Acid precipitation is now regarded as a serious problem in some European and Asian countries. Its major cause or source is __________________.

  1. discharge of effluents into neutral or slightly alkaline land where the acidic components precipitate

  2. emissions of sulphur oxides and nitrogen oxides from thermal power plants and burning the fossil fuels; these oxides dissolve in atmospheric water vapour and fall back on earth as acid rain

  3. natural carbondioxide released during respiraion of living organisms dissolves in water, forming carbonic acid which is chief contributor to acidity in rain water

  4. chloroflurocarbons readily react with various chemicals near the earth's surface, producing acidic intermediates which cause acid precipitation


Correct Option: B
Explanation:

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants, known as acid rain.

Precipitation is any type of water that forms in the Earth's atmosphere and then drops onto the surface of the Earth.

The rain that falls from clouds but freezes before it reaches the ground is called sleet or ice pellets.

Snow is precipitation that falls in the form of ice crystals

Hail  forms when very cold water droplets freeze, or turn solid, as soon as they touch things like dust or dirt

Water vapor in the atmosphere is visible as clouds and fog.

When water particles condenses on air and dust, it forms __________.

  1. mist

  2. fog

  3. frost

  4. vapour


Correct Option: A
Explanation:

It forms mist. It is a phenomenon caused by the small water droplets of water suspended in the air. When the warm moist air meets the sudden cooling, mist is formed.

Isopleth for depth is  _____________,

  1. Isobaths

  2. Isohaline

  3. Isohyet

  4. None of these


Correct Option: A
Explanation:

Isopleth for depth is Isobaths.
A line similar to an isobath indicating depth below the earth's surface of an aquifer or other geological horizon is isobath.

Shift of population from villages to cities is __________.

  1. Urbanization

  2. Ruralization

  3. Communalization

  4. None of these


Correct Option: A
Explanation:

Urbanization is a process where population shifts from rural to urban areas. Urban areas become large as people begin to live and work in increasing numbers. Ruralization is an act of becoming rural. A region getting the appearance, features of rural area and the movement of people to country side. Communalization refers to abolition of private ownership of property, resources and share the collective resources among the local community for the common good.

Holes in the ___________ layer of the atmosphere allow ____________ ___________ of the sun which causes ____________.

  1. Ozone layer, gamma rays, brain tumour

  2. Ozone layer, harmful rays, skin cancer

  3. Greenhouse, x rays, brain tumour

  4. Ozone layer, alpha rays, brain tumour


Correct Option: B
Explanation:

Air pollution leads to the greenhouse effects due to the constant emission of poisonous gases from vehicles, households and industries which the atmosphere cannot use. Gases remain trapped inside the atmosphere causing the global temperature to rise. This is called global warming. This has resulted in holes in the ozone layer due to which harmful rays of the sun are allowed to enter the earth's atmosphere causing skin cancer and various other ailments. 

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

    1. wind

    2. precipitation

    3. humidity

    4. temperature


    Correct Option: C
    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.
