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

B Correct answer
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.

B Correct answer
Explanation

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.

  2. fog

  3. frost

  4. vapour

A Correct answer
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.
