- It is any high-pressure area with winds spiralling inwards.
- It rotates anti-clockwise in Northern Hemisphere and clockwise in Southern Hemisphere.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: B [Only 2]
Notes:
Cyclone is any low-pressure area with winds spiralling inwards. Cyclones rotate anti-clockwise in Northern Hemisphere and clockwise in Southern Hemisphere. The process of Cyclone formation and intensification is called Cyclogenesis.
29. Which among the following statements is/are correct about the Euphoric Zone of the ocean water?
- There is a steep fall in temperature in this zone.
- It contains about 18 percent of the total volume of water in the ocean
- It lies between 100 metres and 1000 metres.
Select the correct code from the options given below:
[A] Only 1 & 2
[B] Only 3
[C] Only 2 & 3
[D] None of the above
Show Answer
Correct Answer: D [None of the above]
Notes:
The Surface Zone is also called as the Photic zone or the Euphoric Zone. It is the upper layer of the ocean. In this layer, the temperature and salinity are relatively constant. It contains about 2 percent of the total volume of water in the ocean.
It contains about 2 percent of the total volume of water in the ocean. It is limited to a depth of about 100 meters.
30. Which among the following statements is/are correct about Ocean Temperature?
- The rate of decrease of temperature with increasing depth from equator towards the poles is not uniform.
- The polar seas have only one layer of cold water mass from the ocean surface to the deep ocean floor.
Select the correct code from the options given below:
[A] Only 1
[B] Only 2
[C] Both 1 & 2
[D] Neither 1 & 2
Show Answer
Correct Answer: C [Both 1 & 2]
Notes:
Though the surface temperature of the seas decreases from equator towards the poles but the temperature at the ocean bottoms is uniform from the equator towards the pole, which means that the rate of decrease of temperature with increasing depth is more rapid near the equator than towards the poles.
The polar seas have only one layer of cold water mass from the ocean surface to the deep ocean floor.
