Atmospheric Physics and Humidity Questions

Multiple choice geography humidity and clouds atmosphere and its structures elements of weather and climate : temperature what is around us? the atmosphere elements of weather and climate :humidity

In air, amount of water vapor is classified as ______.

    1. wind

    2. precipitation

    3. humidity

    4. temperature
    Reveal answer Fill a bubble to check yourself
    C Correct answer
    Explanation

    The amount of water vapor in the air is known as humidity. It can make hot temperatures even more unbearable than they already are. It affects both weather as well as climate. It also affects global climate change. Both low humidity as well as high humidity is harmful for us. Humidity is of two types:- Absolute humidity and Relative humidity.

    Multiple choice geography humidity and clouds atmosphere and its structures elements of weather and climate : temperature what is around us? the atmosphere elements of weather and climate :humidity

    1. Temperature

    2. Humidity

    3. Visibility

    4. Sunlight

    D Correct answer
    Explanation
    • Weather is the state of the atmosphere at a particular place and time. Temperature, humidity, and visibility are the atmospheric phenomena hence part of the weather.
    • Sunlight is independent of the atmosphere, thus option D is correct.

    Multiple choice zoology global environmental change causes of greenhouse effect global warming adaptation in animals

    If there is no $CO _2$ in the atmosphere, what would happen to the earth's temperature?

    1. It would, be less than the present.

    2. It would,be the same as present.

    3. It would be higher than the present.
    4. It depends on the $0 _2$ content of air.
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation

    When carbon dioxide and other air pollutants are collected in the atmosphere they absorb sunlight that has bounced from the earth’s surface. This leads to an increase in the earth's average surface temperature and is called global warming. When there is no carbon dioxide in the atmosphere, the temperature of the Earth's surface will be less than the present temperature. 

    Thus, the correct answer is option A. 

    Multiple choice physics energy production causes of greenhouse effect global warming adaptation in animals

    The increase of carbon dioxide gas in atmosphere will cause

    1. decrease in temperature

    2. increase in temperature

    3. no change in temperature

    4. nothing can be said
    Reveal answer Fill a bubble to check yourself
    B Correct answer
    Explanation

    Carbon dioxide is main cause of green house effect. The greenhouse effect is the rise in temperature that the Earth experiences because certain gases in the atmosphere (water vapor, carbondioxide, nitrous oxide, ozone, methane, for example) trap energy that comes from the sun.
    Thus, increase of carbon dioxide gas in atmosphere will cause increase in temperature.

    Multiple choice commercial applications management of natural resources unequal distribution of resources protecting our environment rules are for everyone

    Conning occurs in neutral atmosphere, when wind velocity is greater than

    1. 32 km per hour

    2. 42 km per hour

    3. 52 km per hour

    4. 72 km per hour
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation

    Coning is a type of plume behavior in air pollution meteorology. It typically occurs under neutral stability conditions when wind speeds are moderate to high, often cited as greater than 32 km/h.

    Multiple choice chemistry rocks and minerals coal and its products study of coal coal

    Ratio of primary air to secondary air increases with increase in the rank of coal, because the:

    1. ratio of fixed carbon to volatile matter increases

    2. high rank coals have higher amount of volatile matter

    3. calorific value of the coal increases

    4. oxygen content progressively decreases
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation

    Ratio of primary air to secondary air increases with increase in the rank of coal because the ratio of fixed carbon to volatile matter increases.

    Multiple choice geography major domains of the earth atmosphere and its structures what is around us? the atmosphere the earth's structure components of earth earth and structure

    Which of the following statements is wrong?

    1. Absolute humidity is expressed in grams per cubic metre of air
    2. 1$^o$C of temperature is reduced with every 165 metres of height

    3. When the temperature of air increases, its capacity to hold moisture decreases

    4. The higher the temperature the lower is the air pressure
    Reveal answer Fill a bubble to check yourself
    C Correct answer
    Explanation

    When air temperature increases, the capacity of air to hold moisture (water vapor) actually increases, not decreases. This is a fundamental principle of meteorology.

    Because of the compressibility of air, more than $50$% of the mass of the atmosphere is in its _________________.

    1. Lower $3.6$ miles
    2. Below $18$ mile level
    3. Beyond $18$ mile level up to $40$ miles
    4. Beyond $40$ miles
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation

    Due to gravity, air is most dense near the surface. More than 50% of the Earth's atmospheric mass is concentrated within the first 5-6 kilometers (roughly 3.6 miles) of altitude.

    Multiple choice evs let's play with water law of constant proportion - i law of constant proportion law of definite proportions

    When you get in your car in the morning and are breathing warmer air, the warm air comes into contact with the cooler windshield and forms a foggy window. It is an example of :

    2. sublimation

    3. condensation

    4. both A and C
    Reveal answer Fill a bubble to check yourself
    C Correct answer
    Explanation

    Condensation is the process by which water vapor in the air is changed into liquid water.Cloud formation is caused by condensation of water vapor in the atmosphere condensing into a liquid state. Thus Option C is correct.

    The mirror in the bathroom during a shower becomes foggy due to:

    1. condensation

    2. evaporation

    3. sublimation

    4. both A and B
    Reveal answer Fill a bubble to check yourself

    An atmosphere:

    1. Is a unit of pressure

    2. Is a unit of force

    3. Gives an idea of the composition of air

    4. Is the height above which there is no atmosphere
    Reveal answer Fill a bubble to check yourself
    A Correct answer
    Explanation

    An atmosphere is defined as the unit of pressure because we use to write the atmospheric pressure in terms of the $atm$.


    So, it is a unit of pressure. Option $A$ is correct.
