The question asks for the technical term for water vapour present in the air. We need to identify the correct meteorological term from the given options.
B) Humidity is the general term used to describe the amount of water vapour present in the air. It can be expressed in various ways, such as absolute humidity, specific humidity, or relative humidity.
The question asks about the forms in which water exists in the atmosphere. To answer this, recall the different states of matter and how water cycles through them in the Earth's atmosphere.
A) Gaseous, liquid and solid — This option correctly identifies all three forms (states of matter) in which water is found in the atmosphere.
The question asks for the term that describes the actual amount of water vapour present in the atmosphere, expressed as the weight of water vapour per unit volume of air. We need to identify the correct meteorological term among the given options.
Based on the definitions, absolute humidity is the term that precisely matches the description provided in the question.
Correct Option: B) Absolute humidity
The question asks to identify the term that describes the percentage of moisture present in the atmosphere compared to its maximum capacity at a given temperature. This is a direct definition question related to atmospheric humidity.
C) Relative humidity is the ratio of the amount of water vapor actually present in the air to the maximum amount of water vapor the air can hold at a given temperature, expressed as a percentage. It indicates how close the air is to saturation.
The question asks where relative humidity is generally greater. Relative humidity is a measure of the amount of water vapor in the air compared to the maximum amount of water vapor the air can hold at a given temperature. It is directly related to the availability of water for evaporation.
Correct Option: C) Oceans provide a vast surface area for continuous evaporation, leading to a constant supply of water vapor into the atmosphere above them. This results in generally high relative humidity over oceanic regions.
The question asks for the term describing air that holds the maximum possible amount of moisture at a given temperature. This relates to the concept of humidity and saturation in meteorology.
Correct Option: A) Saturated. When air contains moisture to its full capacity at a given temperature, it is said to be saturated. This means it cannot hold any more water vapor, and any additional moisture or a decrease in temperature will lead to condensation.
