Narrow valleys are favorable to inversion because horizontal air movement is

  1. Decreased

  2. Favorable

  3. Possible

  4. Restricted


Correct Option: D

The ratio of the mass of water vapor in a given volume (parcel) of air to the mass of the remaining dry air describes the:

  1. Absolute humidity

  2. Mixing ratio

  3. Relative humidity

  4. Dew point


Correct Option: B

The temperature at which water boils depends mainly on:

  1. Air temperature

  2. Relative humidity

  3. Air pressure

  4. Air density


Correct Option: C

Major source of air pollution is

  1. Fossil fuels

  2. Burning of wood

  3. Biogas

  4. Cow dung cakes.


Correct Option: A
Explanation:

Burning of fossil fuels cause major harms. The burning of fossil fuels like coal, natural gas, petroleum in automobiles, industries and thermal plants leads to increase in air pollution.

What was Aldo Leopold 'philosophy' about humans ethics?

  1. Environmental Ethics

  2. Sustainable Ethics

  3. Land Ethics

  4. Frontier Ethics


Correct Option: C

Land breeze blows during _________

  1. Summer

  2. Winter

  3. Day

  4. Night


Correct Option: D
Explanation:

At night, the water cools down more slowly than the land. So, the cool air from the land moves towards the sea. This is called the land breeze.

The wind flows fromĀ 

  1. High pressure to low pressure

  2. Low pressure to high pressure

  3. Low temperature to high-temperature

  4. All of the above


Correct Option: A
Explanation:

The uneven heating of the air causes the flow of the wind. It takes place due to the greater intensity of sunlight at the equator as compared to that of poles. Due to greater intensity of sunlight at the equator the air gets heated up, the air molecules absorb the heat and the intermolecular forces between the air molecules become weak and its kinetic energy increases. The air molecules becomes lighter and rises up. This creates a low pressure zone on the equator while high pressure zone exist at the poles. So, the air moves from high pressure to the low pressure.

So, the correct answer is option A.

Hot air over the land rises up and creates.

  1. Low pressure over the land

  2. High pressure over the land

  3. High pressure over the water bodies.

  4. All of the above


Correct Option: A

The uneven heating near the equator takes place because of

  1. The intensity of sunlight

  2. The direction of sunlight

  3. The density of flora and fauna

  4. None of the above


Correct Option: A
Explanation:

The uneven heating of the air takes place due to the greater intensity of sunlight at the equator as compared to that of poles. Due to greater intensity of sunlight at the equator the air gets heated up, the air molecules absorbs the heat and the inter molecular forces between the air molecules becomes weak and its kinetic energy increases. The air molecules becomes lighter and rises up. This creates a low pressure zone on the equator while high pressure zone exist at the poles.

So, the correct answer is option A.
