Major source of air pollution is

commercial applications issues of the environment excessive consumption of resources atmosphere and its components atmosphere- wind

  1. Fossil fuels

  2. Burning of wood

  3. Biogas

  4. Cow dung cakes.

Show answer
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.

Correct Option: C

Land breeze blows during _________

commercial applications issues of the environment excessive consumption of resources atmosphere and its components atmosphere- wind

  1. Summer

  2. Winter

  3. Day

  4. Night

Show answer
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 from 

commercial applications issues of the environment excessive consumption of resources atmosphere and its components atmosphere- wind

  1. High pressure to low pressure

  2. Low pressure to high pressure

  3. Low temperature to high-temperature

  4. All of the above

Show answer
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
